Turn off every faucet and appliance and watch the meter for ten minutes. If the leak indicator moves, water is escaping somewhere. Call us and we will narrow it to a room, then to the exact fitting, before cutting anything.
Signs you need leak detection
- A bill that climbed without a change in how you use water
- The meter leak indicator turning with everything off
- Warm spots on a slab floor or a hissing sound in a wall
- Musty smell or soft flooring near a bathroom
- A water heater or toilet that seems to run on its own
How we handle it
- Meter and isolation testWe read the meter, then close branch valves one at a time to learn whether the leak is inside, outside or on the hot side.
- Pinpoint with toolsAcoustic listening, thermal imaging on hot lines and moisture meters take the guess out of where the water is going.
- Show you the sourceYou see the reading or the image before we open anything, along with the size of the access we need.
- Repair or quoteSmall leaks are fixed the same visit. Larger jobs, like a slab leak or a buried water line, get a written price first.

What you can do before we arrive
You can run the meter test yourself, and you can put a few drops of food coloring in each toilet tank. If color shows up in the bowl after twenty minutes without flushing, that toilet is leaking past its flapper and is likely your culprit.
What we see in Upstate homes
Greenville Water and the other Upstate providers bill on metered use, so a slow leak shows up on paper long before it shows up on the ceiling. Around older neighborhoods like Augusta Road and North Main, we often trace those leaks to galvanized branch lines or to toilet fill valves that never fully shut. In newer subdivisions out toward Simpsonville and Greer, the usual culprit is a crimp fitting under a slab or a nail through a PEX line.
Keeping it from coming back
Check the meter every few months with the house quiet, replace toilet flappers every few years, and keep an eye on the ceiling below bathrooms. Catching a leak at the dripping stage costs a fraction of finding it after the drywall is wet.
Questions about leak detection
Will you have to tear open my walls?
Only where the leak actually is. Pinpointing first keeps the opening small, often a single section of drywall or one tile.
Can you find a leak in the yard between the meter and the house?
Yes. Underground water service lines are traced with listening gear, and we mark the spot before any digging.
Is leak detection worth it for a small bill increase?
A toilet that runs all day can waste thousands of gallons a month. Finding it early usually costs less than the water it would waste in a season.
