Newly acquired 2000 vintage boat with original Jabsco head. Trailing her home, with the valve on "dry bowl" setting, I got seepage of unpleasant fluid back into the bowl. The holding tank only had a little in it. In the exploded diagram below, number 32 is described as a "joker valve", although I think that should be choker valve. Is this the culprit?
