Most faucet calls in San Bernardino come down to scale-coated cartridges, worn washers in older two-handle fixtures, or a supply connection that has started to weep under the sink. The city's tap water is hard groundwater, so mineral wear shows up sooner than many owners expect. Call the number on this page to be connected with a local plumber in San Bernardino.

Is it time to have the faucet looked at?
- The spout keeps dripping a minute or more after you close the handle
- A chalky ring has formed where the spout meets the sink deck
- The handle turns farther than it used to before the water stops
- Hot and cold no longer blend smoothly on a single-lever faucet
- The cabinet floor below the sink feels soft or smells musty
San Bernardino water, homes and faucets
San Bernardino Municipal Water Department (SBMWD) pumps all of its drinking water from the Bunker Hill groundwater basin, and its 2025 Consumer Confidence Report lists hardness averaging 242.2 mg/L, ranging from 130 to 330 mg/L. Water that hard leaves calcium on everything it touches. Inside a faucet, the deposits roughen the ceramic discs and rubber seals in the cartridge, so a valve that once closed with a light touch begins to leak or stick. The aerator screen at the tip of the spout collects the same grit, which is why a weak stream is often a cleaning job rather than a failed fixture.
Housing age matters as much as the water. In ZIP 92404, roughly 72 percent of houses were built in 1979 or earlier, and many kitchens and baths on the West Side and around Downtown still have compression faucets with rubber washers and multi-turn stop valves that rarely get exercised. Those stops can seize, so a plumber often checks them before taking the faucet apart.
SBMWD maintains the pipe from its main up to the meter. Everything from the meter to the house, and every fixture inside, belongs to the owner.
What moves the price
- Repair or new fixture: a cartridge, washer or O-ring kit takes less time than pulling and mounting a whole new faucet.
- Scale: mounting nuts and cartridges fused by minerals take longer to free, and sometimes have to be cut.
- Parts availability: common brands are easy to source; an older or discontinued model may not be worth rebuilding.
- Stops and supply lines: a frozen angle stop or a brittle supply hose is usually replaced while the water is off.
- Timing: after-hours and weekend calls usually cost more.
When you call
The number on this page connects you with an independent plumber who works in San Bernardino. Mention the faucet brand if you know it, whether it has one handle or two, and whether the leak is at the spout, the handle or under the sink. If water is coming up at the meter or the street rather than inside the house, SBMWD lists 909-384-5141 for water emergencies. Larger plumbing changes go through the City of San Bernardino Building & Safety Division, and the plumber can tell you whether yours needs a permit.
