Backflow Preventer

Backflow preventers are devices that are installed on your home’s water pipes that only allow water to flow in one direction and not the opposite. Their purpose is to prevent drinking water from being contaminated with other sources because of backflow. The most common is the pressure sprinkler vacuum breaker (PVB. These are all installed in the water system immediately after the isolation valve.

If a backflow preventer goes bad, water can smell bad or have a dirty, brown color. The flow of water can be different than usual, often much slower, or water may be draining slower than before. If you notice any of the above, contact Oak View Mechanical.
