Backflow?

A backflow preventer, or backflow device, is designed to protect potable or drinking water from being contaminated. While there are a number of different applications for this device, it is most commonly found on a residential sprinkler system, located on the outside wall of the home. A backflow device provides protection of your drinking water from harmful contaminants that can be present in your sprinkler system, by allowing the water to only travel one way. To ensure proper operation, this device must be tested by a technician with the appropriate state certification.

• Pressure Vacuum Breaker, also known as a PVB, is designed to provide protection against back-siphonage of toxic or non-toxic liquids.  It consists of a spring loaded check valve which closes tightly when the pressure in the assembly drops below 1 PSI or when zero flow occurs, plus, an air relief valve that opens to break a siphon when the pressure in the assembly drops to 1 PSI.  Please see an example of a Pressure Vacuum Breaker below:
