I now have a dead head. It is getting next to no suction and is pumping far more air than water. I'm surmising that the seals and valves need replacement.
It's a 1981 boat, and the head has a label saying Wilcox Crittenden, no model number visible. I called the firm, which was quite unhelpful. They don't have rebuild kits for older heads. Now some of the parts are probably unchanged and they might be able to piece something together for me, but that's assuming I can get them some kind of model number.
Any suggestions here? The head is in otherwise perfectly fine condition, and I'd hate to replace the whole thing if it's a problem as minor as a few valves and seals.
Any help pointing me in the right direction would be greatly appreciated, seeing as my wife is now refusing to go sailing until the situation is fixed. ;-)
Thanks,
