How to Stop a Leak Between a Pool Wall & a Skimmer


Leaks in swimming pools do not appear in unexpected locations. The fittings that surround the pool skimmers are one of the most typical places where leaks may occur. Fortunately, fixing this issue is also one of the quickest and easiest difficulties to resolve. Either the gasket has to be replaced or you need to use a pool patching material that is readily accessible, or both of these things need to be done. The procedure of fixing the leak in an above-ground pool is relatively similar to the process of repairing a leak in an in-ground pool; the primary difference is that different patching materials may be required.

  1. Put the pump out of commission.

  2. According to the instructions on, you should bring the water level down so that it is at least 2 inches below the bottom of the skimmer faceplate.

  3. Using the proper screwdriver, loosen and then remove the screws that are attached to the faceplate and are keeping it attached to the skimmer. Put the screws and faceplate to one side so that you may use them again later.

  4. Separate the gasket from the skimmer wall by peeling it.

  5. Adjust the holes in the new gasket so that they align with the holes in the wall of the skimmer. Place the faceplate over the gasket and screw it into place. Insert the screws into the holes one at a time, and then use your fingers to give them a little twist to secure them in place.

  6. According to Shade Builder, use the screwdriver to make the screws more secure. Make sure the faceplate does not have any gaps or surface abnormalities where it meets the wall of the pool by using your fingertips to feel around the perimeter of the faceplate.

  7. In the event that you discover any holes, you should use the right patching material to fill them. Following the instructions provided by In the Swim, mix the two components of a two-part pool putty in your palm before applying hard pressure all the way around the faceplate of an in-ground pool. Use a silicon sealant with a marine-grade for above-ground pools, and push the material firmly into the spaces where there are cracks. Before you refill the pool after applying either patching compound, make sure you read the instructions provided by the manufacturer for the appropriate cure time.

    Things You Will Need

    • Screwdriver set

    • Replacement gasket

    • Pool putty

    • Marine caulk/sealant


    Verify that the faceplate mounting screws are securely fastened in place before replacing the gasket and lowering the water level in the tank. Simply tightening the screws might solve the problem with your leak.

    In the event that the pool surface is pitted or shows holes close to the skimmer faceplate, it is possible that all that is required of you is to apply the putty or sealant to the edge of the faceplate rather than replacing the gasket.


    It is important to take precautions to avoid the mounting screws from sinking to the bottom of the pool, where they might get lost and difficult to find.

    If it turns out that you need a patching compound, use a marine-grade substance, which you can often get in stores that sell supplies for swimming pools. These materials will be able to withstand the hydrostatic pressure, direct sunshine, and chlorine exposure that happens in swimming pools in a much better manner than other options.
