Pool Leak Repair in Gilbert, AZ

Testing to find where the water goes, then a repair at the source.

Pool Leak Repair Starts With Proof

Every pool in Gilbert loses water to evaporation, and in summer that loss is noticeable. The first job in pool leak repair is proving whether you have a leak at all.

A bucket test settles it. A bucket of pool water sits on a step for a day or two, and we compare its drop with the pool's. If the pool falls faster, something besides the sun is taking water.

From there we narrow it down. Dye tests show leaks at skimmers, fittings and light niches. Pressure tests on each plumbing line show whether the leak is underground.

Pool Leak Repair Questions

How do I know if my pool is leaking or just evaporating?

Run a bucket test, or let us run one. If the pool drops noticeably faster than the bucket over the same period, there's a leak.

Can a pool leak be fixed without draining?

Most can. Skimmer cracks, fitting leaks and light niches are usually sealed under water. Underground line repairs mean digging, not draining.

What if the leak is under the deck?

We pressure test to find the line, then open the smallest section of deck that reaches it. We tell you before any cutting starts.

Can a leak damage my yard or house?

A steady leak can soften soil near the pool and around the equipment. That's a good reason to test early rather than keep topping off.
