3. Marlig Industries


Fix-A-Leak by Marlig for Swimming Pool Spa Hot Tub Leaks 32 oz,White

Marlig Industries #ad - During circulation of water. 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. You may return to normal filtration. In most cases suction lines only leak water when the filter pump is shut off.

Sand filters: Set filter valve to filter and resume normal operation. With pump running add fix-a-LEAK slowly through skimmer or in front of any other suction intake. After the leak has stopped and given the proper time to cure, 24-48 hrs. 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. Backwash out unused FIX A-Leak as required.

It must be stirred back into suspension, either manually using a pool broom or mechanically with an automated pool cleaner every 4-6 hrs. Fix-a-leak is very heavy and will sink to the lowest point rather quickly. After adding fix-a-leak adjust suction to main drain. Rinse out unused FIX-A-Leak from filter as required. Note* never let cartridges or DE elements be left to dry before they are cleaned. Set filter valve to normal vacuum position.
