Hi all - I've been reading the frozen lines posts as we've have very cold single digit temps this weekend in Oklahoma. Im hooked I into city water and all insulated and its working. I have the Yeti heaters and heated lines on my Road Warrior. I have frozen lines in the hot and cold water in the kitchen. Then the aft toilet and sink are frozen up to. I don't know enough about how this plumbing works to find the lines to unthaw and wrap the lines. I have the floor heat on, space heaters and a 110 reflector plugged in in the basement. Any clues are appreciated? Thank you!
