B 331 Head and Webpage

[Stekon]

Two weekends ago I experienced a problem with the toilet (what a great subject to be writing about) on my 2004 B331. The dry discharge worked fine but when swithched to the wet discharge&fill position it emptied but did not refill. After pumping air for awhile I finally got it primed and working. I assumed I had lost prime while sailing. Again this weekend it occured while still in the slip. I had noticed that the the bowl was filled higher then normal when I opened the boat for the weekend. Anyway, before I go this weekend and start taking things apart, does anyone have suggestions?A note to Mark who is working on the "little Bs" webpage; can you somehow link any posings here on "little Bs" to the new website and send postings and questions from the new website to this board?Thanks for the help,Steve

Interested in hearing people's comments to this

I have a 2003 331 and, the first year, I had no problems at all. This year, though, I have been experiencing precisely the same issues as you mention: (1) loss of prime for the pump pulling water into the system, and (2) water filling the bowl over time.My suspicions are that the cuprits are: (1) the seal in the manual pump is no longer "tight" and is allowing air to seep past the seal, which causes the pump to lose its prime, and (2) that the joker valve is allowing water to seep back into the bowl from the discharge hose.I was thinking of just replacing the entire unit. I think a Jabsco is around $250.Peggy Hall would be the expert to ask about this, but, if anyone has any thoughts, I would like to hear them.Thanks

Same thing happened to me last year...

Peggy knows her stuff. As she advised, the problem is in the pump for priming and joker valve for back flow. Talk to you dealer. He should replace the pump as it has a year warrenty. If not, call Joe Foss at Beneteau. He also ownes a B331. Takes about 10 minutes. Pump lots of fresh water through the bowl to help clean out the outlet hose. Might even pour a little bleach in the water and let stand for 10 minutes to kill bacterial. Remove the intake hose, hose from pump to bowl, outlet hose and 4 base screws. When you remove the outlet hose, water will come out.As for postings from this site to the "little B's" site, I don't have the skills to interact with this site. However, I can create a link to BenteauOwners.netMark

Check out Peggy Hall's response on her forum page

I copied the original posting and my response, and sent them to Peggy Hall, on her forum page. She is THE expert on boat heads, holding tanks, odor problems, etc. Literally wrote the book on the subject (and I highly recommend the book, it covers more material than you would think possible). She has posted two responses - take a look.
