Fire Line Backflow Testing in Upland

These assemblies need regular testing, often coordinated with fire system inspections. We test and repair fire line assemblies and document the results. We can line up scheduling with your fire protection contractor.

Freeze and Heat Protection for Backflow Preventers in Upland, CA
Above-ground backflow assemblies are exposed to summer sun and winter cold. Freezing pipes are rare in most of Southern California, and many homes have exposed outdoor plumbing that would never pass in a harsher climate. Freezing can crack bodies and bonnets, while UV exposure breaks down plastic parts. We install insulated pouches, heated enclosures or lockable cages as needed. Protecting the assembly helps it pass testing and last for years.
Annual Backflow Testing in Upland
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.
