Leak detection in Miami, FL
Turn off every fixture and watch the water meter's leak indicator. If it moves, water is leaking somewhere. A plumber uses pressure tests, acoustic listening and thermal imaging to find the leak so only a small section of wall or floor has to be opened.

Leak detection for Miami homes
Hidden leaks waste water and rot framing before anyone sees them. In dry climates a slow leak can evaporate as fast as it drips, so a stain may never appear. The first sign is often a water bill that jumps between seasons that should match.
For the full guide, including what you can safely do before a plumber arrives, see leak detection explained.

Leak detection in Miami: what's different
Almost every Miami home is on a slab, so supply lines run under the floor where leaks stay hidden. Rising water bills, warm spots on tile and the sound of running water are the usual signs.
A plumber confirms the leak at the meter, then uses acoustic listening and thermal imaging to pinpoint it, so only a small section of floor is opened or the line can be rerouted through walls or the attic.

Miami housing and plumbing
Older homes from the 1920s–1960s often have cast-iron drains that corrode from the inside, a well-known problem across South Florida.

Other Miami conditions that affect plumbing
- Corroding cast-iron drains: Cast-iron drain pipes under older South Florida slabs often crack and scale, and many owners replace or line them.
- Hurricanes and flooding: Storm surge and heavy rain can back up drains; check valves and clear lines matter before storm season.
- Slab leaks: Supply lines under slabs leak quietly; rising water bills and warm floors are common signs.
- Limestone and high water table: South Florida sits on porous limestone with groundwater close to the surface, which affects drainage, septic systems in unsewered areas, and how quickly heavy rain floods streets and backs up drains.
How leak detection works in Miami
- 1
Meter and isolation test
Fixtures are shut off one branch at a time to see which part of the system is losing water.
- 2
Pinpoint
Acoustic listening, thermal imaging and moisture meters narrow the leak to a small area.
- 3
Open and repair
Only the area over the leak is opened. Repairs are made and pressure tested.
- 4
Document
You get a written description of the cause for insurance or a future buyer.

How to find and test your main water shutoff
Look where the water line enters the house, usually through the basement or crawl space wall facing the street, next to the water meter. Test it once a year by closing it and confirming water stops at a faucet, so you know it works before a pipe bursts.
