Back Flow Testing & Repair

Backflow is the reversal of water flow through pipes due to siphonage or back pressure. A State Certified backflow device is required by law and protects your drinking water by preventing siphonage from your lawn back into your domestic water supply. If backflow occurs in your irrigation system, it can cause water contaminated with chemicals or even animal wastes to be suctioned backwards into your drinking water.

At Auto Rain Contracting LLC, we have certified backflow assembly testers on staff who have completed a rigorous training program and are certified by the State of Washington Department of Health to inspect, test and repair all backflow assemblies and devices. We provideĀ Washington and Idaho State certified backflow testing, repair and installation services to the Eastern Washington and Northern Idaho areas.
