Pool pressure test
A pool pressure test is how a locator proves a buried suction or return line is open when the shell looks fine. They isolate zones, add air or water pressure, and watch the gauge. A holding gauge is a pass on that zone. A falling gauge is a fail. This page does not run the test.
What “pressure test” means on a pool
It is not a city plumbing inspection and not a certificate. It is a diagnostic on the pool’s underground piping. The locator caps returns, suction, and sometimes spa or cleaner lines so each zone can be judged on its own.
If you already know the plaster is not the problem — or you do not know — request pool leak pressure testing. You do not need to pick the method in the form.
When Valley locators reach for it
Dye on the steps and lights showed nothing. The pool still drops. A planter is wet, the deck sounds hollow, or a remodel just cut through a line. Those are the usual reasons a pressure test is the next step.
Raised spas, sheer descents, and cleaner lines are common on later Phoenix-area builds. Extra zones add time. Write whether a spa or water feature shares the system.
What happens on site — and what does not
A holding gauge means that zone held. A falling gauge means that zone is open. Finding the exact break may still need listening gear or a small deck opening. The test itself does not repair the line.
Some firms locate only. Some also open a deck later. Ask the person who calls which they offer. This website will not invent that split or a same-day repair.
Do not DIY this on a live system
Capping the wrong union or adding pressure to a line you have not isolated can damage equipment. If water is already at the timer or heater, shut the system down if you know how, then write that on the request.

Questions
Is a pool pressure test the same as a bucket test?
No. A bucket test compares weather to still-water drop. A pressure test isolates buried piping. They answer different questions.
Will the test tell me exactly where to open the deck?
It tells you which zone failed. Pinpointing the break can take more gear or a small opening. Ask the locator what they will do after a fail.
Do I get a certificate?
Not from this website, and not as a city inspection. A pressure test is a diagnostic for the pool piping. We do not issue paperwork.
Should I pressure-test the lines myself?
No. Isolation and pressure on the wrong zone can damage equipment. Request a locate and describe what you already see.
