Guide to Pool Closing

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!

High In The Sky

In today's world swimming pools are all around us. Who doesn’t have a pool in their backyard or have a close neighbour with one? Friends and family gather around them, making wonderful memories every day. Fitness clubs have pools, community centres have pools, hotels have pools, and now high rises in the sky even have them. Building a residential or commercial pool on the ground level is a relatively easy task, but what are the challenges of building an elevated pool high in the sky?

 

CONSIDERATIONS

When building in a high rise structure, several considerations need to be taken into account during design. Keep in mind a 4 foot deep lap pool that is 75 feet long holds approximately 75,000 gallons of water. Water weighs 8.34 pounds per US gallon, equating to 625,500 pounds of water - and that’s just the weight of the water! Add in the weight of the concrete pool shell, reinforcing steel, interior finishes and mechanical items and it doesn’t take long for a small lap pool to weigh in excess of 900,000 pounds. That’s a lot of additional weight on a building structure or roof top. Structural engineers and architects have their work cut out for them to design and engineer a building structure that’s safe enough to hold all of this additional weight.

 

 

One other consideration when designing a swimming pool in an elevated structure is waterproofing and sealing of the structure. Nobody wants 75,000 gallons of water leaking out into a building and running down into the main lobby. Today’s swimming pools have cantilevered edges that hang out over the edge of buildings, windows in the walls, and in some cases glass bottoms. Providing a positive seal in extreme building conditions such as this can be a challenge. Engineers spend countless hours running calculations to provide 100% watertight designs.

 

Aside from the structural and waterproofing challenges outlined above during design, now there is the challenge of building it. Countless men and women climb story after story of stairs or ride construction elevators 10, 20, even 50 stories up to start construction of these wonderful and challenging pools high in the sky. Hundreds of cubic meters of concrete need to be pumped up, or craned up sometimes hundreds of feet to be poured in place. Thousands of pounds of structural reinforcing steel and mechanical equipment need to be hoisted in place by tower cranes and snaked through the building structure to be constructed in place. Every move in this elevated construction environment needs to have several hours or even days of planning. On the ground it's easy, back up the cement truck and start pouring. When you're 50 stories in the air, it’s a little more challenging. 

 

 

So the next time you visit a luxury hotel or you're at a resort on your next vacation check out the roof top swimming pool. Challenge yourself to swim out over the cantilevered edge and imagine the challenges of constructing that beautiful masterpiece.

 

Fun Fact: Some elevated swimming pools in high rise buildings are used to protect the building structure in event of a fire. Some of these pools have a connection so the fire department can quickly pump water out of the pool in the event of a building fire.

Family Friendly Pool Toys

Your swimming pool can be a wonderland of fun and adventure. With the new and classic choices available, you have the ability to change the atmosphere from day to day simply by using different water toys. As a child growing up with a pool, nothing was more exciting than going to the pool store and looking at the new trendy toys. The options available today would blow my younger self’s mind.

 

POOL SPORTS

 

Pool sports and games are great fun for family and friends. A volley ball net allows for a large group to come together and play. With the ability to rotate in and out of the game, everybody of all age groups gets a chance to play. If you are looking for a more competitive game, poolside basketball and water polo nets are great options. There are even multi-use systems that combine games like volleyball and basketball. A cost-effective way to add more variety to your sport options.

 

INFLATABLE POOL TOYS

 

Todays inflatable toys have come a long way from what the options available when I was a kid. If you wish to relax and have some time for yourself, there is a limitless selection of mattresses, tubes, boats, themed floats, and lounges. Many inflatables have added games into the design, like Pongo Bongo or have built in water guns to turn your inflatable into an afternoon of competitive fun. Larger inflatable lounges and couches that can accommodate up to six people are also available - complete with built in coolers and cup holders. What a fantastic way to spend a lazy Sunday with friends! Options for little ones have expanded as well. The classic water wings are always available, along with a variety of floating seats with sun umbrellas, larger inflatable islands, play structures, wheels, slides and more - the choices are endless!

 

DIVE TOYS

 

Pool toys can keep young ones (and even the young at heart) busy for days on end. Dive toys are available in a variety of shapes and sizes, allowing young swimmers to use their imagination to create new challenges. Also available, the “Aqua-Zooka” can shoot up to 50 feet and turn a regular water fight into a no holds barred battle.  It’s amazing that no matter how old you get, soaking somebody with a water gun is still a blast!

 

AQUATIC EXERCISE

 

Aquatic Exercise has become popular as a low impact fitness approach. The ability to swim with a deck mount tether or deck mount flow generator gives you the benefits of long distance swimming without the need for an Olympic sized pool. If aquatic exercise is what you enjoy, there's even treadmills and stationary bikes designed for use in pools. This is a terrific way to get the exercise without the hard impact on your joints and back. Foam weights are another amazing way to exercise by allowing buoyancy to create the desired resistance without the heavy impact of regular weights.

 

When it comes to choosing the best water toy for you and your family, the sky is the limit. The best part? You can choose more than one!

Guide to Pool Opening

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.

Meeting & Surpassing Code Requirements

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.

 

FILTRATION RATE

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 Stand Manitenance

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.

Remembering Virginia Graeme Baker

Most pool owners and operators have heard the term VGB compliant as it relates to main drains in swimming pools, and may have heard of the Virginia Graeme Baker Pool and Spa Safety Act that was brought into legislation in the United States.

 

As a member of her community swim and diving team, Virginia Graeme Baker was a strong swimmer who could swim unassisted at only 3 years old. Despite this, Virginia (called Graeme by her family) died in a spa (hot tub) after becoming trapped on the single main drain fitting of the spa, even with the frantic efforts of her mother, Nancy Baker to release her from the drain. Eventually, two men were able to release Graeme from the drain, but exerted so much force that the main drain fitting was actually broken in the process. At the very young age of 7 years, Virginia Graeme Baker died from drowning as a result of becoming entrapped on the main drain fitting of the spa.

 

MAIN DRAINS & THE RISKS

The danger of a single main drain in a pool or spa cannot be overstated; when a single main drain is covered and is the sole source of suction for a pump, a tremendous hold-down force is exerted on the person covering the main drain fitting. For a typical residential pool or spa with an 8” round drain, the hold-down force can be in the order of 739 pounds! Even the strongest person would be unable to overcome this kind of force. The larger the surface area of the drain the greater the force, even if the same pump is used. For a 9”x9” main drain, the force will be about 1191 pounds, and for a 12” x 12” main drain the force will be a whopping 2117 pounds! This is approximately the same weight as a skidof bricks! But becoming entrapped by the suction is only one of the dangers of an improper drain installation. People can also become eviscerated if they sit on an improper drain, or become entangled (hair and jewelry) if the velocity of water through the drain is too high, or the drain openings are improperly designed.

 

PREVENTION

Following Graeme’s death, Nancy Baker worked tirelessly as an advocate for pool safety and through the political clout of her father-in-law, former Secretary of State,  James Baker III, and in association with Safe Kids Worldwide, lobbies to congress to bring into law the mandatory use of anti-entrapment drain covers and other safety devices and methods.

 

Use VGB Compliant Main Drain Covers

Perhaps the most important change was the nature of the drain cover itself. Main drain covers are now required to be VGB compliant, meaning that they have a shape and openings that have been designed to dramatically decrease the likelihood of a person becoming entrapped. The drains are also sized for different flow rates so that the velocity of water moving through the surface of the grate does not exceed 1.5 feet per second. This low velocity decreases the likelihood that things like hair will be drawn into the grate creating an entanglement problem.

 

Use Multiple Main Drains

Another important safety measure in pools and spas is to never have a single main drain. In Canada,  it is law that every public pool and spa have at least two main drains, and that these be spaced apart from each other by at least four feet (1.2m). If one drain fitting is blocked, the water has another path to go though (the other drain fitting) so that an ‘absolute’ vacuum cannot be achieved.

 

Use a Safety Vacuum Release System

Finally, another measure to improve main drain safety is the use of Safety Vacuum Release Systems (SVRS). These devices are installed on the suction side of the pump(s) and are designed to eliminate the suction force of the pump. There are generally two types (mechanical and electrical) which are designed to sense excessive suction and act to relieve this suction. Electrical units work by shutting of the pump, and mechanical systems work by allowing air to enter the pump so that it loses suction.

 

Swimming pools and spas provide a tremendous amount of fun, leisure, exercise and therapeutic benefits to families, the public and patients. But we have to always remember that pools are really machines designed for our aquatic needs, and like all machines, pools have inherent dangers that have to be managed. For decades, we drove cars without the benefit of seatbelts, airbags and so many other safety features. At one time, we didn’t even have windshield wipers! Thanks to the efforts of Mrs. Baker after her loss of Graeme, properly designed pools and spas are now safer than they have ever been.

Transform Your Facility into a Multi-Use Facility

Movable floors and bulkheads are becoming more common in aquatic facilities throughout North America. Although they offer similar benefits to an aquatic centre, there is a big difference between the two options.

 

MOVABLE FLOORS

Movable floors change the depth of the swimming pool water, while bulkheads act as a divider in the pool. Adding a movable floor and/or bulkhead will create endless opportunities for many different programs and activities within one body of water. Imagine the difference a movable floor or bulkhead could make in your swimming pool!

 

With a movable floor system the programming opportunities at your aquatic centre expand; traditionally you would need numerous bodies of water to offer these types of programming:

  • Swimming lessons (0.5M-1.2M)
  • Lane Swim (1.1M-1.35M)
  • Diving (3.0M-5.0M)
  • Synchronized Swimming (2.0M-3.0M)
  • Water Polo (1.8M minimum)
  • AquaFit (1.2M-1.5M)
  • Aqua Cycle (1.0M-1.2M)
  • Water Walking Programs (1.2M-1.5M)
  • Physical Rehabilitation (Beach entry or 0.5M-1.5M)
  • Competition Training (1.2M-1.5M)

 

The photo above shows the movable floor at the new Guildford Recreation Centre in Surrey, B.C where the water depth changes several times a day in order to accommodate various programs at the facility.

 

BULKHEADS

The addition of a bulkhead at your facility can allow you to accommodate many different programs and activities individually or simultaneously! Large, single activity pools can be divided easily to create separate swimming areas for:

  • Swimming lessons, fitness programs and other aquatic classes
  • Swimming competitions, water polo competitions and other sports events
  • Diving and synchronized swimming
  • Other special aquatic programs

 

The photo above shows the bulkhead installation in action at the Roosevelt Park Pool in Rapid City, South Dakota. The facility includes a 10-lane, 50M outdoor pool and when the Bulkhead is in the middle park position, the pool transforms into a 20-lane pool! This pool also features water polo courses for both men and women.

 

MAKE THE RIGHT CHOICE

When choosing a movable floor or bulkhead manufacturer, it is important to consider the following:

  • What is the installation time and complexity of the bulkhead/movable floor?
  • Is the operation of the bulkhead/movable floor easy and user-friendly?
  • Are the maintenance and service costs low?
  • Are the metal parts made of non-corrosive 316 stainless steel or special bronze?
  • Does the bulkhead/movable floor offer an aesthetically pleasing appearance?

Movable floors and bulkheads offer the ultimate aquatic versatility for your facility. The addition of a movable floor to a swimming pool can make it simultaneously a deep diving pool, a child friendly shallow depth pool or a mid-depth pool for exercise and water games. The addition of a bulkhead can transform a large single activity pool into separate swimming areas for classes, sports events, or special activities. Installing a movable floor or bulkhead will increase water usage and maximize the swimming pools potential. One pool with unlimited possibilities!
