Helping a buddy replace his submersible pump. Have no idea how old the well or the old pump is. It is a 1/2 hp, thats about the only thing we know. The pitless adapter is not one that I am familiar with. It has an 1-1/4 hole in the center for the T handle and is the size of the well casing.In other words, it's almost like a "plug" type of pitless adapter. We got the T handle screwed in but it will not come loose. The pitless adapter has "slots" on either side. Is there a "trick" to this style or is it just being contrary? I was going to try a hydralic jack on either side of the T handle and see if that breaks it loose..............is this foolish?
