How much direct or indirect heat could PVC take before it shows signs of
bubbling or melting? Over our bitter cold snap before Christmas, the
pipes froze to our new addition despite dripping water through the
night. My husband got the water running again by taking an inexpensive
propane torch and running it back and forth over the pipe. He didn't
see any signs of damaging the pipe, but he wondered if it would appear
suddenly and then be too late.
