Hello all and thank's in advance for any information. I bought a piece of property for seasonal use. The well is 150ft. deep. The pump is at 145ft. About 20ft. from the well is a small building containing the tank, it is also above the top of the well. The tank is galvanized Franklin. 1" plastic pipe underground from the well to the tank. Heat tape from the tank house down the hole that the 1" pipe and pump wiring emerge from. My question, When I drain the tank for the winter will the water siphone back down the pipe into the well? If this is the case and I plug in the heat tape, can it cause damage to the empty pipe? I would prefer the 1" pipe to be empty and not to have to use the heat tape as winter access for maintainance will be difficult. Thanks for any info.
