Fix A Leak for Pool and Spa Leaks

Fix A Leak seals pool leaks and spa leaks.

Fix A Leak
Available in two sizes

32-ounce (954 ml.)

8-ounce (120 ml.)

The Fix A Leak formulation is a patented, concentrated, blended composition, that seals pool, spa, swim spa or hot tub leaks, in materials of all types. Helps seal leaks in the walls, floor, shell, return lines, suction lines, skimmers, fittings and more. This product helps make long-lasting seals, in holes or defects, up to 1/8" in diameter (3 mm) in size. Pool dosage is 1-quart (954 ml.) for up to 22,000 gallons or 83,600 liters. Spa or Hot tub dosage is 4-ounces (120 ml.) per 250 gallons or 950 liters. Larger units should use proportionally greater quantities. Leak detection services can be expensive and can result costly repair efforts and damage to the surrounding area. Using Fix A Leak is a non-invasive way to help seal small leaks. As water containing, Fix A Leak, seeps out of the leak, it starts to form a crust, on the outside of the defective area. After the crust forms, stopping the leak, it must completely dry out, in order to harden and cure, forming a long-lasting seal. The curing process usually requires about 2-4 days. The cured crust will be on the outside of the pipe, wall or fitting. The product has been tested under different weather conditions and has been proven to be an effective leak sealer. It is not recommended for leaks that lose over 2-inches of water daily. However, it certainly makes worthwhile sense, to try Fix A Leak, in situations where water losses are less than 2-inches (5-cm) per day, especially, considering the cost and possible resulting damage of standard repair methods.  FIX A LEAK is the genuine article and has been dedicated to pool and spa leak repair since 1980. Directions are spelled out step-by-step.  Fix a Leak is the original and best. Insist on the Original and Genuine Product: Fix A Leak.

Fix A Leak has been used to seal pool and spa leaks, for more than 35 years.  In addition, this versatile product has been successfully used to seal leaks in geothermal applications, fountains, water features. stone roofs and more.

Available, by the case, for professional use.

General Directions for using Fix-A-Leak Sealant

Read the directions, before attempting use.  Shake Well Before Using!!!

Fix A Leak is not always used, in the same manner.  Suction line leaks require different instructions:  scroll down to the next section.  Fix A Leak stops small leaks, by forming a crust, as water containing the product seeps out of the leak.  Because Fix A Leak is heavy it will sink to the bottom.  To help keep the product in suspension, so that it can get carried to the leak site, you need to operate the pump and brush the floor, for periods throughout the day.  The pump can be operated 24/7, as that can help deliver the Fix A Leak, to where it is needed.  Once the leaking has stopped, this crust must dry and cure, in order to form a long-lasting seal.  Mark the water level, before starting, so that y6ou are able to monitor the progress.  Once the leaking has stopped, you can resume normal filtering.  For best results, use as directed below.

Bypass the filter, before adding the pool and spa leak sealer to water. Sand filters: set filter valve to recirculate. Other types: remove cartridges or DE elements from filter tank and proceed to circulate through the empty filter tank.

With the pump running, add the product slowly through a skimmer or in front of any other suction intake.

After adding FIX-A-LEAK, adjust suction to 100% main drain. If this is not possible, a pool vacuum could be used alternatively, simply by placing the vacuum in deepest part of pool and connecting, in the usual manner. Set filter valve to normal vacuum position.

This leak sealer is very heavy and will sink to the deepest point quite quickly. It must be stirred back into suspension, either manually using a pool broom or mechanically with an automated pool cleaner, every 4-6 hours, while maintaining circulation of water. Continue to recirculate water, until the leak has stopped.

Mark level of water in pool and check for 2-3 days, in order to determine, if the pool or spa leak has stopped.

After the leak has stopped and given the proper time to cure (24-72 hours), you may return to normal filtration. Proper curing requires that the Fix A Leak be allowed to completely dry out, where it has formed a crust at the leak site, as it seeped out. This leak-sealing crust forms on the outside of the pool, spa shell or pipes.  Draining of the pool or spa is not necessary.  The excess Fix A Leak will be removed, with the resumption of normal filtration and the vacuuming and/or brushing of the pool or spa floor.  Sand Filters: set valve to filter and resume normal operation. Backwash out unused Fix A Leak, as required. Other Types: reinstall filter into tank and resume operation. Rinse out unused product from filter, as required.

Never let cartridges of DE elements be left to dry before they are cleaned.

If you have an inline Salt Chlorinators for Pools or Salt Chlorinator for Spas, ultraviolet sterilizer or ionizer, the standard instructions should be followed, without any modifications.

For best results, the Pool or spa water temperature should be at least 70░F (21░C).

Bathing can resume, after the excess Fix A Leak is removed, by filtering and vacuuming and the water chemistry has been optimized.

reatment can be repeated, if necessary.

Suction Line Leaks

A leak in a suction line is usually characterized by seeing considerable amounts of air bubbles, in the return flow. A few bubbles may not indicate a leak problems, as would water described as being aerated.

If a suction link leak is present, water will not leak out while the pump is running, because air is being sucked in. However, once the pump is switched off, water can start to leak out. With air being sucked in, there is no way that Fix A Leak will be able to work.  To perform properly, it must be able to seep out and start crust formation. The flow of water must be reversed. There is no valve setting that can accomplish this. This is not always simple. The filter must be bypassed, as in the previous section. Once the flow has been reversed, by physically switching the lines going in and out of the pump, continue to circulate the water at 5-10 PSI.  Frequently brush the floor, for the next 3-4 days. You can restore normal filtration, only after the leak has been stopped for at least 2-4 days or you are certain that the leak area has completely dried out.

Once normal filtration has been resumed, you must remove the excess Fix A Leak product, as outlined, in the section above.

Miscellaneous Pool or Spa Leaks

If the pool or spa is suspected to be around a fitting, such as return jets, lights, skimmers or steps, shut down the pump.  Leak detection dyes are available, which can be used to help trace the way to a leak.  The concentrated dye is added, using only a few drops, near the potential leak site.  The water must be still.  Watch the dye disperse and see, if it is drawn to a particular spot or area.  That most likely is where the problem is located.

Shake the Fix A Leak well and pour some into a dispensing bottle, such as used for mustard or ketchup.  Apply the Fix A Leak product, to the suspected leak site, by slowly squeezing out small amounts. If the leaking appears to stop, wait 2-3 days, before starting filtration, in order to minimize potential vibration.

Leaks can be subject to expansion or heavy vibration, such as cracks or loose fittings.  Fix A Leak may
not posilutely and absotively seal every type of pool or spa leak. Any leak larger than 1/8" (3 mm.) in diameter, may simple be too large to be sealed in this manner.  Daily water losses greater than 2" (5 cm.) per day may involve water flow, that is too great to allow for proper crust formation and curing.  However, it certainly makes worthwhile sense, to try Fix A Leak, where losses are less than 2-inches (5 cm.) per day, considering the expense and restoration efforts, required with standard repair techniques.  
Fix A Leak is the genuine article, specializing in pool and spa leak repair since 1980.


Spa or Hot Tub Leaks

Remove cartridge filter, which effectively bypasses the filter.  If you have a sand or D.E. filter, refer to the General Directions section.

Dosage rate is 4-ounces (120 ml.) per 250 gallons (950 ml.).  Fix A Leak is quite heavy and will settle to the spa floor very quickly. Shake well before adding.   Proper performance requires that the product be kept in suspension.  Use a broom or brush to stir up the spa floor and recirculate the water, for 30 minutes, every 3-5 hours or as convenient.   Look for and remove any wet insulation.

Continue, in this manner, until the leak appears to have stopped.  Once the leaking has stopped, allow 2-4 days for proper drying out and curing to take place. 

Resume filtration and thoroughly stir the spa floor, so that the excess product may be filtered count.  Hose clean the filter cartridge several times, over the next few days.  Do not allow the filter cartridge to completely dry out, before a thorough rinse cleaning.  If the spa water is more that 3 months old, drain the spa and thoroughly clean the inside, to remove all vestiges of the Fix A Leak product.

If the spa has foam insulation, open the cabinet and use a fan to help dry the underside.  Remove any wet insulation. Allow 2-4 days, for the curing process to proceed properly.

Treatment may be repeated, if required.

Is It A Leak Or Evaporation? The Bucket Test.

Not all pool water loss from is due to a leak.  Evaporation is a major factor.  Depending on the water temperature, air temperature, relative humidity pool surface area and wind speed, evaporation can reach 1/4" (6 mm) to 1/2" (12 mm) per day.  In the absence of rain, that could amount to 2-4 inches per week, depending on conditions, at a particular location.  So some of what you surmise, as being due to a leak, could simply be due to evaporation.  When you see losses of more than 1/2" (12 mm) or you see direct evidence, such as puddling, a leak becomes much more likely.  Expect higher evaporation losses in the Arizona summer, as compared to a summer in Maine.  Covered spas do not tend to lose a lot of water, due to evaporation.  Depending what type of spa you have, direct evidence, such as puddling or wet insulation is the obvious and confirming sign of a leak.

In order to determine if a pool's excessive water loss is due to a leak, you can do the bucket test.  It is simple and cancels out the effects of evaporation.

The Bucket Test is a way to get a better estimate of true pool water loss, due to a leak. Place a plastic bucket, with water on the first or second step of the pool. Adjust the water level, in the bucket. to closely match that of the pool. Mark the height of the water level, in the bucket and in the pool. Over the next few days, monitor the water loss in the pool and in the bucket. The loss in the bucket is due solely to evaporation. If the pool lost more, that extra amount is due to a pool leak.

If it is determined there is a leak, you have several options. Look for an obvious sign of water loss accumulations. If none are found, most likely the leak is underground or beneath the pool floor, in the case of above ground pools. Consider using Fix A Leak. It has been sealing leaks successfully for over 30 years. Feed back letters attest to its effectiveness. If it is used and fails, then your choices become more apparent. It may not work 100% of the time, but it is the right place to start.
