What is a backflow preventer?

A backflow preventer’s purpose is to protect your drinking water from the possible contaminants from your lawn. Think of the how an inflatable raft works, you can blow air in, but no air can escape. The backflow works the same way, water can feed into your sprinkler system, but it cannot return back to your drinking water. This is a required device for ALL installations in Northern Virginia.
