What is a backflow preventer?

Backflow Prevention Devices prevent the flow of a liquid, gas, or suspended solid backwards, into the potable water supply.

What is Backflow?

Backflow refers to contaminated water that can flow backwards into a public water supply. In fire suppression systems, water can become stagnant, heavy metals and bacteria can contaminate the water. In irrigation systems, fertilizers, pesticides and other chemicals can pose a threat to the potable water supply.

Where are Backflow Preventers used?

Deringer Backflow Preventers are mainly used in fire suppression systems in commercial, industrial and residential buildings. Our smaller diameter backflow preventers are used in residential homes and sprinkler systems, as well as agricultural water supplies.
