Honey had the same issue last summer, the culprit was a faulty joker valve. Jack Fitzgerald C&C 39TM HONEY US12788 In a message dated 7/11/2013 11:28:59 A.M. Eastern Daylight Time, stevanpla...@gmail.com writes:
I never really understood the loop in the discharge line. If your discharge line feeds the tank on top of the tank, in the middle, how would the contents of the holding tank get back into the hose? I understand not everyone's setup is this way ... and I'm only chiming in because I'm about to plumb mine the way I described, I hope I'm not screwing something up. I don't like the idea of a vented loop in my discharge, complicated .. and potentially gross. As to Peter's problem, my guess is the hose goes up before it goes down again, so there are always contents in the hose. Your joker valve isn't working well so the contents of the hose backwash into the bowl (IMO another argument in favour of ditching the vented loop in the discharge). The fix would be to fix/replace that joker valve and to make sure to pump the contents well clear so that if there is any backwash it's .. cleaner. I've never actually done my business on a boat before so I'm not the best person to be giving this advice, much less redesigning and installing my own system so if I'm off base I'de like to know!

The bowl half fills, requiring a “dry” flush to clear it again. Upon arrival, we had the holding tank pumped out, but haven’t tested since. I suspect it has much to do with hoses and hose placement. If the boat is sitting, everything is fine. Peter Delean North Bay, ON Drifter II C&C 30 Mk1 ____________________________________ No virus found in this message.
