Deep Fire Line Leak Detection

Noninvasive fire line leak detection for commercial, industrial, and residential properties. 

As seen on ABC7 News.

A leaking underground fire line doesn’t have to mean digging up your property or replacing the whole line. We pinpoint where the leak actually is, so your repair targets the real problem, and you avoid exploratory digging.


Signs You May Have a Fire Line Leak

  • A fire line pressure drop that you can’t explain
  • Wet or soft ground, or water pooling near the fire line, with no clear cause
  • A water bill that rises with no change in how much water you use
  • Sinkholes or settling in paving or landscaping above the line
  • A fire line that fails a pressure test


How We Find Fire Line Leaks
We use noninvasive equipment, including acoustic listening, pressure testing, and tracer methods, to locate leaks without exploratory digging. Our goal is to pinpoint the exact spot, so any repair is focused on the leak itself and not on a larger section of the line.


Who This Is For

  • Commercial buildings and business parks
  • Industrial sites and warehouses
  • Apartment communities and HOAs
  • Campuses, hotels and other properties with underground fire lines

Frequently Asked Questions

Underground fire line leak detection in Bay Area, CA

Q: Do you repair the leak too?

A: Yes. We find the leak first, using noninvasive methods, and we can repair it too. Call us at (510) 960-0399 to talk about what your property needs.

Q: Do I have to dig up the line to find the leak?

A: No. We find the leak first using noninvasive methods, so digging and repairs, if needed, happen only where the leak is.

Q: Can you find a leak in a deep underground line?

A: Yes. Locating leaks in deep underground fire lines is one of the things we do.

Q: How do I know I have a fire line leak?

A: Common signs are unexplained pressure loss, wet ground near the line and a higher water bill. A leak detection inspection can confirm it.

Q: What types of properties do you serve?

A: Commercial, industrial and multi-family properties, as well as homes with underground fire lines.
