Backflow Preventer Testing in Rancho Cucamonga

We use calibrated equipment to check the device, making sure it properly prevents reverse flow.

Irrigation Backflow Preventer Installation in Rancho Cucamonga
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 and theft.

Annual Backflow Testing in Rancho Cucamonga
Most water providers require backflow assemblies to be tested at least once a year. Our certified testers connect a calibrated differential pressure gauge and check each check valve and relief valve. Test results are recorded on the provider's form and submitted for you. If the assembly passes, you are done until next year.
