Backflow testing · Los Angeles County
Backflow testing, repairs coordination and retests in Westlake Village. First, check which program covers your assemblies.
Who runs your program
Your annual notice comes from the water supplier on your bill. Each one runs its own program, so here is how it works with yours.
Las Virgenes performs the initial inspection and annual testing of its customers’ assemblies with its own certified personnel, so check your bill before you book a tester. For assemblies outside the District’s program, and for repairs and retests, we test and coordinate the work.
Cal Water serves the Westlake area of Thousand Oaks, including many Westlake Village mailing addresses. It requires an annual test by a certified tester, and testers submit results through Cal Water’s mobile app after joining its tester program.
Exodus Water Services is based in Thousand Oaks. Certified Backflow Prevention Assembly Testers test reduced pressure (RP), double check, pressure vacuum breaker and spill-resistant vacuum breaker assemblies, and inspect air gaps, for homeowners, property managers, businesses and HOAs in Westlake Village.
We file the report the way your supplier requires, send you a copy, and when an assembly fails we coordinate the repair and retest it. In programs run on Exodus Water Compliance, reports are filed by scanning the QR code on the notice.
The process
FAQ
Your water supplier. Las Virgenes Municipal Water District serves the City of Westlake Village and tests its customers’ assemblies with its own staff. California Water Service serves the Westlake area of Thousand Oaks, where you hire a certified tester.
At least once a year, and again after installation or repair, by a certified Backflow Prevention Assembly Tester, under the State Water Board Cross-Connection Control Policy Handbook (section 3.3.3). Your water supplier mails the notice with the due date.
A failed assembly must be repaired or replaced and retested, generally within 30 days of the failure under the handbook (section 3.3.3), unless your supplier allows more time. We report the failure, coordinate the repair with a licensed contractor and retest the assembly.
It depends on the type and size of each assembly, how many you have, access, and any filing fee your supplier charges. Send us your notice and we will quote before scheduling.
Not for assemblies in the Las Virgenes Municipal Water District program, which tests them with its own certified staff. If Cal Water serves your address, or the assembly is outside the District program, you hire a certified tester.
Send us your notice or your last test report. We will schedule the test, file the report and keep your records current.
