An inspection today, keeps the water slide closures away!
Water slides are a great attraction to any indoor or outdoor pool, and can provide hours of fun and excitement for children of all ages. Just the appearance of a twisty, colourful slide can bring multiple patrons into a facility to test it out.
Though a slide may seem like a simple piece of equipment, there are many aspects that need to be maintained and checked regularly to keep everything running smoothly, and looking great. In addition to regular maintenance, and annual slide inspections by Technical Standards and Safety Authority (TSSA), a slide mechanic can be a great asset to keeping your slide running how it’s supposed to be. In fact, in most jurisdictions it is required by TSSA to ensure the slide is being properly maintained. Yearly inspections, along with regular repairs and maintenance are performed by a licenced slide mechanic to prolong the life of your slide and most importantly, keeping your patrons safe and sound.
Like our own health, we don’t just visit the doctor’s office when there is something critically wrong with us. We try to be proactive in order to prevent serious health issues by visiting our doctor for regular check-ups. Your facilities slide should be treated in the same way. Regular check-ups or inspections by a slide mechanic are critical in maintaining the overall health in a water slides life span. Here are a few items inspectors will look for during their visits:
The joints that hold your slide together receive the most wear and tear on the slide. The friction of swimmer, after swimmer, after swimmer continually sliding over the joints will wear down the caulking that fills them in, forming low areas or uneven surfaces. These low spots will create a “bump” feeling when sliding over and if left untreated will eventually become uncomfortable for riders. Caulking should be inspected regularly and when required your slide mechanic will bring the caulking back up to the proper level, eliminating any comfort issues riders may have been experiencing.
Stemming from low areas in the slide joints, leaks can also pose a regular issue for water slides. Once a joints caulking gets worn down (or worn away completely), water will start to seep through the joints and slowly drip onto not only the deck below, but also the slides support structure. Water ponding on the deck, especially in the case of a tiled deck in an indoor facility, can cause a slip hazard for excited children who are in a hurry to get to the slide. Water dripping onto a slides support structure will not only create unsightly rusting of steel members, but over time can severely damage a slides structural integrity, resulting in very costly repairs. Annual visits by your slide mechanic will ensure that any leaks that may have developed are dealt with and eliminated before any serious damage can happen.
Hidden in the bowels of the pools mechanical room, and unseen to the public, as well as most of the staff is perhaps the most important part of a slide system. Operating daily, unheralded and often overlooked- though not as exciting in appearance as the slide itself, a slides pump and piping network provides the slide its life blood- water! A slide mechanic will ensure the heartbeat of the slide is working properly by checking for leaks, cracks, thumps and thuds that are not an element of a healthy system. Pressure and suction gauges are also checked to ensure that there are no issues internally.

The beauty about working in the aquatic industry is learning about all of the information and various components involved in the operation of a pool. It is a natural assumption that there is a hole in the ground and this perfect, pristine body of water is waiting to cool swimmers on a hot day. In actual fact, pool operation can be likened to learning a new language when it comes to the complexity of properly servicing and maintaining this water for people to enjoy.
For instance, there are hundreds of variables that differ for each application and need to be closely supervised to ensure there is no interruption in the pool’s operation, while at the same time safeguarding patrons. The most important component, which can be easily overlooked and can have the biggest impact on the longevity of the pool’s lifecycle, is the basic preventive maintenance practices that need to be policed and properly scheduled.
A small leak, for example, that is not attended to could result in a major leak only hours or days after it starts. If it is not repaired properly, it can result in pool closures and a hefty bill for the owner. It is important every aquatic facility has a schedule of daily, weekly, and monthly preventive maintenance practices in place to ensure the most optimal pool operation for years to come.
WHAT IS PREVENTATIVE MAINTENANCE?
Preventive maintenance refers to routine upkeep to ensure pool equipment continues to operate efficiently, whereby preventing any unanticipated downtime and the associated costs from equipment failure. It requires vigilant planning and scheduling of maintenance for equipment before there is an actual problem, as well as keeping accurate records of past inspections and servicing reports. Maintenance includes parts replacement, cleaning, tests, and chemical adjustments.
WHAT SHOULD A PREVENTATIVE MAINTENANCE PROGRAM LOOK LIKE?
Preventive maintenance involves the regular inspection of equipment where potential problems are detected and corrected before it fails. In practice, a preventive maintenance schedule may include things such as cleaning, water testing and chemical adjustments, repairs, inspections, replacing parts, and overhauls that are regularly scheduled, such as filter sand changes. This is why it is imperative that daily, weekly, and monthly checks are completed and recorded.
These inspections should involve much more than simply performing routine maintenance on the pool’s mechanical equipment and water chemistry. It should also entail keeping accurate records of every inspection, water test, and repair, as well as knowing the life expectancy of each part to understand the replacement and maintenance requirements. These records can help technicians anticipate a suitable time to change parts and can also help them to diagnose problems when they occur. If this due diligence is not followed, service interruptions will happen, resulting in downtime to resolve the problem at hand.
WHAT ARE THE BENEFITS?
Aside from protecting the owner’s investment, and ensuring their pool is operating to the best of its ability, preventive maintenance offers a number of other benefits, including:
Prolonged life of pool and spa equipment;
Minimal unplanned downtime caused by equipment failure;
Less unnecessary maintenance and inspections;
Fewer errors in day-to-day operations;
Improved reliability of equipment;
Fewer expensive repairs caused by unexpected equipment failure that must be fixed quickly; and
Reduced risk of injury.
In addition to being diligent with maintenance, there are also health and building codes that provide a guide for proper daily operation. These are enforced by inspectors to ensure the pool and spa environment is safe for bathers and the laws are being followed.
There are several simple maintenance procedures that can be easily overlooked, but without the proper attention, it can lead to major complications down the road if they are not completed.
PRIORITY MAINTENANCE PLAN
The heart of the pool is the filtration pump—without it the water would not be circulated through the filter, heater, or sanitization system, creating a potential health hazard for bathers. It is critical that regular checks and maintenance are completed on the pumps to avoid cloudy water, or even prevent an unexpected closure due to mechanical failure.
Simple things like cleaning the strainer basket (daily for an outdoor application and weekly for an indoor application) can have a drastic impact on the overall efficiency of the mechanical system. If the strainer basket is not cleaned regularly, a ‘load’ is put on the pump, forcing it to work harder to circulate the water that needs to be filtered, heated, and chemically treated before it is sent back to the pool. The harder the pump has to work, the more wear-and-tear is put on it. As a result, this can lead to mechanical seal failure, water clarity issues, as well as impact the overall performance of the entire system.
If maintenance is not completed regularly, the pump will fail and force a closure until it can be repaired or replaced. The water can become cloudy, increasing the amount of additional labour and chemicals required to get the pool back up and running. By completing simple pool maintenance, owners can improve the overall longevity of their investment.
DO NOT SKIMP ON SKIMMING
In a pool, the first 152 mm (6 in.) of water is the most contaminated. This makes the skimmer or surface water circulation (if applicable) an essential component to preventive maintenance. The powerful pull of the pump leads water into the filter; once dirt has been removed, it is heated, chemically treated, and returned to the pool through the returns.
Pool owners/operators should ensure the baskets inside the skimmers are cleaned regularly as part of a daily routine maintenance program. These baskets are used to catch debris on the surface while also protecting the pump. If the baskets are not cleaned regularly, they will become clogged with debris such as leaves, band aids, and other common waste found in pools.
This blockage will result in an additional ‘load’ being placed on the pump, forcing it to work harder to circulate the pool water and increasing the stress on the equipment.
CHECKS AND BALANCES
Physical pool care is integral to a maintenance program, but one should not discount the importance of water chemistry. Although it is not visible to the eye (in some cases), water care is a priority in any maintenance plan.
If there is an inconsistency in water treatment, there can be considerable consequences. When it comes to the chemical parameters that need to be monitored, they all have an impact; however, one of the most important and commonly neglected is calcium hardness. This water parameter measures the amount of dissolved calcium and magnesium in the pool to determine how hard or soft the water is. It is important to keep the calcium hardness balanced to prevent the water from becoming corrosive or cause scaling.
The nature of calcium hardness has massive ramifications if it is neglected, as the acidic component can impact the longevity of a pool’s structure and mechanical system. All municipalities have a different measure of source water, and because freshwater needs to be added daily, a good preventive maintenance program should include logs of routine water test results.
When the calcium hardness is low, it has an acidic effect on the system. Simply put, it is a form of acid that slowly eats away at the pool finish causing it to slowly deteriorate. This acidity can sometimes become lost in other chemical parameters, but can easily become the culprit if not checked and balanced regularly.
On the other end of the spectrum, when calcium hardness is high, scaling can occur and will be visible along the waterline tile. Behind the scenes, the calcium build-up will also be present in the plumbing. If the calcium hardness remains high for too long, it will eventually cause obstructions in the pool piping. This will cause closures and require costly mechanical retrofits to resolve the problem. This additional cost and inconvenience can be avoided by simply adding a calcium hardness check to the pool’s regular maintenance routine.
LEAVE IT TO THE EXPERTS
There are several components that impact the overall longevity of a pool and its operation; however, an experienced, knowledgeable technician will know the proper preventive measures required to ensure the pool system is running at peak performance.
Neglecting these well-known measures will inevitably impact the pool’s function; therefore, it is of utmost importance for an aquatic facility to not only have a preventative maintenance plan in place, but also ensure it is policed regularly to guarantee a safe and comfortable swimming experience for patrons
Knowledge is Power: The Benefits of Being a Certified Pool Operator
Wednesday, October 9, 2019
During the last several years, the aquatic industry has experienced a major growth. Innovative and continuously evolving technology has not only changed many of the physical attributes of aquatic centres today, but has also improved the overall swimming environment. With advanced operating techniques, tools, and maintenance practices, swimming pools have become safer, and more enjoyable to swimmers everywhere. However, without proper operation your patron’s safety and health as well as the longevity of your facility could be sacrificed. The training and education of your pools operators is crucial to the success of your facility.
LET'S BREAK IT DOWN
The Certified Pool Operators® (CPO®) course is an educational course provided by the National Swimming Pool Foundation® (NSPF®) that teaches students the fundamentals of pool and spa operation. After completing the course, participants will understand how to reduce risks, improve safety, and decrease liability for employers, facilities and patrons. CPO® certification courses are designed to provide individuals with the basic knowledge, techniques, and skills needed for pool and spa operation. The CPO® certification has provided training in the pool and spa industry since 1972, resulting in more than 350,000 certifications in 94 countries.
Who Should Be Certified?
Pool & Spa Operators
Facility Maintenance Staff
Environmental Health Officials
Facility Managers & Owners
The Certified Pool Operator program requires participation in either a two-day class taught by a certified instructor OR the blended format which combines the online, “Pool Operator Primer™”, and one day of the in-class instruction, “Pool Operator Fusion™”, along with a final examination.
This certification program includes:
Pool & Spa Chemistry
Chemical Feed & Control
Local and State Code Regulations
To complete the CPO® program successfully, participants are required to write an open book final exam and obtain a 75% or higher. Once completed, the certification is valid for five years and can be recertified with only a one day in-class review and exam by a certified instructor.
WHAT ARE THE BENEFITS?
This internationally accepted certification is a proven educational tool covering the necessary topics for pool & spa operators.
The comprehensive handbook is the perfect tool for participants attending the class, as well as an excellent source of reference for those who have completed the course.
All courses are taught by an NSPF certified instructor. This maintains the accuracy and consistency of the material.
The course provides participants with a better understanding of the operator’s role in pool and spa care, management, and risk reduction.
The CPO® course provides operators with a better understanding of the importance of water chemistry, which will result in a safer and more comfortable swimming environment, as well as improving the life of the facility.
The materials and topics covered in this course provide you with the essential knowledge to perform preventative maintenance and understand its impact on water purification and mechanical equipment.
The growth of the aquatic industry has created a demand for improved safety, and a higher level of education for the management of an aquatic facility. Although this course is internationally recognized, there are still those who have yet to become certified. It is imperative as an industry, that we encourage those who have not yet received certification, as well as those who have, to stay current and up-to-date on proper operation and maintenance of a safe swimming environment.
As the aquatic industry progresses, our aquatic professionals must also progress and improve. As they say…Knowledge Is Power!
Over the past several years, the aquatic industry has become more innovative, introducing owners and operators to new technologies and advancements which ultimately create opportunities to improve safety, increase longevity of the facility, and even provide energy savings. One of the advancements the aquatic industry has been very enthusiastic about is Variable Frequency Drives (VFD's).
WHAT IS A VFD?
A VFD is essentially a power conversion device. VFD's convert basic fixed-frequency and line power to a variable frequency and variable-voltage output which is used to control the speed of induction motors or pumps. Most VFD's are simple to install and are user friendly, however they are quite sophisticated in relation to their hardware and software operation.
The basic function of a VFD in the aquatic industry is to provide substantial energy savings. This is accomplished by controlling the speed of a pump rather than controlling flow through use of a throttling valve. Essentially, when you reduce the speed of a pump, you create energy savings. In addition to energy savings, the life of the impeller, bearing and seal is greatly improved which leads to longer lasting pumps.
BENEFITS OF USING A VFD
Saves money on energy consumption.
Maintenance costs are lower due to the lower operating speeds resulting in a longer life for bearings and motors.
A soft starter for the motor is no longer required.
Controlled ramp-up speed in a pool system can eliminate water hammer problems.
With a compact and modular design, VFD’s do not take up a lot of space.
Protect against system overloads, motor failures, motor and drive overheating, voltage disturbances, power surges, loss of phase, ground fault, overvoltage, over current, under voltage, external fault, over temperature, etc.
Minimize motor noise and heating with adjustable switching frequency modulation.
WHAT CAN'T A VFD DO?
Boost the output voltage significantly above the input voltage.
Increase the output power of the pump or motor.
Fix mechanical problems.
Variable Frequency Drives are a great addition to any pool equipment room whether it’s new or existing. Not only do they save owners and pool operators on the costs associated with high energy consumption, but they also increase the longevity of the pumps and motors. VFD’s are available in different sizes (HP) and voltage requirements.
As the temperatures begin to drop, the realization that the end of the summer season is approaching sets in. While the colder weather looms in the near distance, our to-do lists grow significantly as we scramble to get all of our summer equipment stored away before it gets too cold. Since most residential, commercial outdoor pools and splash pads close after Labour Day weekend in Canada, closing the pool usually tops the list for pool owners and operators.
For residential pools especially, did you know that it is best to keep your pool open until the water temperature is consistently below 15 degrees Celsius (59 degrees Fahrenheit)? This allows the water to be a consistently lower temperature which creates a better environment for closing chemicals, ensuring they last until spring.
For commercial pools and splash pads it’s a completely different world. Most large commercial pools are required to be fully drained in order to plug up all of the main drains and ensure all of the systems are completely empty.
Tip! Before winterizing, chemically treat your filtration system. Contact your pool experts to find out how to remove grease and oil from your filters to increase their lifespan and save money for next season!
Use the checklist below as a guideline for closing your outdoor pool.
Remove deck equipment, hardware, and non-permanent objects such as ladders, rails, tot slides, guard chairs, starting blocks, drinking fountains, accessibility lifts, portable ramps, clocks, weirs, and safety equipment to prevent vandalism. Store in a clearly marked, identifiable, weather- protected location. Cap all exposed deck sockets.
Remove the diving boards and store them indoors (upside down and flat to prevent warping).
Follow your manufactures directions for the winterization of any toys and water features in your facility. Some smaller units can be removed, while others, like dumping buckets, remain and have specific procedures to follow for winterizing.
Tip! Isolate your flow cell for your probes before you drain your system.
Completely drain the pool and remove all white goods and skimmer baskets and store in a marked container. Residential Pools only need to be drained down to 1 ½’ below the returns and discharge the lines.
Drain all of the pool equipment including pumps, strainers, heater, UV systems, filters, surge tanks and holding tanks.
Store all probes from chemical controllers in water in a warm environment for the winter months. Do not allow the water to freeze.
Using an air compressor and correct connections, discharge the main drains, skimmer/gutter lines, returns and jets from the mechanical room to the pool.
Plug all of the lines on the pool side with the proper sized fitting or test plugs. Consult your pool specialist for assistance if you need to replace any threaded or test plugs.
Fill your pumps or strainers with pool grade antifreeze to keep the mechanical seals lubricated for the winter. This will ensure a smooth start up in the spring.
Fill the pool for the winter to your recommended depth based on your specific pools requirements. If you're unsure about your facility's requirements, contact your pool consultant or design engineer.
Install pool covers if required in your area.
Turn off the water supply and restroom showers, sinks, and toilets.
Drain all of the pipes to ensure all of the lines are free of water. Remove shower heads and drinking fountain handles.
Open hose bibs and fill spouts.
Have your phone service provider disconnect the pool telephone and discontinue service for the winter season.
Confirm the security of the facility to present unauthorized access.
Ensuring you have winterized properly can be a worrisome, but with the right preparation beforehand and ensuring you have the proper tools, you will be ready. Before you know it, Spring will be upon us and it will be time to open again!
It's that time of year again, the birds are chirping the sun is shining and the snow and frost are behind us. When this happens, professionals in both the commercial and residential aquatic world think of one thing...let’s open the pool!
With the warm April weather, the opening season is underway and in full swing. Are you ready to open your facility's outdoor swimming pool? Many of us made lists last winter with the best of intentions, but as with most things in life, those lists still stare us in the face. So here we are. It's time to finally tackle that list and get your pool open for the summer season!
One of the best strategies is to prepare an opening checklist to ensure your hard work doesn't come to a hault when you find you are missing pieces or in need of parts. Check out our sample checklist below.
Take inventory of all the operational parts like jets, return fitting, weirs etc. (in the pool industry we refer to these as “white goods”).
Ensure your flow meters, pressure and vacuum gauges, and o-rings are ready for opening day.
If during inventory, you find missing or find broken pieces, have them replaced and ready for installation.
Once your inventory is complete, ensure all of the necessary replacement pieces are ordered and ready to go on opening day!
"Did I winterize my outdoor swimming pool properly?" is the biggest worry every pool owner or operator has in the spring. Mother nature can be cruel, unpredictable and a powerful force over the winter, but most of the time it is out of our hands. Performing a walk around and checking the deck and pool area for visible damage and/or vandalism is the first step. Once your visual is done you can start your true opening procedures.
"Don't forget to order and check stock of all your chemicals for start-up and season opening."
Once your inventory check is complete, you've done a thorough walk around and you've ensured your chlorine delivery is ready to go, it's time to start opening your pool. If you're working on a commercial outdoor pool, drain out any of that dirty winter water with a submersible pump and use a power wash to clean up the walls and floor.
Remove any winterizing plugs in the main drains, returns and jets. Ensure that the hydrostats in the main drains are clean and working properly.
Reinstall drain covers and perform an inspection to ensure there is no broken, worn or dated pieces. If you find any areas of concern, consult your pool professional for immediate replacement.
Once everything is clean and shiny in the pool area, move onto the mechanical room. Ensure all the equipment is back together, and all of the o-rings on the pump and strainer lids are lubricated and ready to start.
Now that the pool is full and glistening in the sun and ready for start-up, run through all of your valves and ensure they are in proper operating positioning.
"Always start up the system on backwash. This will ensure that all of the left over sitting debris from the winter goes out to waste and not back into your beautiful swimming pool. Once a complete backwash is finished, start up on filter mode."
Your next task is getting the balancing done and ensuring your stabilizer levels are ready to help battle the hot summer sun and keep your operation costs down.
"Stabilizer is sunscreen for chlorine."
Now that the pool is operating and the water features are flowing, you can sit back, close your eyes and visualize the upcoming summer season.
The Ontario and other provincial Building Codes have minimum standards that have been established to ensure that new public pools are constructed to be safe and functional. Following construction, Health Departments are responsible for monitoring and regulating the operation of the pool. The entire content of the code is important, but some items really stand out. For example, strict adherence to the velocity of water moving through suction fittings like the main drains is really important. The velocity of water through main drains is dictated as not to exceed 1.5 fps (feet per second). This low velocity helps decrease the possibility that people might become entrapped or entangled by the main drain fitting.
Another really important factor is the turnover rate of the pool. For Class ‘A’ pools (a pool to which the general public is admitted), the entire volume of the pool has to be filtered and chemically treated every four hours. This ‘turnover rate’ provides some assurance that the pool water will be clean and safe for bathers to use. The Building and Health Codes are very important and have elements that work to ensure pools work really well and up to standards, most of the time. As with most rules, there are some exceptions that should be considered. An important question to consider is: When is it a good idea to do more than what the code calls for?
CLASS A & CLASS B POOLS
In Ontario for example, a Class ‘B’ pool (a pool operated on the premises of an apartment building with five or more units, a pool operated as a facility to serve a community of more than five single-family private residences, a pool operated on the premises of a hotel, a pool operated on the premises of a campground, a pool operated in conjunction with, a club or a condominium, a pool operated in conjunction with a day nursery, a day camp or an establishment for the care or treatment of persons who are ill, infirm or aged) is required to be designed in such a way that the circulation system exchanges the entire volume of the pools water once every six hours, or four times per day. Most of the time, this is totally acceptable, but there are times when it is not sufficient. At some resorts for example, the pools are shallow and the volume of water is small. This coupled with a very high usage, warmer water and bathers who may not shower as well as they should (especially children) can create a condition that makes the water quality very difficult to manage. We often oversize the circulation systems with larger than required pumps and filters in this instance and add secondary sanitation systems like UV to help ensure superior water quality.
The same is true of a Class ‘A’ pool. These pools are required to be designed to exchange the water in the pools every four hours or six times per day which seems like a lot, but again there are some exceptions. If the pool is a therapeutic pool with a higher percentage of elderly users, or users with either a physical or mental disability, there may be a higher risk of contamination by fouling, making it prudent to exchange the water more often and install UV systems. For pools like this we often design the mechanical system to exchange the water every two hours, or 12 times per day, or more.
Another important consideration is the filtration rate of the pool filter system. In all cases this is calculated by dividing the total flow of the circulation pump by the total surface area of the pool and is expressed as GPM/FT2 of filter area. For sand filters, most manufacturers call for a filtration rate of no more than 15 GPM/ FT2. For a pool that has a flow rate of 450 GPM, the total sand area should be no less than 450 GPM/ 15 GPM/FT2 = 30 FT2. This square footage can be achieved by either using one or two larger horizontal or vertical filters, or a ‘battery’ of smaller filters. Is a filtration rate of 15 GPM/ ft2 always enough? For a lesser-used pool with a lower-risk user, and a low bather load, the answer is probably yes, but in instances where there is a high bather load, it may make sense to lower the velocity of water through the filter to improve filtration even more. Sometimes it makes sense to oversize the filter so that the filtration rate is more like 12 GPM/ft2. The same thing can be done with other filter media like cartridge filters or DE (diatomaceous earth) filters.
UV SANITATION SYSTEMS
UV is a secondary sanitizer that effectively renders most bacteria unproductive (and therefore safe) as water passes through the device. UV units are not required by code for pools (UV is required for splash pads) or spas, but may be a really good idea to install anyway. Some bacteria are resistant to chlorine or bromine and can become the source of an infectious condition that can make swimmers sick. This can result in a severe and widespread illness outbreak that could have long term effects or even cause the death of a vulnerable individual. There could also be legal implications for the owner/operator of the pool. Even though the codes do not require it, putting UV systems on a high bather load or high risk pool is a smart and proactive change to make.
Finally, the codes are an effective way to improve the overall safety of pools across the community. As with all rules and regulations, not every scenario can be addressed. It is best to look at the particular conditions surrounding your pool and design it appropriately. Since there is no specific ‘rule book’ to help you decide when code requirements should be exceeded, it is best to consult an aquatic consultant or pool builder who has a long record of experience with a variety of public and private pools. These experienced companies will help you design, build or upgrade a pool that is safe and fun for your clientele.
Dive Stands are a great addition to any facility, but of course have inherent dangers and cost a lot of money to replace. Let’s talk about how you can make your dive stand and spring board as safe as possible, and how to protect your investment!
DON'T SLIP UP
The lifeguard staff should check the surface of the springboard to be sufficiently “non-skid” at the beginning of every shift. This should be done with the board wet, to simulate what it is like when in use. If the board is found to be slippery, it should be taken out of service until the issue is resolved. Nobody want to see anyone hurt or to suffer any legal consequences. The owners, supervisors and lifeguard staff could all potentially share a liability if the board were subsequently shown to be unfit for use.
What is in the Making of a Slip?
There are a few reasons that boards can become slippery:
Dirt and body oil from swimmers and sunbathers can collect on the surface of the board, making it slippery just because of the nature of the material (oils) or by filling in the ‘voids’ of the textured surface so that it effectively becomes smoother and therefore more slippery.
Excessive alkalinity or minerals in the water can cause scaling that again renders the textured board smoother, or damages the textured surface.
Wearing, releasing or damage of the textured surface.
How do I Prevent the Board from Becoming Slippery?
Hose the board down with fresh water (not pool water) every day. This will help keep the textured surface free of contamination. Never use a high pressure washer for this; you will shorten the life of the texture by blasting away the aggregate.
Once a month, give the board a good scrubbing wash with a detergent and hot water. This will remove oils and keep the texture in good shape. Always use a soft bristle brush - never stiff.
If there is a hardness buildup, a muriatic acid solution can be used to dissolve the minerals. Remember to exercise all appropriate safety procedures when using muriatic acid!
The Textured Surface is Gone…Now What?
Take the board out of service. It just isn’t worth the risk of continuing to use it. Most commercial manufacturers offer refinishing of commercial boards. Contact your commercial aquatics provider, and they will help arrange shipping and refinishing of your board so it is like new, and back in tr-action!
The manufacturers use a special epoxy to bond the slip resistant material to the board, and the material itself is designed to reduce surface tension so that water doesn’t stand tall on the board. Don’t try to resurface the board yourself. It won’t be as good as the factory does it, and you accept the liability if there is an accident after you put it back into service.
OK…What Else for the Board?
The rubber channels on the underside of the board must be inspected monthly for signs of wear. If they are getting close to being worn out, they should be replaced BEFORE the metal ridges on the underside of the board come into contact with the fulcrum. If left unchecked, the fulcrum AND the board will be damaged!
That’s Great for the Board, but What About the Stand?
The best and easiest thing to do is to rinse the entire stand with clean water at the beginning and end of every day. This is especially important for indoor pools. When the stand cools off at night, warm humid air will condense on the stand and handrails, leaving a chlorine residue on the equipment and cause it to degrade prematurely.
Keep the fulcrum components clean, especially the tracks.
Keep the roller clamp lock nuts, and anti-rattle lock nuts, snug and adjusted for a "no-rattle" clearance.
The two grease fittings of the roller block should be lubricated every 2 weeks. Use "Mystic JT-6" grease and grease gun.
The hinges that hold the board to the stand need 2 drops of oil every 2 weeks. Use lightweight oil as for door hinges.
The carriage bolts that attach the diving board to the hinges should be checked for tightness periodically. The carriage bolt nuts need to be maintained at 110 lbs of torque (You’ll need a small torque wrench to do it properly).
Check all handrail and assembly bolts as part of a quarterly preventative maintenance program to keep everything up to snuff.
The stainless steel components are 304 stainless, which is a good quality material for swimming pool natatoriums, but like all stainless steel is not ‘rust-proof’. If rust does appear:
Clean it immediately with stainless steel cleaner and a cloth.
Rinse with lots of fresh water (never pool water).
Using an anodizing product or even wax as a barrier will help prevent future rust.
Air quality is critical to the prevention of rust on metal components. Good air handling equipment or the addition of a UV system to the pool go a long way toward improving air quality by reducing airborne chloramines.
2 Resolutions that will Improve Your Aquatic Facility
Wednesday, January 16, 2019
January is the month of resolutions. We plan to live a healthier lifestyle, be more financially responsible, and visit with friends and family more often (among others). But what about our aquatic facilities? Improving safety and becoming more environmentally friendly are two resolutions that your facility can make this and every year. The following are ways that your facility can do both:
PLAY IT SAFE
Safety should always be the highest priority at any facility. Improvements can always be made to increase the safety of your pool staff and patrons.
Stay up to date on new changes in codes and policies.
Ensure your staff is equipped and trained on the proper regulations and requirements.
Train your staff (pool managers, lifeguards, operators etc.) in the basics of commercial pool operating and general swimming pool knowledge. This includes chemical testing, accident prevention and the emergency protocols used at your facility.
Ensure all of your staff remains current and up-to-date in all required training (CPR, first aid, CPO etc.)
Inspect all of your safety equipment and keep an up-to-date inventory throughout the year. Safety and pool equipment can age, rust, and become damaged over time. It’s important to be aware of any equipment that needs to be replaced before an accident occurs. Equipment can include first aid kits, spine boards, life rings, safety rope, fire extinguishers, warning signs, deck equipment.
Perform an annual slide inspection. As water slides age they can rust, or become damaged. It is necessary to have a licensed water slide technician inspect the slide to protect and ensure the safety of the users.
When changes are made at your aquatic facility, it is important to update your staff. This includes pool managers, operators, lifeguards, aquatic instructors and anyone else who works in the aquatic centre.
KEEP IT GREEN
Today, everyone seems to be going green in some way. The importance in becoming environmentally friendly has shifted the way we live our lives, and the way we conduct business each day. Not only does going green provide environmental benefits, but green efforts can also lower your operating costs.
Make the switch to environmentally friendly products and replace old equipment with new, energy efficient equipment. This solution will not only improve your facilities impact on the environment, but will also benefit your budget.
Installing a Variable Frequency Drive (I-Pool VFD) can save you $7,000 - $10,000 a year.
Installing an Ultraviolet System decreases chemical usage by 20%.
Reduce chemical use at your facility. Water that is maintained properly and consistently can lessen pool water issues and chemical treatments.
Use an environmentally friendly liquid “pool cover” to decrease chemical usage and save on operating costs by reducing evaporation and heat loss.
Repair any existing leaks and service balance tanks to ensure they are operating properly.
What is Ultraviolet (UV) & How it is Applied to Swimming Pools?
Wednesday, November 21, 2018
The strong smell of chlorine within an aquatic facility is not a sign that the pool or spa is clean. It's actually a signal that there is something wrong. Luckily, there is an application that can be added to your swimming pool recirculation system to help correct this issue, and create a safer and more enjoyable swimming experience - An Ultraviolet (UV) system.
From a hydrotherapy spa to the largest Olympic-sized competition pool, UV sanitation systems are quickly becoming (or have already become, in some municipalities) the most popular method of additional water treatment in the aquatic industry. UV not only destroys chloramines, the unpleasant by-products of chlorination, but it is also a highly effective disinfectant (although the need for chlorine is reduced with the use of a UV system, it is still needed to ensure proper disinfection).
Chloramines are formed when free chlorine reacts with sweat, urine, and other contaminants in pool water. Trichloramines, in particular, are powerful irritants which are responsible for eye and respiratory complaints and the unpleasant ‘chlorine smell’ commonly associated with indoor pools. Chloramines are also corrosive to the surrounding area, and in time can lead to damage to pool accessories, buildings and structures, such as railings, ladders, and ventilation ducts. Any water treatment system that reduces these unwanted conditions is therefore welcome.
UV harnesses the power of ultraviolet light to eliminate microorganisms, lower chemical usage, and eliminate toxic by-products.
WHAT IS UV?
UV is a highly efficient, natural disinfectant that nutralizes virtually all known microorganisms, including bacteria, viruses, and molds and their spores, by permanently destroying their DNA.
Ultraviolet light is a naturally occurring component of sunlight. It falls in the region between visible light and X-ray in the electromagnetic spectrum. The mechanism of UV disinfection is strong sunlight that disinfects water by permanently de-activating bacteria, spores, moulds and viruses.
These systems reproduce UV radiation inside light chambers via powerful lamps, which emit germicidal UV-C light that is used to disinfect pool and spa water.
UV-C causes permanent damage to a number of microorganisms almost instantly as the water circulates through the light chamber. By disrupting the microorganism’s DNA, protozoans, viruses and bacteria are unable to replicate and remain inert. This light, however, works only on water that flows through the chamber.
HOW IS UV APPLIED TO SWIMMING POOLS?
Ultraviolet is a recommended application that can be added to any swimming pool. However, it should only be used as a secondary pool water disinfectant. A primary disinfectant, such as chlorine or bromine, still needs to be used at all times. Chlorine/bromine have a very important property which UV lacks – the ability to provide a residual level of disinfectant in the pool water contained within the tank itself. This means chlorine/bromine can remain in the pool water actively attacking pathogens at the moment they are introduced, whereas a UV system can only disinfect the water that passes through the UV chamber within the pools recirculation system. Once the water has left the chamber, it is vulnerable to be re-infected by swimmers.
UV systems are particularly suited to both chloramine destruction and disinfection. The resulting effect is a cleaner, healthier, and more pleasant atmosphere both in and around the pool. The potential dangers caused by Trichloramines are significantly reduced, and the danger of infection by harmful microorganisms is also eliminated.
There are a variety of considerations to be taken into account when choosing an Ultra Violet system and different lamps are used in different applications. The nature of the decision can be quite detailed, making it important to find the right swimming pool professional who can assist in finding the right application for you and your aquatic facility.
