Protect Against Backflow With Reliable Preventers
Protect your drinking water supply with a backflow prevention valve from Stockpile Express. A backflow preventer uses pressure to move water forward in a single direction, keeping contaminants from re-entering your supply. Explore our selection and find standard and reduced pressure backflow preventers, as well as backflow preventer assemblies that install in succession to each other for optimal water transfer. We offer high-quality, reliable backflow prevention valves from Watts, Caleffi, and other trusted manufacturers. For maximum performance, your backflow preventer should be checked at least once a year.
