Emergency leak detection when water is hidden
Leak detection in Coachella, CA is the process of finding where pressurized water or drain water is escaping, using meter tests, pressure tests and electronic equipment before anyone opens a wall, floor or yard. A hidden leak is an emergency when water is already stained a ceiling, is running under a slab or is spinning your meter with every fixture off. Our 24/7 line is open at night and on weekends.
Do one thing right now. Turn off every fixture, then watch the small leak indicator on your water meter. If it keeps moving, water is escaping somewhere. Close the main shutoff at the house and see whether the movement stops, because that tells a technician whether the leak is inside the home or in the line from the meter.
Symptoms we are asked about most
Callers rarely say leak detection. They describe what they see.
- The meter runs with every faucet closed
- The water bill rises without a change in use
- A warm spot on the floor or hot water that arrives slowly
- A damp or stained ceiling, wall or baseboard
- Low water pressure that came on gradually
- Sound of running water at night with nothing on
- Green or wet patches in the yard along the supply line
How the hidden leak is found
The process is a narrowing. A meter test splits the house from the service line. Pressure testing isolates hot and cold lines. Acoustic listening devices pick up the hiss of escaping water through floors and soil. Thermal imaging can show a warm slab section when a hot line leaks. Tracer gas is held back for the tough cases where the other tools disagree.
Once the leak is pinpointed, the repair is scoped to the exact spot. Compare that with cutting random holes in drywall. Locating first is almost always cheaper for the home, even when the detection itself is a separate line item.
Where leaks hide in desert homes
Under the slab
Most homes here sit on concrete slabs, so supply lines run in or under the foundation. See slab leak repair.
Behind walls and ceilings
Pinhole copper leaks and failed supply connections can run for weeks before a stain shows.
Service line from the meter
The pipe between the utility meter and the house is the owner's responsibility.
Irrigation and yard lines
Sprinkler laterals, valve boxes and pool or spa plumbing leak quietly and drive up the water bill.
The utility meter and who owns what in Coachella
In Coachella, the City's Utilities Department supplies water, and its water emergency standby line is (760) 578-7098 for a main break in the street. Plumbing on the property owner's side of the meter, including the pipe to the house, belongs to the owner, and California's plumbing contractor license class covers that work.
That boundary is practical. If water is bubbling up in the street or at the meter itself, call the City. If the meter is spinning and nothing is wet at the curb, the leak is probably in your service line or inside the house, and that is where leak detection starts.

Which test answers which question
| Test | What it shows |
|---|---|
| Meter check with fixtures off | Whether any water is leaving the system |
| Main shutoff test | Whether the leak is before or after the house valve |
| Hot and cold isolation | Which supply line is leaking |
| Acoustic listening | The spot where the line is hissing under floor or soil |
| Thermal imaging | Warm paths from hot line leaks |
What leak detection costs
The final number depends on how hard the leak is to find. Price is stated before work starts.
Insurance note: many policies cover resulting damage from a sudden leak but not the cost of finding or fixing a long-term slow leak. Ask your insurer whether detection is reimbursed.

Common questions
Yes. The 24/7 line is staffed, and a technician can be scheduled for the same day when openings allow. If water is entering the house, shut off the main first.
Turn off all water, then watch the meter. If it moves, you have a leak. Seasonal irrigation can also raise a desert water bill without any leak.
Only after the leak has been located. The goal is a small, targeted opening.
Water on the street side of the meter is the City's. Water on your side is yours. Call the City Utilities number for a main break.
Yes. Irrigation and pool plumbing are common sources of hidden leaks, and they use the same pressure-test approach.
Note the meter reading and time, close the main valve if water is entering the house, and move valuables from wet areas.
