Residential Backflow Solutions in Spokane
For homeowners in Spokane, a backflow preventer is important for protecting against contaminants from garden hoses, irrigation systems, or cross-connections within your home's plumbing. FHN Plumbing offers tailored residential backflow solutions, from installing atmospheric vacuum breakers for hose bibs to more robust devices for whole-home protection. We make sure your family's drinking water stays clean and your home meets all local water safety rules.

Freeze and Heat Protection for Backflow Preventers in Spokane, WA
Above-ground backflow assemblies are exposed to summer sun and winter cold. Disconnecting hoses, insulating crawlspace pipes and covering hose bibs before the first freeze prevents most winter damage. 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.
