Pools lose water. That's a fact of owning one. Evaporation, splash-out, backwashing the filter — there are plenty of normal reasons the water level drops a bit week to week.
But there's a difference between normal loss and an actual leak. And figuring out which one you're dealing with is more involved than it sounds, because pool leaks almost never announce themselves. The water just keeps getting lower, the bills slowly go up, and by the time the problem becomes obvious, it's been going on for a while.
Leak detection is one of the more specialized services we provide at Precision Pool Inspection — and we approach it in two distinct ways, depending on what the situation calls for.
Before anything else, there's a simple way to check whether you're dealing with evaporation or a real leak. Fill a bucket with pool water and set it on a pool step, matching the water level inside the bucket to the pool water level outside it. After 24–48 hours, compare the two. If the pool has dropped more than the bucket, you probably have a leak.
This doesn't tell you where the leak is — that's where things get more involved. But it tells you something real is happening.
Our computer leak analysis is a water-loss measurement test. We use a calibrated monitoring system to measure the pool's water level over a set time period under controlled conditions, isolating variables to determine whether water is escaping through the shell or the plumbing.
The biggest advantage of this method is that it's non-invasive. No digging. No pressure-testing that requires shutting down equipment for extended periods. The pool stays operational throughout the test, which is critical when the inspection is happening as part of a real estate transaction and time is a factor.
It's also precise. The data tells us the rate of water loss, which gives us a clear answer: is there a leak, and if so, is it significant enough to require further investigation?
For buyers under contract, computer leak analysis can be added to a standard pool inspection to provide more comprehensive information without extending the inspection window in any meaningful way. For homeowners who've been noticing higher water bills or unexplained water loss, it's a cleaner starting point than guessing.
When a leak is confirmed or strongly suspected in a specific location — particularly in the pool shell itself, around fittings, or in the main drain — we bring in professional leak detection divers.
This is exactly what it sounds like: trained divers with specialized equipment going into the pool to inspect every inch of the shell below the waterline. Cracks in the plaster or fiberglass, damaged fittings around return jets, deteriorating gaskets around the main drain — these are the things that are impossible to assess from above the water's surface.
Leak detection diving is typically a next step after computer analysis confirms water loss, or when a visual inspection of the pool deck or wet walls around equipment suggests the problem is in or around the pool structure itself.
Leaks in the underground plumbing — the return lines and suction lines that run beneath your yard between the pool and the equipment pad — are the most expensive to fix and the most important to catch early. Water leaking into the soil around these lines can, over time, cause soil erosion, deck settling, and structural movement that extends well beyond the pool itself.
These leaks don't show up on visual inspections. They're typically identified through computer leak analysis (which shows loss even when the equipment is isolated) or through pressure testing of the plumbing lines, which we can help coordinate.
Call a specialist. Not a general home inspector, not a pool cleaning service, and not a repair contractor — because here's something worth knowing: Precision Pool Inspection does not perform repairs. We inspect and detect. That's it.
This matters because a company that both finds the leak and repairs it has a financial incentive to find (or create) problems. We have no such incentive. Our job is to give you accurate information, and then you can hire the contractor of your choice to do the repair work.
If you're buying a home in New Jersey and the pool inspection reveals water loss, or if you've been noticing your pool losing more water than expected, schedule a leak analysis. The earlier a leak is caught, the less it typically costs to fix.
