Leak Seal is specially formulated to fix minor leaks in pool, spa and hot tub plumbing lines and fittings without draining. It is convenient and easy-to-use. Application may be repeated if necessary.
Remove filter cartridge, grids from a D.E. Filter, or move filter control to re-circulate position for sand filters. Add 1/3 of this bottle for spas or entire bottle for pools as close to the skimmer or main drain. Turn on only the circulation system. DO NOT turn on heater or air blower. Run recirculation system for 5 hours for spas and 10 hours for pools. Refill spa or pool to proper level and let stand long enough to determine if leak is sealed. If leak is sealed, drain the spa and refill. For pools, normal operation can be resumed. If leak is not sealed, repeat the procedure again. See product label for specific application instructions. This product is not designed to seal leaks in swimming pool vinyl liners. Leak Seal is compatible with all hot tub sanitizers.
