Winterize Your Irrigation System
The process of winterization is meant as a preventative measure to help reduce any possible freeze damage to
irrigation components. Here we provide some basic steps on how to do it yourself; for guaranteed results, we
recommend having a professional to winterize your
system for you.
Locate the Double Check or shut off valve.
If your system is a Choate USA system your Double Check or Shut off valve should be
in a valve box next to your water meter. If you have a Pressure Vacuum Breaker (PVB)
you will need to shut off the Shut off valve and the PVB.
Turn the water off.
This is done at the Backflow Prevention Device / Double Check or Shut off valve for
your irrigation system.
Open the Petcocks.
Manually open all of the valves in the system.
This is done to release water pressure in the system.
Turn your controller off.

Hunter ET System
Drain or blow out the water of any irrigation components that may freeze.
PVB’s are especially prone to freezing. Failure to properly winterize them will often
result in damage. Placing heat tape, a hot box, or a hot box rock on the PVB will also
help but cannot guarantee that freezing will be prevented.
