I see something from 2001 where the handle broke off the Y valve. I had that happen and somehow figured out how to replace it with what I think is a Bosworth, which has been fine. But now it's becoming very hard to turn and I am afraid of breaking this one. I looked on line and couldn't find anything about disassembly but opened it up- handle off, three bolts that hold the cover. then there's a little set round piece of plastic and there's a rubber ring exposed. but I very gently pulled on the plastic and it had no give I didn't want to run the risk of it breaking, and not having an operating head. so put it all back together.
tried lots of fresh water flushes, and alternated 2 gallons of vinegar, turning the handle until a lot of resistance, so that it was flowing into the holding tank, but I suspect it's not all the way as the arrow doesn't line up direct to the tank hose. but now it's has a definite squeak when I try to turn the valve.
gee, isn't cruising fun?
Randy : I'd just go ahead and replace it with a new "Y" valve.
You know that if you get the old one working again, it'll probably break or freeze up at just the WRONG time - like most head parts do!!
Those few $$ for a new one ain't worth the aggravation! A thought
wst marine had one in stock so picked it up, but I think I'll put it off till another day. I spent 3 hours contoring my 6'4" frame into that little hole of a door, reaching in to loosen the clamps and pull the macerator off the bulkhead, but the hoses are so dog gone hard to get off, I gave up for now.
Randy : Get a heat gun to warm up the hoses and they'll put off the fittings - easily!! A thought
Or sometimes a hair drier will work in a pinch.

Randy : As Mike points out "heat" is the key.
Harbor Freight has heat guns on sale for about $10!! You probably can't buy a hair dryer for that price?
