Despite having a heated well pump house and heat taped pvc lines the two days of 5F and no power did my pvc lines in. Trying to repair myself as plumbers are at least a two week wait. Plus for now all stores are OUT of anything pipe related. It is 1.25 pvc and the usual fittings to go up to top of water tank. But I don't know what the fitting is that I need to buy where the pipe goes into the tank. Its a large white fitting going into a black screw on fitting. I don't know what these are or are called to order one. Thanks in advance We need water. Tank is dry.
