Murrieta Plumbing Backflow Prevention Testing Service

Backflow prevention is a plumbing safety plumbing contractor Murrieta requirement that protects the public water supply from contamination by preventing water from flowing back into the municipal system from private properties. California requires annual testing of backflow prevention devices on commercial properties and many residential irrigation systems. A backflow preventer allows water to flow in only one direction. When pressure drops in the municipal supply, a properly functioning backflow preventer prevents water from the private system flowing back into the public supply. Without this device, contaminated water from irrigation systems, industrial processes, or any private water use could enter the drinking water supply. Murrieta Valley Plumbing performs backflow prevention testing and certification for commercial properties and residential irrigation systems throughout the Temecula Valley. Testing involves checking the device's internal check valves to confirm they hold against reverse pressure.

Failed backflow preventers are replaced with devices appropriate for the specific application. Different protection levels, designated as RP (reduced pressure zone), DC (double check valve), and PVB (pressure vacuum breaker), are required depending on the potential contamination hazard of the application. Annual testing is required for most commercial backflow devices in California and must be performed by a certified tester who submits results to the local water authority. Murrieta Valley Plumbing's team includes certified backflow testers who complete the testing, provide the required documentation, and submit results to the appropriate authority.
