What is a BackFlow Device?
(Wikipedia Definition & Diagram)
This is a device that should have been installed with your irrigation system that, when functioning properly, prevents non-potable or “waste” water from mixing with your potable or “clean” water supply that enters your home.
Backflow Prevention Devices
- Double check valve (DCVA)
- Pressure vacuum breaker assembly (PVB)
- Reduced pressure zone device (RPZ)
In some cities both Residential and Commercial properties have to be inspected every 1-3 years. We expect that in the near future all properties will require backflow device testing on a yearly basis.
