Help. Frozen pipes have been heated in 50+ degree housing for the last 10 hours. Tank charge reading 36 PSI (bladder tank), pressure gage reading 40 psi, open valve next to gage and no water. Pressure gage was originally reading zero prior to application of direct heat on pipe. Am I looking at a bad gage? Pipe still frozen after all this time? Pump eventually burned out (no breakers popped) Any ideas?
