There are several effective methods for winterizing or draining water from your irrigation system to prevent damage during the freezing winter temperatures…Manual Drain Method, Automatic Drain Method and Blow Out. The preferred method is blow out as it is the most effective in clearing water from the irrigation pipe and valves. It is also equally important open and close the ball valve (if so equipped) to allow any water to escape the back flow device and prevent damage to your back flow device which is one of the more costly repairs to your irrigation system.
