Most of Yorba Linda gets water from Yorba Linda Water District and some residents from Golden State Water Company, and backflow rules come from whichever one serves your address; neither provider's program details were found in the sources reviewed here. For a test request, a failed device or a new install, call the number on this page to be connected with a local plumber in Yorba Linda.
Which water provider's rules apply to my house?
The City of Yorba Linda says most residents are served by Yorba Linda Water District, while Golden State Water serves some, and the provider depends on where you live. Golden State's part is its Placentia-Yorba Linda Water System. Backflow requirements, test intervals and report forms belong to the water supplier, and neither one's rules were confirmed for this page, so call YLWD at (714) 701-3000 or Golden State Water at 1.800.999.4033. Every California water supplier must guard its system against cross connections, so a request from either one is a real requirement.
Do hillside yards and horse properties change anything?
They can. Yorba Linda is known for extensive horse trails and hillside areas on its eastern side. Sloped yards often use pressure vacuum breakers, which have to sit above the highest sprinkler head to work, and a device placed too low or damaged by a landscape crew may need to be moved. On horse properties, hoses left in troughs and wash racks fed by long hoses are common cross connections. A vacuum breaker on each spigot or an air gap at the trough fixes most of them; higher hazards call for a tested assembly.
Will I need a permit, and does the water district get involved?
The City of Yorba Linda Building Division issues plumbing permits, and its building FAQ notes that Yorba Linda Water District may have its own plan submittal requirements that affect projects. For a new or relocated assembly, check with both. The Building Division is at City Hall on Casa Loma Avenue, 714-961-7120. Water quality can matter too: Golden State Water's Placentia-Yorba Linda system lists hardness averaging 11.0 grains per gallon, and scale like that can keep a check from sealing.
A local note
Yorba Linda's median home was built around 1984, so many irrigation systems and their original vacuum breakers have been in service for decades. If a sprinkler device sprays when zones start or drips all day, it is usually worn seals, and a rebuild or replacement is a routine job. Tell the plumber which provider bills you so the test report goes to the right place.
