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.

Half of the homes in Norwalk were built before about 1957. Houses from that era often still have galvanized steel water lines, which rust from the inside and choke flow, along with cast iron and clay drains that are near the end of their service life.

Around Norwalk, backflow testing and prevention typically runs about $85 to $285, before any permit, wall or slab access, or repairs to finishes. Plumbers cover all 3 Norwalk ZIP codes and nearby Santa Fe Springs and Artesia.
