Check List: Backflows

A complete check list of all things "backflow".

A backflow is a device that allows water to go through it in one direction, but prevents it from going backwards in the opposite direction. Most backflow preventers are used to keep unsafe water from reversing flow and entering the clean water supply.

***You should have a backflow preventer on your irrigation system if your water comes from a “potable” (drinkable) source***
