Backflow Prevention

Why do you need a Backflow Preventer?

Backflow prevention keeps your drinking water safe and separate from the water that flows outside to your irrigation system.  There are different types of devices for specific applications. The type required for your system will be determined by the local plumbing code.  Green World uses licensed plumbers to install and service this part of your system and also gets any permits where required.
