My final post on this thread, I am happy to say I am DONE! New head, all hoses and Y-valve replaced and NOTHING LEAKS!! One final "F You" from my plumbing system to me, however. Doing the test flushing, valve open to the holding tank & pressure was building to the point that the head pump handle wouldn't go down. Hmm? The only thing I could think of was that the water was somehow going into the hose which leads overboard, but that seacock was closed, so thus the pressure build-up. But how, when the valve handle is clearly pointing to the tank side? Well, contrary to everything I've ever learned about valves where the handle goes in the direction of the flow, Jabsco apparently likes having the handle pointing to the side that is BLOCKED! Put the valve back together, pointed it to the overboard discharge hose (thus blocking it) and Voila, works like a charm. I'm getting the feeling that Mr. Shields and Mr. Jabsco do this stuff on purpose.
