Backflow Preventer Repair and Rebuild in Spokane Valley, WA
Common failures include worn check valve rubbers, debris stuck under seats and relief valves that drip constantly. We isolate the assembly, disassemble it and replace the worn parts with the manufacturer rebuild kit. Then we retest to verify it passes. Rebuilding usually costs far less than replacing the entire assembly.

Irrigation Backflow Preventer Installation in Spokane Valley
Sprinkler and drip systems are one of the most common sources of cross-connection risk because they sit in soil with fertilizers and pesticides. Many systems use a pressure vacuum breaker or a reduced pressure assembly installed above grade. We size and install the correct device and set it at the proper height. Insulated covers or enclosures help protect it from weather damage and theft.

We understand the demands of commercial operations and work efficiently to minimize disruption, keeping your business compliant and your water supply safe.
Fire Line Backflow Testing in Spokane Valley
