Irrigation Backflow Preventer Installation in Butte
Sprinkler and drip systems are one of the most common sources of cross-connection risk because they sit in soil with fertilizers and pesticides. Many systems use a pressure vacuum breaker or a reduced pressure assembly installed above grade. We size and install the correct device and set it at the proper height. Insulated covers or enclosures help protect it from weather and theft.
Freeze and Heat Protection for Backflow Preventers in Butte, MT
Above-ground backflow assemblies are exposed to summer sun and winter cold. Pipes in exterior walls, crawlspaces, cabins and vacation properties are especially likely to freeze during long cold spells. 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 Butte
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.

Trust us to maintain your Febco device to factory specifications so it keeps protecting against backflow events.
Fire Line Backflow Testing in Butte
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.

A well-maintained backflow preventer can last 10 to 20 years or more. However, factors like water quality, exposure to weather, and the type of device can affect its lifespan.
