A pressure vacuum breaker (PVB)

is a type of backflow prevention device which is installed on potable (drinking) water lines to protect against non-potable (or contaminated) water entering the potable water supply due to back siphonage and/or back-pressure.

Backflow prevention devices such as PVBs are a health and safety standard regulated by the Uniform Plumbing Code.

Most homes, especially newer homes, have backflow prevention devices.

A note of caution in these “cold” winter weeks here in the Phoenix area:  Pressure vacuum breakers must be protected from freezing when installed outdoors.

Your PVB has plastic parts that will split/crack in freezing temperatures. Be sure to cover your PVB when temperatures are predicted to drop below freezing.

Zach installed this backflow prevention device at a home in Phoenix recently when the homeowners decided to install a new sprinkler system.  The water service riser was replaced at the same time.  Nice work, Zach!
