Backflow Testing and Certification in Pleasanton

Backflow Enclosures and Freeze Protection in Pleasanton, CA
Above-ground assemblies sit in direct sun in summer and can freeze on cold nights. Even in mild areas, wrapping irrigation backflow devices before a frosty night is cheap insurance against a surprise leak. We install insulated enclosures, freeze blankets or heated cabinets based on your local climate. Enclosures also discourage theft, since brass backflow assemblies are a common target for scrap thieves. We choose enclosures with enough room for testing and service.

For high-hazard applications in Pleasanton, CA where toxic substances could contaminate the water supply, a reduced pressure zone, or RPZ, device is usually required.

FBL Plumbing is experienced with RPZ installation, making sure all components are correctly sized, positioned and set up according to state and local plumbing codes. Proper installation is critical for effective operation.
