Water providers generally require assemblies to be tested once a year by a certified tester, with the results filed, and commercial properties and homes with irrigation or fire lines are the most common cases.

Some homes from the late 1970s to mid 1990s used polybutylene pipe, which has a history of failing and is worth checking for.

Around McFarland, backflow testing and prevention typically runs about $75 to $250, before any permit, wall or slab access, or repairs to finishes. Plumbers cover McFarland and nearby Delano and Wasco.
