Pool leak pressure testing

Pressure testing is how a locator proves a buried line is open when the shell looks fine. They cap zones, add air or water pressure, and watch the gauge. Request that visit if you already know the plaster is not the problem — or if you do not know. This page does not run a test from a form.

When pressure testing is the right next step

Dye on the steps and lights showed nothing. The pool still drops with the pump off or on. The deck has a void, a wet planter, or a hollow sound. Those are the usual reasons someone asks for a pressure test.

It is also the usual method after a remodel cut through a line. If you just added a waterfall or replaced coping, say so. The test plan changes.

What happens on site

The locator isolates suction from returns, and sometimes spa lines from the main pool. A holding gauge is a pass. A falling gauge is a fail on that zone. Finding the exact break may still need listening gear or a small deck opening.

Pressure testing is not the same as a city plumbing inspection. It is a diagnostic. We do not issue a certificate.

Typical cost — not a bid

In this market the pressure-test work is often part of a locate package in the low-to-mid hundreds. Extra zones (spa, cleaner line, water feature) can add time. Opening concrete to expose a failed section is not included in a test fee unless someone wrote that in a quote you do not have yet.

This website will not invent that quote.

What to send

Number of skimmers, whether there is a spa or cleaner line, and whether anyone has already capped the returns. If a prior company pressure-tested and left marks on the unions, say that so the next visit does not start from zero unless you want it to.
