Yeah, my "summary" was wrong about he suction side - one suction line, installed to whichever pump is being used with the other plugged, or simply a second pump waiting for suction & discharge lines to be swapped along with the electrical. Parallel indeed requires valving to function.

Yep, I understood and it's a good idea. Right now he's set on getting the pump out of the tank, but I'll pass on that idea, too. If he knows where the pump sits on the tank after all this time it would be an easier approach! Thanks for clarifying your thoughts!
