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.

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.

5. Pinpoint Leaks in Vinyl Liner
Use the LeakTrac
2200 to pinpoint even the smallest liner leaks in minutes.
