Most Yorba Linda homes get water from the Yorba Linda Water District, but some addresses are on Golden State Water Company, and permits come from the City of Yorba Linda Building Division. Plumber Riverside CA is a free referral service, not a plumbing contractor. Call the number on this page to be connected with a local plumber in Yorba Linda.

Plumbing services in Yorba Linda
An Orange County city across the hills
Yorba Linda is in northeastern Orange County, about 24 miles from Riverside in a straight line, with SR 91, Imperial Highway (SR 90) and the SR 241 toll road nearby. It incorporated in 1967 and had 68,336 residents in 2020. The city calls itself the "Land of Gracious Living." It is home to the Richard Nixon Presidential Library and Museum and the Savi Ranch shopping district, with Chino Hills State Park along its northern edge and horse trails and hillside neighborhoods on the east side.
Two water providers, so check your bill
According to the city, most residents are served by the Yorba Linda Water District (YLWD), while Golden State Water Company serves some residents, and which one you have depends on where the house sits. YLWD draws roughly 85 percent of its supply from wells in the Orange County Groundwater Basin and buys about 15 percent from the Metropolitan Water District of Southern California. YLWD customer service is (714) 701-3000.
Golden State Water's Placentia-Yorba Linda system blends Orange County Basin groundwater with imported Colorado River and State Water Project water. Its water quality report says chlorine is added as a disinfectant and that the imported water it buys contains chloramine. It lists hardness averaging 11.0 grains per gallon, with a range of 3.92 to 17.5, which is plenty to leave scale in water heaters and on shower glass. Golden State Water's customer service line is 1.800.999.4033. YLWD also describes its role as providing sewer service; the sewer agency for Golden State Water addresses is not confirmed, so check your bill.
Housing age and typical work
The median Yorba Linda home was built in 1984. Many houses are now old enough for a second or third water heater, aging copper or early plastic supply lines, worn shower valves and roots working into older sewer laterals. Hillside lots can also mean long runs of pipe between the meter and the house.
Permits and gas safety
The City of Yorba Linda Building Division issues plumbing permits from City Hall at 4845 Casa Loma Avenue; call 714-961-7120. The city's building FAQ notes that YLWD may have its own plan submittal requirements for some projects. SoCalGas supplies natural gas. If you notice a gas odor, get everyone out of the house, then call 911 and SoCalGas at 1-800-427-2200 from outside.
How it differs from Riverside
Riverside homes mostly buy water from Riverside Public Utilities and pull permits from Riverside's Building & Safety. Yorba Linda sits in a different county, with Orange County Basin groundwater and a split between two water providers. When you call the number on this page, mention which provider is on your bill and what is going wrong, and you will be connected with an independent plumber who works in Yorba Linda. Pricing and timing are settled directly with that plumber.
