Backflow Preventer Repair and Rebuild in Dunwoody, GA
Common failures include worn check valve rubbers, debris stuck under seats and relief valves that drip constantly. We isolate the assembly, disassemble it and replace the worn parts with the manufacturer rebuild kit. Then we retest to confirm it passes. Rebuilding usually costs much less than replacing the entire assembly.

Whether you are installing a new irrigation system, fire suppression system, or need to replace an outdated device, HGR Plumbing handles professional backflow preventer installations.

Proper installation is key for effective operation, and our certified plumbers make sure your new device is correctly fitted, tested, and compliant with all Dunwoody standards.
Freeze and Heat Protection for Backflow Preventers in Dunwoody, GA
Above-ground backflow assemblies are exposed to summer sun and winter cold. Before a cold night, disconnecting hoses, covering hose bibs, and letting a faucet drip are usually enough to prevent a burst line. 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 longer.
