Most Yorba Linda homes are served by Yorba Linda Water District and some by Golden State Water Company, so a private well pump is rare here. Hillside homes can have booster pumps, though, and a plumber can test those or track down a regulator, leak or fixture problem on public water. Call the number on this page to be connected with a local plumber in Yorba Linda.

Which utility serves my Yorba Linda home?
The City says most residents are served by Yorba Linda Water District and some by Golden State Water Company, and that the provider depends on where you live. YLWD reports that about 85 percent of its supply is local groundwater from wells drawing on the Orange County Groundwater Basin, with about 15 percent imported from the Metropolitan Water District. Golden State Water's Placentia-Yorba Linda system blends treated basin groundwater with imported Colorado River and State Water Project water. Those wells are utility equipment, and most Yorba Linda homes are on utility water rather than private wells.
Could my problem be a pump at all?
Possibly, if your home has a booster pump. Yorba Linda has hillside areas on its eastern side, and some elevated homes add a booster pump and pressure tank to lift water to upper floors. Those systems fail the same ways well systems do: a pressure switch that chatters, a tank that loses its air charge, a pump that runs constantly or trips its breaker. Without a booster, weak pressure usually means a worn regulator, a leak on the line from the meter, a partly closed valve or scaled fixtures. City-stats.com puts the median year built at 1984, so plenty of original regulators and valves are due for attention.
Does the water itself play a part?
It can. Golden State Water reports an average hardness of 11.0 grains per gallon for its Placentia-Yorba Linda system, with a range of 3.92 to 17.5. YLWD lists its own hardness figure in its annual water quality report. Hard water leaves scale in aerators, cartridges and pump check valves, so a slow decline at one or two fixtures is often a cleaning or cartridge job.
