Backflow Preventers

A backflow preventer is a device that stops water from flowing back into the water supply line. It ensures that sprinklers, boilers, dishwashers, sewers and toilets are a one-way system, with water flowing out and not back in. Backflow valves, vacuum breakers and double check valves are used to prevent water supplies from being contaminated. Shop our supply of many different sized backflow prevention devices.
