If you have installed an aftermarket hose bib vacuum breaker, you need to winterize it.

Once the hose is removed, stick a finger inside and press up on the poppit inside; any trapped water should be released. Some units will require that you pull down on the inner workings to release the water.

The best way to protect your backflow assembly from our harsh Utah winter temperatures is to remove the unit and store it in a warm place.

Make sure to cover the open ends of the line that are sticking out of the ground with something to prevent dirt, debris, and insects etc. from entering the system.
