To those AGP owners who have ball valves on your returns - do you use winterizing plugs in the returns as well, or just shut the valve off and go with that? I installed ball valves on my returns this year, and was wondering if I needed to go ahead and plug the returns and leave the valves open, or just close the valves and hope they don't freeze up and crack. We usually don't get that much freezing weather around here, but we can have hard freezes from time to time.
Thanks in advance!
