A pressure vacuum breaker (PVB) is a type of backflow preventer that protects your home’s drinking water from contamination. It stops dirty water—like irrigation runoff or hose water—from flowing backward into your clean water supply. It’s often required by law for sprinkler systems and outdoor faucets. At Done Plumbing, Heating, Cooling & Electric, we install, inspect, and repair PVBs to keep your system compliant and your water safe. All of our work is backed by our 100% satisfaction guarantee, so you can trust it’s done right the first time.
