UPDATE!
So, I swapped in a new pump. Pretty much the same issue. Grrr
Going on a hunch, I took the cap off my winterization inlet and firmly plugged the hole with my thumb. The pump finally stopped. Clearly, there was enough of a vacuum, and associated Leake, to allow air to get slurped into the supply-side of the system, even with the valves in the "Use" position.
I even tested this a bit more by hooking the winterization hose up and submerging its end in a pail of water. Yep! It was sucking the tiniest bit of water.
The cap I was suing did not have the familiar little ball-valve-looking plug in the end of it which seems to prove a better seal than the one I was using... which did not have said stopped. Where the correct cap has gone, I cannot say.
So, I use a combination of a wad of electrical tape in the end, and some thread tape on the threads to seal the cap on a bit better, and my system seems to run as expected now. I'll go get the correct cap sometime soon.
I'll chock the price of the new pump up to the price of education. Air least I didn't;t have to rip the belly down on my camper (again!) I hate that.
Happy trails!
