Why Is My Backflow Preventer Leaking?

This device is designed to leak a bit during a system shutdown when the watering cycle stops or is turned off. However, it should not be dripping constantly. If you notice that your backflow preventer is leaking all the time, you should call in a technician to diagnose and fix the problem.
