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.

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.

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.

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.
