A visible leak is a repair. A hidden one is a search, and the search is where the money goes if it's done by opening walls until something turns up.
The EPA puts average household leaks at nearly 10,000 gallons per home per year, and the hidden ones account for most of that, because nobody fixes what nobody can see.
Run this test before you call. Turn off every fixture and appliance that uses water, then look at your meter. If the dial is still moving, water is going somewhere. It's the single most useful thing you can tell us, and it costs nothing.
Signs of a leak you can't see
- A water bill that jumped without a change in how you live.
- Running water audible with everything turned off.
- A warm patch on the floor, which points at a hot supply line beneath the slab.
- Pressure down across the whole property.
- Damp, blistering paint, or a musty smell confined to one area.
- Cracks appearing in floors or walls, in longer running cases.
- Grass greener in one patch of the yard, which can be a service line rather than a sewer problem.
How we find it
- Isolate. Work out whether it's on the supply side, the drainage side, or an irrigation line, because those are different searches.
- Pressure test the suspect system to confirm the loss is real and bound it.
- Acoustic location. Pressurised water escaping makes a characteristic noise that specialist equipment can track through concrete.
- Thermal imaging, which is particularly effective on hot water lines under slab because the leak warms the floor above it.
- Camera where the issue is on the drainage side rather than supply.
- Mark the spot and talk through the repair options before anything gets opened.
Why this is worth paying for
The alternative is exploratory demolition. On a slab home, that means breaking concrete in the most likely place, then the next most likely place. Detection converts a destructive search into a targeted one, and it frequently reveals that the smarter repair is to abandon the failed run and reroute entirely, which means no concrete comes up at all.
Slab construction in Tampa
Most homes here sit on a concrete slab rather than over a crawlspace, and that single fact drives almost everything about leak work locally. A supply line failure under a slab has nowhere to drip. Water tracks sideways through the fill, sometimes for weeks, before it surfaces as a damp patch, a warm spot or a bill that doesn't make sense. By the time it's visible it has usually been running long enough to matter.
The high water table complicates it further, since saturated ground masks some of the signs that would be obvious elsewhere. And in homes built between roughly 1978 and 1995, polybutylene supply pipe adds a particular pattern: failures at the fittings, often in multiple places over a short period. If we find one poly-B failure, the conversation usually widens to the system as a whole, because the second and third are generally not far behind.
