Bath tub drain of second floor bathroom froze in our 1 deg. winter today.
Drain pipe travels down outside wall into basement. Is there a small clog somewhere that would allow water to pool so it could freeze? I cant't see running water freeze in a 2 in. pipe. What do you think about spraying GREAT STUFF into floor cavity where pipe enters wall in basement? Should I just wrap exposed pipe in fiberglass?
