Main Water Line Leak Detection in Pomona
The service line between your meter and house can leak underground for months, especially in older galvanized or copper lines. Wet spots in the yard, oddly green grass or a sinking area near the front of the house are clues. We use line tracers to map the pipe and ground microphones to hear the leak. That keeps excavation to a small, focused hole.
Sewer Line Leak Detection in Pomona, CA
Sewer line leaks can cause foul odors, slow drains and potential health hazards. Our team uses camera inspections to visually identify breaks, cracks or blockages within your sewer lines.

Frequently Asked Questions About Leak Detection in Pomona
The cost of leak detection in Pomona, CA can range from $250 to $800, depending on the complexity and location of the leak. Factors like slab leaks or hard-to-reach pipe leaks may be at the higher end. We provide a written estimate after our initial assessment.
Common signs include a sudden spike in your water bill, damp spots on walls or floors, mildew odors, visible mold growth, the sound of running water when no fixtures are in use, or a continuously running water meter even when all water is off.
Most residential leak detection appointments take one to three hours. Larger homes, commercial buildings or multiple leaks can take longer. We give you an time estimate when we schedule.
Leak detection itself usually does not require a permit. However, if the leak requires significant repairs, such as replacing a section of a main water line, gas line or extensive slab repair, then a plumbing permit from Pomona may be necessary. We will advise you on any permit requirements.
You can check your meter, test toilets with food coloring in the tank and look for damp spots. Finding leaks under slabs or inside walls requires professional equipment. That is where professional detection saves time and money.
We use acoustic ground microphones, thermal imaging cameras from brands like FLIR, line tracers, moisture meters and pressure test gauges. Each tool helps confirm a different type of leak. Using several together gives accurate results.
Many homeowners policies cover the cost of finding and accessing a sudden leak, though coverage varies. We provide a written report with photos to support your claim. Check with your insurer about your specific policy.
Small repairs usually do not, but reroutes, repipes and main line replacements often do. Requirements vary by city and county. We take care of any permits needed.
