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.

Backflow Testing and Prevention in Hidden Hills: What To Know Locally

Hard imported water and homes built on concrete slabs drive most calls here. Many homes sit on concrete slabs, which is why slab leaks are one of the area's most common emergency calls. Half of the homes in Hidden Hills were built before about 1973. Homes from that period commonly have copper supply lines paired with cast iron drains, and some still have sections of the original galvanized pipe, so a repair can turn up mixed materials. About 27% of homes here predate 1960, so older pipe is still common.

Around Hidden Hills, backflow testing and prevention typically runs about $85 to $285, before any permit, wall or slab access, or repairs to finishes. Plumbers cover Hidden Hills and nearby Calabasas and West Hills.
