Customer Success Story · Underground & Main Line Leak Detection · Apple Valley, CA

The Yates Family, a Spring Valley Lake Border, Apple Valley homeowner, had been living with a water meter that keeps registering usage with everything indoors shut off for weeks before calling us. Longer lot setbacks on Apple Valley's rural-residential parcels mean correspondingly longer main line runs between the meter and the house. The leak was marked in that same visit, and the repair crew only had to open a small section instead of the whole area.

Why Apple Valley homes need underground & main line leak detection

Longer lot setbacks on Apple Valley's rural-residential parcels mean correspondingly longer main line runs between the meter and the house.

Water service in Apple Valley is provided by Apple Valley Ranchos Water Company, and confirming whether an issue is on your private plumbing or the utility side of the meter is one of the first things we check.

What underground & main line leak detection involves

The main line running from the water meter to your house, along with any underground irrigation lines, can develop a leak long before it ever reaches the surface. Soil often absorbs the water for a while, which means the yard can look normal even as the leak grows. We use acoustic ground microphones and tracer-gas methods to trace buried lines and identify the leak's position without trenching the entire run.

Acoustic correlators listen for the specific sound signature of pressurized water escaping underground, while tracer gas can be introduced into the line and detected at the surface directly above a leak, letting us mark a precise dig site instead of trenching the entire line.

Signs you may need underground & main line leak detection

  • A soft, spongy, or unusually green patch of lawn along the line's path
  • Water pooling at the surface with no obvious source
  • A water meter that keeps registering usage with everything indoors shut off
  • Reduced water pressure at the house
  • Sound of running water near the meter box or yard with fixtures off
  • A sinkhole or settling ground above a buried line

Apple Valley customers on underground & main line leak detection

★★★★★

“The floor in our hallway had a warm spot for weeks. They found the slab leak in under an hour with the listening equipment and marked a tiny area instead of tearing up the whole hallway. Huge relief.”

MTMarcus T. · Los Angeles, CA

“Our water bill jumped for two months straight and we couldn't find why. Turned out it was a slow leak behind the water heater. Professional, on time, and explained everything on the spot.”
