Annual Backflow Assembly Testing
Yearly testing keeps your assembly compliant with California Code of Regulations Title 17 and your water district. We test RPZ, double check, and PVB assemblies, file the certificate, and remind you when next year's test is due. Most residential tests take 20 to 30 minutes.
View service 02Irrigation System Backflow Testing
Irrigation lines are a common source of cross-connections. We test your pressure vacuum breaker or RPZ, check for leaks and frozen components, and make sure your sprinkler system is not putting your drinking water at risk. We work with all major brands.
View service 03Backflow Test and Repair
If your device fails, we do not just hand you a report. We diagnose the problem, whether it is a stuck check valve, a bad relief valve, or worn O-rings and gaskets, and repair it on the spot. Then we retest and file the passing certificate.

New installation or replacement? We size and install the right assembly for your property, whether it is a reduced pressure zone assembly for commercial use or a double check valve for irrigation. We pull permits and handle the inspection.
