When I worked in Denver it seemed that many people winterized their sprinkler systems. Since then I worked in several places in Texas and it seems far less common. I'm guessing the main factor is how long a freeze lasts. Even so we had a pretty good freeze in Texas (Jan 2018) but most people still didn't winterize. I guess one way to look at it is if they don't call us to winterize they'll be calling us after the freeze to fix something. I guess my real question is in the poll below: should winterizing be something I talk about, advertise, show on my website in Texas?
