Pool Leak Detection: How It Works
Losing an inch of water a week? In the Coachella Valley, some of that is evaporation — but if it's more than a quarter inch a day, you have a leak. Here's how a professional finds it without tearing up your deck.
1. The bucket test
First we confirm a real leak vs. evaporation. A bucket of pool water sits on the top step; after 24 hours we compare the bucket's drop to the pool's. If the pool lost more, it's leaking.
2. Isolate: structure vs. plumbing
We shut off the pump and see if the water still drops. Stops dropping = plumbing leak. Keeps dropping = shell, tile line, or light housing leak.
3. Pressure test the lines
Suction and return lines get plugged and pressurized. A gauge drop tells us exactly which line has failed — skimmer, main drain, return, or cleaner line.
4. Electronic + dye confirmation
Acoustic listening equipment pinpoints the break under decking. Non-toxic dye at suspected shell cracks confirms surface leaks before any repair work begins.
What does pool leak detection cost?
Most Coachella Valley pool leak inspections run $350–$550, which includes pressure testing and pinpoint acoustic detection. The detection fee is credited toward any repair we perform.
Common repairs range from $450 for a skimmer reseal to $2,400+ for a broken main drain line under the decking. Related reading: 7 Warning Signs of a Slab Leak — the same acoustic tools find slab and pool leaks alike.
