What leak detection involves
Leak detection uses the water meter, pressure tests on isolated lines, acoustic listening equipment that picks up the sound of water escaping a pipe, thermal imaging and moisture meters.
The process narrows the search step by step: is there a leak at all, is it on the hot or cold side, inside or outside the house, in a wall, a ceiling or under the slab.
Once the location is marked, the plumber can repair it or recommend rerouting the line.
Signs you need leak detection
- Water bill higher than usual
- Meter moving with all fixtures off
- Running water sound
- Damp drywall, baseboards or carpet
- Mold or musty smells
- Cracks in tile or warm floor spots

Leak detection in Paramount: local context
Burst pipes in Southern California are rarely about cold. In Paramount, which incorporated in 1957 from the former communities of Hynes and Clearwater, many homes were built in the 1940s through 1960s. Their original galvanized steel or early copper lines are now well past their expected life.
The usual causes here are age and corrosion, high or surging water pressure, worn fittings and flexible supply hoses, and pipes under or inside concrete slabs that move as the ground shifts. Hard water in the region adds mineral build-up that wears pipes from the inside.

Have this ready when you call
- Your street address and ZIP code in Paramount
- What you are seeing, hearing or smelling, and when it started
- Which of these signs apply: water bill higher than usual; meter moving with all fixtures off
- Anything you have already shut off, reset or tried
- Photos of the problem area, taken before anything is moved or removed
- Whether anyone in the home is at risk, and the best times for a visit
A clear description helps the plumbing provider bring the right parts and equipment on the first visit.

Leak Detection: common questions
How accurate is acoustic leak detection?
In experienced hands it can often pinpoint a slab or underground leak to within a small area, but results depend on pipe material, depth and background noise.
