Thanks to all for your opinions. The weather is good for varnishing so it has priority at the moment. The boat is not a live aboard so it doesn't get that much use. The problem has been with me for some time now and I have had the pump assembly apart, put it back together, it worked, maybe the top gasket wasn't sealing ?? Then it quits again. As we all know the intermittent problems are the most difficult to solve. It may work perfectly and then a half hour later fail to work. I had hoped I could tap into the experience of somebody who also had this problem. The toilet is about 5 years old came with the boat - no manual. I downloaded what would appear to be a similar one. Part 18 is "Top Valve Seat" on it. # 17 is the Seal Assembly at the pump handle. There might be a very slight leak there. Hmmm? Perhaps Peggies solution will save some hair.

It is part number 18 on your parts diagram of your toilet manual. I would try that before completely rebuilding, but, as Rudy sez, a rebuild is easy > on this toilet.
