    Marine Head Blockages

    Hi folks! Have a 2000 2455SB, my first boat with a head and it blocks up when my 6 year old takes a dump in it let alone an adult. It was fitted with an electric pump and macerator replacing the manual hand pump. I'm new to this game and the toilet itself and the piping all seems rather small. Is this a common issue that you just have to learn to live with or is there an alternative so I can remove the "toilet hazards" from my pre-sailing safety briefing...

    Thank you! Mark - Captain and Chief poo technician

    Paper is your enemy. On some yachts they say not to put anything down the toilet that hasn't been through your human waste system first....
    Seriously, small electric macerator pumps hate paper. One or max two sheets, and not 10 ply!
    A lifetime of racing everything from dinghies to world girdlers, but one of those lucky people who just love being afloat. So .... when the body doesn't work like before, it doesn't mean staying ashore.

      Thank you, yes we have a separate bin for paper. The challenge seems to that sometimes it takes a while to do the grinding, and at the same time it's filling with water (one button does both fill and pumpout) and the bowl gets to the point of overflow so I need to scoop out the water before doing more grinding... I've closed the intake seacock 3/4 to restrict the filling flow which has worked but isn't ideal.

        We do a little, flush, repeat until the jo is complete. Next, as to tp, We buy the 2-ply Marine & RV stuff that cost about a buck more than the super cheap one ply that al works. I've also had salt buildup on the impeller and a shrimp clog the inlet.

          Remove the outlet fitting on the toilet and clean it, check the one way rubber valve and clean or replace it if it does not seal at the outlet of it.
          Sometimes the outlet hose gets build up inside.

              I have had quite a few heads and tried heads on numerous boats, manual, electric and vacuflush, never really had a problem until the day some lady decided to drop a tampon into the grinder. Needless to say that put a halt to the head until I took it apart and removed the culprit. That being said there is definitely something jammed up somewhere in the lines as it should flush quite easily.

                I always tell guests that if they plug up the toilet, they will be using a bucket, and they will need to empty it and rinse it.
                Only while offshore! Otherwise I send them up to the harbormaster restrooms for serious business!
