Annual Backflow Testing in Knoxville

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 all set until next year.

Freeze and Heat Protection for Backflow Preventers in Knoxville, TN

Above-ground backflow assemblies are exposed to summer sun and winter cold. Before a freeze, homeowners here usually unhook garden hoses, close crawlspace vents and let faucets drip on outside walls. 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.

We test all common types, including RPZs, DCVAs, and PVBs, with accurate readings and careful checks.

Fire Line Backflow Testing in Knoxville

Fire sprinkler systems typically use double check or double check detector assemblies to keep stagnant water out of the public supply. These assemblies need regular testing, often coordinated with fire system inspections. We test and repair fire line assemblies and document the results. We can coordinate scheduling with your fire protection contractor.

Reduced Pressure Zone Assembly Service in Knoxville, TN

RPZ assemblies protect against high-hazard cross-connections at restaurants, medical offices, car washes and buildings with chemical feed systems. They have two check valves and a relief port that discharges water if a check fails. We install, test and rebuild RPZ units from Watts, Febco, Wilkins and Apollo. Proper drainage is designed for the relief port discharge.
