Irrigation Atlanta-Winterizations

What could happen if I don't winterize my irrigation system? If you don't winterize your system, heads and pipes can crack because of water remaining in the lines. If you are using a pump, the pump can crack too for the very same reason. It doesn't cost much to winterize a system. If you're thinking that we live in the south and dont need to do this-dont forget it freezes here too! If your goal is to save money by not getting it winterized, this could backfire. (Repairs could be costly and time consuming.)
