A backflow preventer is a plumbing device that stops water from flowing backward into the clean water supply. It acts like a one-way gate, allowing water to move in the correct direction while blocking reverse flow.
There are different types of backflow preventers depending on the plumbing system and the level of protection needed. Common examples include:
- Atmospheric vacuum breakers
- Pressure vacuum breakers
- Single and double check valve assemblies
- Reduced pressure assemblies
- Air gaps
A properly installed residential backflow preventer helps protect drinking water and household plumbing.
