    Galley Sink Drain Odor

    When we were out this past weekend we noticed that there's a foul odor coming up the sink drains in the galley. Anyone have a good suggestion for how to remedy this without replacing all the drain lines? I suspect it has to do with sea water back-washing into the drain thru-hull and the little bit that gets in there sitting and creating the smell. Any advice would be great!

    This problem occurred when we had the 490. After making sure that there are no blockages using a snake, we blocked the through-hull for the drain line and added a hefty dose of Zaal Noflex Digester and topped up with water. It took a couple of treatments, but it cleaned up all of the odors in two days.

      Is there anyway to reroute it or raise the thruhull? On my 32xx it was a very short and all downhill run, so no way for water to get trapped anywhere.

        It would be difficult to change the drain line without much reworking. I think one of the main issues here is that there are 2 sinks in the galley, and the cross tube between the two drains gets gunked up fairly quickly.

      Great suggestion. As luck would have it, I just got 4 bottles of Noflex last week to use in the holding tank. I'll give this a go! What did you use for plugging the thru-hull?

        I used aluminum tape - the really awkward stuff where the backing has to peel off. It adheres really well to itself and almost anything else where there's no oil or grease present
