Freeze and Heat Protection for Backflow Preventers in Ketchikan, AK
Above-ground backflow assemblies are exposed to summer sun and winter cold. Homes here commonly use heat tape, insulated chases, and supply lines buried deep below the frost line to keep water moving all winter. 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.
Annual Backflow Testing in Ketchikan
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.
Backflow Preventer Repair and Rebuild in Ketchikan, AK
Common failures include worn check valve rubbers, debris stuck under seats and relief valves that drip constantly.

Rebuilding usually costs far less than replacing the entire assembly.

A pipe burst at 11 pm and they actually answered. The plumber showed up within the hour, shut everything down, and had us back to normal the next morning. Could not ask for more.
