Why Costa Mesa Needs Professional Leak Detection

Most Costa Mesa addresses receive water from Mesa Water District; some receive it from Irvine Ranch Water District (IRWD). Check the supplier on your water bill. Mesa Water's residential meter guide says the meter is usually between the sidewalk and curb under a cement cover. Turn off all water use in the home, then watch the low-flow indicator on the meter dial. Movement indicates a possible leak between the meter and your plumbing system. Check toilets, faucets, irrigation and outdoor hose bibs first. If nothing obvious explains continued movement, KCB can isolate and pressure-test lines to narrow whether the source is a service line, irrigation, a slab or a wall. Ask your water supplier about anything at the meter itself; IRWD customers should check with IRWD.

If testing confirms a leak under the slab, our slab leak repair guide compares spot repair, reroute, and repipe options.

Why KCB Plumbing

Leak Detection Benefits in Costa Mesa

A Useful Meter Check

Mesa Water's low-flow indicator check gives you a starting point. Continued movement deserves investigation, but does not by itself identify a slab leak.

Line Isolation Before Floor Access

KCB isolates lines and pressure-tests to narrow the affected supply line before planning an opening. We explain what the testing supports and where further confirmation is needed.

Costa Mesa-Based Service

Our office is on Harbor Blvd. Call Monday–Friday, 7 AM–6 PM, and Saturday–Sunday, 8 AM–5 PM to share the meter result, floor symptoms and any previous repairs, and check appointment availability.

Repair Choices With an Upfront Quote

Once the source is narrowed, we compare a spot repair, reroute or repipe according to pipe condition and access. Review the proposed work and quote before approving a repair.

Our Process

How Leak Detection Works

1

Check the Meter and Common Sources

Following Mesa Water's guide, turn off water use in the home and check the low-flow indicator for movement. Check toilets, faucets, irrigation and outdoor hose bibs for a source that explains it. Contact your supplier about the meter itself.

2

Isolate and Pressure-Test

If the meter keeps moving and no obvious source explains it, KCB isolates lines and pressure-tests to narrow a service-line, irrigation, slab or wall leak before opening a floor. Testing narrows the search; further confirmation may be needed.

3

Compare and Quote the Repair

Review spot repair, reroute or repipe options based on the findings, pipe condition and access. KCB provides an upfront quote; confirm any opening and restoration in the scope before approving work.

Common Questions

Leak Detection in Costa Mesa FAQ

How do I check my Costa Mesa water meter for a leak?

Mesa Water says the meter is usually between the sidewalk and curb under a cement cover. Turn off all water use in the home and check the dial's low-flow indicator. Movement indicates a possible leak between the meter and your plumbing system. Check common sources such as toilets, faucets, irrigation and outdoor hose bibs. Ask your supplier about anything at the meter itself.

The meter is moving but I can't find a leak. What next?

If toilets, faucets, irrigation and outdoor hose bibs do not explain continued movement, call KCB at (714) 894-6520 Monday–Friday, 7 AM–6 PM, and Saturday–Sunday, 8 AM–5 PM. We can isolate lines and pressure-test to narrow the source before discussing access and repair. A moving meter alone does not tell you whether the leak is beneath the slab.

How do you investigate a possible slab leak before opening the floor?

KCB uses line isolation and pressure testing to narrow the affected line before planning floor access. Tell us about warm floor spots, running-water sounds with fixtures off and continued meter movement. Those clues justify testing, but do not establish the exact location. An opening may still be needed for confirmation and repair.

Which water district serves my Costa Mesa address?

Most Costa Mesa addresses receive water from Mesa Water District; some receive it from Irvine Ranch Water District. Your water bill names your supplier. IRWD customers should check with IRWD about meter concerns.

Does finding a slab leak mean I need to repipe?

The findings, surrounding pipe condition, access and repair history guide the choice. A spot repair, reroute or repipe may be appropriate. KCB explains the options and provides an upfront quote before you approve work.

“The owner Kevin Blue has done plumbing work for me before. He is very helpful and knowledgeable. He always arrives as promised and the work is always satisfactorily completed.”
LYNDA E.Angi · May 2005Read on Angi
“Keevin was extremely personable, patient (big plus!), and knowledgeable. He explained the issues that we had in our new home and answered all of our questions, and most importantly, understood that we were on a budget considering there were so many things that we needed to take care of. My husband is probably one of the most suspicious persons on earth but even he found Keevin to be very trustworthy and straightforward with his suggestions and advice.”
