Most Yorba Linda homes are served by Yorba Linda Water District, and some get water from Golden State Water Company, depending on location. A leak in the private line from the meter to the house is usually the owner's repair, which a plumber can locate and fix. Call the number on this page to be connected with a local plumber in Yorba Linda.

Which water supplier serves my Yorba Linda address?
The City of Yorba Linda says most residents are on Yorba Linda Water District and some are on Golden State Water Company, with the provider depending on where the home sits. Your bill settles it. YLWD customer service is (714) 701-3000; Golden State Water lists a 24-hour customer service line, 1.800.999.4033. Call your supplier when water is surfacing at the meter or in the street, since that portion belongs to them.
What does a service line repair look like on a Yorba Linda lot?
The median Yorba Linda home dates to 1984, so most service lines are copper or plastic with decades of use behind them. Failures tend to show up at a fitting, at the riser where the pipe comes up beside the house, or where later landscaping cut into the line. The eastern side of the city has hillside areas and horse trails, and a sloped lot often means a longer run, retaining walls and water that travels downhill before it surfaces. A plumber traces the line, exposes the leak and decides with you whether a section repair is enough or a new line makes more sense.
Does the job need a permit, and is there anything extra?
Plan on a permit for a replacement. The City of Yorba Linda Building Division issues plumbing permits from City Hall at 4845 Casa Loma Avenue, 714-961-7120, with application forms submitted at the counter. The City's building FAQ also notes that Yorba Linda Water District may have its own plan submittal requirements that affect projects, so your plumber may need to check with the district on work near its connection.
A note on Yorba Linda water
YLWD water is about 85% local Orange County Basin groundwater and about 15% imported water from the Metropolitan Water District. Golden State Water's Placentia-Yorba Linda system reports an average hardness of 11.0 grains per gallon, ranging from 3.92 to 17.5, so mineral crust on old valves and fittings is common on that system. Before you need it, make sure the house shutoff turns freely; a crusted valve that won't close makes any leak harder to handle.
