Hi Peggy: I do know the difference between a Y valve and the lever on the pump for dry flushing and wet flushing. I did rebuild the pump on a Jabsco head for my Catalina 25. You are right as far as replacing the head rather than rebuilding. The Y valve is located of effluent hose in the cabinet under the sink. Could the Y Valve be stuck in a position where the effluent could not be pumped to either the holding tank or through hull? As Paul mentioned, I have tried to pump with the lever in both positions and still nothing.

Y-valve could be the culprit...
If you think you're going overboard, but the handle is somehow reversed and the seacock is closed, Nothing will move. If that's not the problem, are you feeling any resistance--back pressure--when you pump the head? 'Cuz that would mean either a blockage in the line or--if you're trying to pump into the tank--that the tank vent may be blocked. Now that we've established that you DO know the difference between the dry/flush lever and a y-valve (hey...you'd be amazed at some of the things I hear!), are you absolutely certain that it IS a y-valve and not the flush water intake--or the discharge--thru-hull's seacock? Wouldn't be that hard a mistake to make...and your comment that there's a metal rod sticking up that looks like a handle should go onto it is raising all kinds of questions in my mind about what it really is...'cuz no y-valve I've ever seen has anything like that...just a hub and/or a nut for the handle. And not all of 'em even have removable handles. Please don't think I think you're a total doofus...but without being able to see your installation, I'm flying kinda blind...even trying to diagnose your problem psychically
... We can figure it out, but it just may take a little doing.

Mickey, is the configuration on the boat the same configuration as the pages from the manual that I sent to you? If not, maybe it has been retrofitted by the previous owner.
