Backflow Enclosures and Freeze Protection in Martinsburg, WV
Above-ground assemblies sit in direct sun in summer and can freeze on cold nights. Freezing weather is a regular part of West Virginia winters, and pipes in exterior walls, crawlspaces and older homes are at real risk. We install insulated enclosures, freeze blankets or heated cabinets based on your location. Enclosures also discourage theft, since brass backflow assemblies are a common target for scrap thieves. We choose enclosures with enough room for testing and repairs.
