Winterizing problem

[Steve4020]

We are having trouble winterizing our 2013 Redwood. The antifreeze will go through the hot water lines but not the cold water line. We’ve never had this happen the years past. Any suggestions?

I am guessing the water heater bypass valve has been switched over? If it has then maybe the valve broke is side? If your in a very cold area you could consider blowing the lines out with air. Make sure its less then 50 psi regulated not high pressure shop air. then just treat the traps with antifreeze.

Thank you, we tried that and it worked.
