Q: Why does my backflow preventer keep dripping?
A: Your backflow preventer will need periodic maintenance (which is simple to do and can be done by the homeowner) in order to properly function.
Small sediment (a grain of sand) can get stuck between the top rubber gasket and cause the backflow preventer to drip. All you need to fix it is a wrench and a couple of minutes!
Feel free to ask one of our irrigation technicians to show you how to properly clean the backflow preventer the next time your system is being serviced!
