Why Visalia homes need underground & main line leak detection

Visalia's newer tract neighborhoods have longer, more recently laid main lines than the shorter runs found in the historic downtown core.

Water service in Visalia is provided by California Water Service, 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

Visalia 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.”

PRPriya R. · Los Angeles, CA
★★★★★

“Salt air had corroded a fitting outside near the meter box. They traced it with the acoustic equipment without digging up my whole side yard first. Appreciated the straightforward report.”

DKDaniel K. · San Diego, CA
★★★★☆

“Good experience overall, technician was knowledgeable and thorough. Took a little longer than expected but they were clearly being careful about pinpointing the exact spot before marking it.”

AMAngela M. · San Diego, CA
★★★★★

“Old Victorian with plaster walls everywhere, so I was dreading this. They used thermal imaging and found the leak behind one wall panel instead of opening up the whole room. Saved us a big repair bill.”
