Anyone know. Place that stocks LARGE submersible well pumps. 4in size-- but 1hp. Our pump went out last night, dh took it apart & got it working, but of course broke the threaded PVC piece off inside the top of the pump. We have no idea how old the pump is so would prefer just replace it with a bigger one while he has the pump pulled. Any thoughts where to look, so far tried locke, lowes, atwoods, and a few other small farm hardware places.
