- Our technicians will dive the pool and use a special dye to test any cracks and all pool shell penetrations such as lights, return fittings, and main drains.
- Using specialized equipment, our technicians will isolate and pressurize the plumbing lines to determine if the lines will hold pressure. If the lines fail a pressure test, then the line has a break somewhere between the pool and the equipment.
- As the water and air leak from the pipes while the plumbing is under pressure, our technicians will listen for underground water leaks using specialized leak location tools. This can be a time consuming process as we have to find how the pool builder ran the plumbing lines, and not all builders follow common practices.
- If the leaks cannot be heard, due to depth of pipes, small size of leak, or many other reasons, we can inject a gas into the plumbing lines and by using specialized gas detecting devices, “smell” the gas where the leaking pipe is located.
- In some cases, we use micro cameras to search inside the pipe to visually find the location of the leak.
- If the leak is was found during dye testing, the repair may take several paths, from sealing a light conduit, to cutting and sealing or stapling cracks, to water stopping around penetrations. Some of these repairs also require draining the pool and patching plaster. In these cases, it is unlikely the patch will match the current pool surface.
- Once a leak has been located, accessing the plumbing to repair the leak is the final step. This means digging through grass/dirt, cutting out deck, or removing sections of the floor or wall of the pool. This too can be a time consuming process as we do not know what lies under the surface - how thick is the deck, is there rock under the dirt, etc.
- Once the repair has been implemented, a pressure test will be repeated to ensure no additional leaks exists. Often times, the worst leak is the first one found, once repaired, smaller leaks show up during the test.
RECOMMENDATION: Pools with autofill systems which maintain a constant water level can mask or hide water loss. We recommend these systems be turned off for one to two days every quarter to verify no leaks exists.
