A hidden leak is an emergency when water is already moving
Emergency leak detection in Dixon, CA is for the moment you find water you cannot explain. Look for a growing ceiling stain, a warm or damp wall, a meter dial that keeps turning or a floor that feels soft. Our line is answered 24/7, and a plumber can be scheduled the same day when availability allows.
While you wait, shut off the main water valve if the leak is active. Turn off power to any room where water has reached outlets, and move belongings away from the wet area. If you cannot find the valve, say so on the call.
Meter still running with everything off: how to read it
This is the most common way people learn they have a leak. A few minutes at the meter tells you whether the problem is inside your property or somewhere else.
Turn everything off
Close every tap, stop the dishwasher and washer, and make sure the ice maker is not filling.
Find the meter
It is usually in a box near the street, and the box lid lifts with a screwdriver.
Look at the low-flow indicator
Many meters have a small triangle or dial that spins when any water moves, even a trickle.
Check again after an hour
If the dial or the numbers moved with all water off, water is leaking somewhere past the meter.
A meter that moves with everything off means a leak on your side of the meter. Then shut the main valve at the house and see whether the meter stops, which tells you if the leak is outside the house or inside it.
Symptoms by location: where leaks hide
Water finds its own path, so the damp spot is rarely above the leak. These are the patterns plumbers see most often.
Ceiling or wall stain
A pipe in the wall or attic is leaking, and the stain is where water finally shows.
Warm spot on the floor
A hot water line under a slab or floor is leaking.
Musty smell or soft flooring
A slow leak in a crawlspace, under a sink or behind a wall.
High bill with no change in habits
A running toilet, an irrigation leak or a line leak is using water.
Sound of water when nothing is on
A pressurized line is leaking inside a wall or under the house.
How leaks are found and what each method suits
A plumber works from the least invasive method up. This table shows the usual order.
| Method | What it finds | Good for |
|---|---|---|
| Meter and shutoff test | Whether the leak is on your side of the meter, and which side of the house valve | First step on every high bill or running meter. |
| Pressure test | Whether a water line loses pressure when isolated | Confirming a supply line leak. |
| Electronic listening | The sound of water escaping a pressurized pipe | Slab, wall and buried line leaks. |
| Thermal imaging | Temperature differences from hot water leaks or damp materials | Hot lines under floors and wet drywall. |
| Camera inspection | Drain line leaks, cracks and offset joints | Sewer or drain lines suspected of leaking. |
When the leak is under a concrete floor, the next step is covered on our slab leak repair page, and a leaking supply line outside the house continues on water line repair.
Water you cannot explain?
Call the 24/7 line and describe where you see it. A same-day appointment is offered when available.
Crawlspaces, irrigation and yard leaks
A crawlspace leak smells musty and may leave wet soil, white mineral stains on pipes or a sagging insulation batt. It gets worse slowly and is easy to miss until floors soften, so a flashlight check after a few days of high bills is worthwhile.
Irrigation lines are a common leak source in a dry-summer region such as the Sacramento Valley. A wet patch of lawn, a valve box full of water or a sprinkler that never stops can all hide a pressurized leak, and a plumber can test the line separately from the house supply.
A leak in the yard or under a driveway between the meter and the house is a buried line leak. Those are found with listening equipment and a pressure test, and repaired as described on the water line page.
Dixon's water, your bill and what the city can tell you
Source type: City of Dixon water quality report and City of Dixon utility pages.The City of Dixon supplies water from groundwater wells, and its 2024 report lists system pressure between 52 and 62 pounds per square inch. Constant pressure means a small leak runs all day and night, which is why a pinhole in a line can add a noticeable amount to a monthly bill.
Your utility bill and meter history are the best evidence of a leak. Ask the City of Dixon utility billing office for your recent usage, and compare it with a normal month. A jump with no change in household habits is a reason to run the meter test above.
The city's water operations office handles problems on its side of the meter. If you are not sure where the city's responsibility ends and yours begins at your address, ask them before you pay for repairs.
Pipe rules shape where a leak can hide. The City of Dixon's handout cites section 604.1 of the California Plumbing Code, which is based on the Uniform Plumbing Code (UPC), which does not allow PVC or polyethylene for water supply in the situations it covers.
What changes the price of leak detection
Detection is priced by the work involved, and the plumber tells you the price before starting.
Homeowners insurance often covers sudden, accidental water damage, but may exclude a slow leak that went on for months. Some policies also pay for the cost of tearing out and replacing materials to reach the leak. Ask your agent before work starts and document everything.
For your real number, call (916) 312-0578 and describe the symptom, such as the meter, the stain or the bill.
