Fix-A-Leak is a blended concentrated material designed to seal leaks in virtually any material. It can be applied for leaks in the shell and works equally well in plumbing. Fix-A-Leak will seal holes 1/8" in diameter and will form a permanent seal.Use 1 quart per pool up to 22,000 gallons. Do not use in excess of 1 quart per 5,000 gallons of water.Directions:Shake Well Before Using1. Bypass FILTER MEDIA before adding FIX-A-LEAK to water. Sand filters: set filter valve to recirculate. Other types: remove cartridges DE elements from filter tank. Then proceed to circulate through empty tank.2. With pump running, add FIX-A-LEAK slowly through skimmer or in front of any other suction intake.3. After adding FIX-A-LEAK adjust suction to main drain. If this is not possible, the vacuum cleaner could be used alternatively, simply by placing the vacuum in deepest part of pool and connect to normal vacuum connection. Set filter valve to normal vacuum position.4. FIX-A-LEAK is very heavy and will sink to the lowest point rather quickly. It must be stirred back into suspension, either manually using a pool broom or mechnically with a automated pool cleaner every 4-6 hrs. during circulation of water.5. Continue to recirculate water until the leak has stopped.6. Mark level of water in pool and check for 2-3 days to determine if the leak has stopped.7. After the leak has stopped and given the proper time to cure (24-48 hrs.) you may return to normal filtration. Sand Filters: Set filter 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 unsed FIX-A-LEAK from filter as required. *NOTE* Never let cartridges of DE elements be left to dry before they are cleaned.8. Treatment can be repeated if necessary.*NOTE* Suction Line LeaksSuction Leaks are usually known by air mixed with the water at the return fittings. In most cases suction lines only leak water when the filter pump is shut off. Normal Circulation will simply draw FIX-A-LEAK away from the leak and if the pump is shut off the material will simply not get to the leak. You must reverse the flow of water, to force the material through the leak under pressure. Preferably 5-10 psi. untill the leak has stopped. When this has been achieved, gradually increase pressure to 15-25 psi. to insure a proper seal.VERY IMPORTANT:After sealing a suction leak "it" is a must to leave suction off the repaired line for no less than 48 hrs. FIX-A-LEAK requires time to cure and harden.Miscellaneous Leaks:If you suspect a leak around fittings inside the pool (such as return fittings) lights, skimmer(s) or steps, etc. Shut down pump. Apply FIX-A-LEAK directly to the leak using a squeeze bottle, similar to a ketchup bottle. Allow a minimum of 48 hrs. to cure before starting up circulation.NOTE: FIX-A-LEAK has been thoroughly field-tested under various weather conditions, and has proven to be effective in sealing leaks. FIX-A-LEAK is also an excellent preventative maintenance aid, as it coats all surfaces that it comes in contact with, it cuts down on formation of rust and corrosion.
