Backflow Prevention

What is Backflow?

Backflow is when there is a flow reversal in a home’s potable water system, which can cause contamination and unsafe drinking water. Home water systems can be contaminated with chlorine from pools and hot tubs, soap and detergents, human waste, pesticides, fertilizers, household chemicals or other common contaminants through backflow. Water flowing backwards out of your home can also contaminate the public water supply.

Reversal of flow happens when there is a significant change in water pressure. Pressure changes can be caused by power outages, air trapped in the pipes, failure of a pressure regulating valve, a break in the water main, or a high demand on your water supply.

Water from your main supply should only ever flow into your home and never in the opposite direction. This can be achieved through the proper installation and maintenance of backflow preventers in your home.

Backflow Preventers

Backflow prevention devices ensure that your home drinking water stays safe and uncontaminated. A backflow preventer enables water to flow in one direction, but never allows it to flow the opposite way, thus preventing contamination.

Common Backflow Prevention Devices:

  • Double Check Valve Assembly (DCVA)
  • Reduced Pressure Backflow Assembly (RPBA)
  • Spill Resistant Vacuum Breaker Assembly (SRVB)
  • Reduced Pressure Principle Backflow Assembly (RP)
