Finding the leak
Signs a leak is hiding somewhere
Hidden leaks tend to announce themselves indirectly. A water bill that climbs with no change in habits, the sound of running water when every tap is off, damp drywall, a musty smell, or a patch of floor that feels warm underfoot can all point to a pipe leaking out of sight. A warm spot can mean a hot water line under the slab.
A simple first test happens at the water meter. Turn off every fixture and appliance that uses water, then watch the meter’s leak indicator or dial for a few minutes. If it still moves, water is going somewhere on the property, and the job becomes narrowing down where.
Leak detection covers slab leaks under the foundation as well as lines in walls, ceilings and the yard. Once the leak is located, you hear what failed in plain terms and see a written price for the repair, whether that means opening a small section to fix the line or running a new length of pipe around the problem.

Riverside notes
Your side of the meter
Riverside Public Utilities serves most of the city, and Western Municipal Water District serves part of southeast Riverside. Generally, the utility is responsible up to and including the meter. A leak between the meter and the house, or anywhere inside, sits on the property owner’s side, and that is the stretch leak detection is built for.
If water is pooling at the meter box itself, call your utility before anything else. If the box is dry but the meter keeps turning with everything off, the leak is downstream of it, and that is a plumbing call. Your bill shows which utility you are with.
Riverside is the county seat of Riverside County and takes its name from the Santa Ana River, with Mount Rubidoux beside the river near downtown. The 91, the 60 and the I-215 all run through the city, and the trucks that come here are stocked the same way as everywhere else.
Leak questions from Riverside
- What is a slab leak?
- A slab leak is a break in a water line that runs under a home’s concrete foundation. Because the pipe is out of sight, the first signs are usually indirect: a rising water bill, the sound of running water, damp flooring or a warm spot on the floor. Leak detection pinpoints the spot so the repair disturbs as little of the floor as possible.
- Do I call Riverside Public Utilities or a plumber about a leak?
- Call Riverside Public Utilities, or Western Municipal Water District if it serves your address, when the leak is at the meter or on the street side of it. Generally, anything from the meter into the house belongs to the property owner and is plumbing work. If you cannot tell which side the leak is on, the meter test (everything off, then watch the dial) is a good place to start.
- Can a leak be found without tearing up walls and floors?
- Leak detection aims to find the leak first and open only where the repair needs to happen. Narrowing it down before cutting means a smaller opening in the wall, floor or yard. Some access is still needed to fix the pipe itself, and you see the plan and the written price before anything is opened.
- Is all of Riverside in your service area?
- Yes, Riverside is one of the 21 places on our service list. Crews are dispatched from the Rancho Cucamonga shop and reach the city on the 91, the 60 or the I-215. Give your address when you call so the office can schedule the visit.
- Is there a discount for veterans or seniors?
- Yes, veterans and seniors get 10% off a single qualifying job. Mention it when you book so it is applied to the written quote. The offer is printed on the trucks as well.
