One more thing I forgot... When my pump turns on the drop pipe (Poly) lowers by about a 1/2" into the well seal then comes back into place. It barely moves when the pump shuts off. Is that a normal amount of torque? The pump is hanging from a 3/16" stainless wire which is anchored to a pulley system connected to the roof. Anyway, it seems that after thousands of cycles it would cause some wear and tear on the PVC pipe that its connected to. Or maybe I worry too much.
