Swimming Pool Leak Detection

Leaking Pool Problems? Early detection of a swimming pool leak can easily save you large amounts of money. Due to evaporation, splashouts and backwash waste water your pool will naturally lose some water. If your adding more than 2" of water to your pool in one week, you most likely have a leak that you need to consider repairing. Even though swimming pools are intended to be watertight, sealants will deteriorate over time while other parts of your pool settle, shift, or wear out. Swimming pool leaks can come from any of the plumbing, fittings, accessories, or through the liner itself.

We highly recommend repairing your swimming pool leaks not only to save hydro, water and chemicals, but to additionally prevent undermining swimming pool structural components, and washing away fill sand.

Basic Leak Detection Process, Tips & Resources

  • Gather Information

    1. Gather Information

    Through conversations with the pool owner and observations of the pool, confirm that the leak symptom being observed is indeed the result of a leak. A "Bucket Test" can be performed to determine how much of the observed water loss is due to evaporation and how much is due to a leak. Other tests such as the "Pump On/Pump Off Test" will provide a useful base of information that will be helpful as you continue the leak detection process. Our Basic Leak Detection CD-rom provides a detailed overview of the entire leak detection process including these initial tests.

  • Pressure Test Plumbing Lines

    2. Pressure Test Plumbing Lines

    Regardless of the suspected location of the leak, a pressure test of all plumbing lines should be done to confirm whether they do or do not have a leak. Plug all but one of the openings in the pipe to be tested with assorted Closed Test Plugs. Set up a Pressure Induction System at the remaining opening (see also Pressure Testing Kits). Use water pressure from a garden hose to bring the plugged plumbing system up to 20 psi. Close the valve on the Pressure Tester and watch for the pressure to drop, which indicates a leak. If all plumbing lines hold pressure, go to step 4.

  • Pin Point Underground Plumbing Leaks

    3. Pin Point Underground Plumbing Leaks

    By using a regulated air source (compressor or nitrogen tank) to induce a constant stream of air into the leaking line a noise is created underground as air escapes into water saturated soil. Use a Listening Device to listen through the earth for sound. The leak will be at the point where the sound is loudest and clearest.


  • Check Fittings and Cracks in Pool Structures

    4. Check Fittings and Cracks in Pool Structures

    Using a Dye Tester, put a small amount of dye near suspected leak areas in the structure of the pool to see if the dye is pulled out of the pool. Check skimmers, return fittings, lights, cracks, main drains, and hydrostatic valves. Diving Equipment may be necessary for checking for leaks at the bottom of the pool.


  • Pinpoint Leaks in Vinyl Liner

    4. Pinpoint Leaks in Vinyl Liner

    Use the LeakTrac 2200 to pinpoint even the smallest liner leaks in minutes.
