Just remember that once you get it working, you need to winterize
before the
ground freezes. The basic method is to turn off the supply and blow
all the water out, a zone at a time. You can do it yourself with a
decent shop compressor, or you can pay for a service to do it for you.

He lives in AZ. No need to winterize. Same for me in Texas. I run my
sprinklers once or twice in the winter if we go through a long dry spell.
