Western Municipal Water District — Backflow Compliance Requirements
Norco properties are served by the Western Municipal Water District. Like most water authorities in Riverside County, the Western Municipal Water District requires that backflow prevention assemblies be tested annually by a certified backflow tester. Failure to comply can result in delinquency notices and, in some cases, water service interruption. Southern California Backflow files test reports directly with the Western Municipal Water District on your behalf — so your Norco property stays compliant without the administrative hassle.

Our certified backflow testers serve Norco with fully equipped service vehicles and same-day availability in most cases. We perform pressure differential tests on all types of backflow prevention assemblies — reduced pressure zone (RPZ) assemblies, double-check valve assemblies, pressure vacuum breakers, and atmospheric vacuum breakers. After every test, we file the results directly with the Western Municipal Water District and provide you with a copy of the test report for your records. If your device fails, we carry common repair parts and can complete most repairs on the same visit.

Frequently Asked Questions — Backflow Testing in Norco
How often is backflow testing required in California?
Most water districts in San Bernardino and Riverside Counties require annual backflow testing. Some high-hazard connections may require more frequent testing. Southern California Backflow can confirm your specific requirement and manage your annual schedule.
How long does a backflow test take?
Most residential backflow tests take 30–45 minutes. Commercial or multi-assembly properties may take longer. We will give you an accurate time estimate when you schedule.
What happens if my backflow device fails the test?
A failed test means your assembly has a defect that prevents it from functioning correctly. We can repair or replace the assembly on the same visit in most cases, then retest to confirm a passing result.
Do I need to be home during the test?
Not always. If your backflow assembly is accessible without entering the building, our technician can complete the test and file the report without you present. We will confirm this when you schedule.
