I took one of my propane heaters over to my neighbors whose water system was frozen up in his pump house this morning. Unfortunately most of the piping was already broken. We got everything disconnected from the pressure tank and used the propane heater to thaw it out. Then we removed all the rest of the piping from the well and the underground line to his house.
His SIL is a plumber and was coming over to rebuild everything with new pipe, fittings, filters, etc. I suggested he get some heat tracing to go around all the piping then foam insulation over that.
He should have water this afternoon.
