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

How the work is done, step by step

  1. 1

    Meter and fixture check

    Fixtures are checked and the meter is watched.

  2. 2

    Isolate lines

    Hot, cold and outside lines are tested separately.

  3. 3

    Pinpoint

    Acoustic and thermal tools narrow the location.

  4. 4

    Mark and recommend

    You get the location and repair options.

What affects the cost

  • Whether the leak is inside, under the slab or outside
  • How many lines must be tested
  • Access to the location

Every job is quoted by the provider after an assessment. No price on this page is a quote.

What you can do yourself, and when to stop

Generally safe to do

  • Watch the water meter with all fixtures off
  • Check toilets with a few drops of food coloring in the tank
  • Look under sinks and around the water heater

Stop and call a pro

  • The meter moves and you cannot find the leak
  • Floors are warm or wet
  • You suspect a leak under the slab

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.

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.
