Professional Leak Detection & Repair (faucets, pipes, toilets) Services
What is leak detection & repair and when do you need it?
Leak detection and repair means finding water going somewhere it should not — and the hard part is usually the finding, not the fixing. Avanté Plumbing traces leaks in faucets, supply pipes, toilets, and lines running under slabs or inside walls across Santa Rosa and the wider North Bay. The obvious ones drip where you can see them. The expensive ones announce themselves as a water bill that climbed for no reason, a warm patch on a floor, a musty smell, staining on a ceiling, or a water meter that keeps ticking with every tap in the house shut off. A toilet that refills by itself can quietly waste more water than any dripping faucet in the building. We locate the actual source before opening anything up, so the repair is targeted rather than exploratory. Karl D'Angelo, CSLB licence #841938 (C-36 Plumbing).

How do I know if I have a hidden water leak?
The meter is the cheapest test you can run. Turn off every fixture and appliance, then check whether the water meter is still moving — if it is, water is going somewhere. Other common signs are a bill that jumps with no change in use, a warm patch on a slab floor, musty smell in a cabinet or wall, staining on ceilings below a bathroom, and pressure that has quietly dropped.
How do plumbers find a leak without opening walls?
By narrowing it down before cutting. Meter testing confirms a leak exists, isolating sections establishes which line it is on, and acoustic listening equipment, pressure testing and thermal imaging locate it along the run. The point is to open one section of wall or slab in the right place rather than several in the wrong ones.
Is a running toilet actually worth fixing?
Yes, because it is usually cheap and it is continuous. A toilet that runs is passing water constantly through the flapper or fill valve into the drain, and it is one of the most common causes of an unexplained bill rise. Both parts are inexpensive and readily replaceable — this is generally one of the smallest repairs in plumbing relative to what it saves.
