[C38] Head

Wed Oct 19 11:23:53 EDT 2011

Don't know about you other boaters but in the San Francisco Bay the Coast Guard cites boaters who do not have their through hull wired shut.  It is not legal to dump sewage within about 10 to 25 miles of the coast.

  There is a two way "y" valve between the holding tank and thru hull. One branch to tank and other to thru hull. The macerator also exits thru hull. The deck pumpout hose drops straight down behind the vberth cabinet. With y valve in tank position it allows sewage to be pumped from tank.

    Max,  No, I definitely don't have a valve between the macerator and the holding tank, but I can't remember where the deck pump out hose attaches to the holding tank.  The deck pump hose must go directly to the holding tank, because to pump out all I do is open the deck fitting and it works.

    Steve O., You're right. I had to get paper and a pencil and made a diagram, now I get it!! LOL 
    Do you still have the valve before the macerator for the deck pump out fitting???

      Max,  There are 3 valves involved:
      1)  The 2 way valve that directs the head discharge overb'd or to the holding tank.
      2)  The macerator discharges to the overb'd hose via a tee with a ball shut off valve just before the tee.  This valve keeps sea water from leaking back through the macerator pump into the holding tank.
      3)  The overb'd through hull valve
      Normal operation, where allowed, is discharging the head directly overb'd.  The 2 way valve handle is up with the discharge overb'd and the macerator valve closed.
      For discharging to the holding tank, the 2 way valve handle is down, and the macerator valve is closed.
      To macerate, the 2 way valve is mid position (no flow from the head or worse no flow back into the head) and the macerator valve is open allowing flow overb'd. 

      I think a simple diagram would of explained this better.
      Cheers, Steve O

      Steve, 
      How is that Tee for the holding tank and head discharge working??? How many valves have you installed??? I already have one to select if the head discharge goes overboard or to the tank. I'm not sure if this is standard setup or not...

      Regards,

        Good job Steve!  Something to think about- the upper aft portion of cabinet interferes with a person putting their head directly over the sink.  One of my future projects is to recess that aft cabinet portion outboard to allow more headroom, which would also allow more options for lighting.
        You mentioned in an earlier thread about plugging through hulls to obtain that additional fractional knot.  What we did when we had the bottom peeled and vinylester applied was to:
        1. Plug the head sink drain through hull and run the drain aft and tee it into the galley sink drain.  It works well, but the sink can still overflow on a starb'd beat.  So it didn't solve that problem- I still have to closed the galley drain cock.
        2. Plug the macerator drain and tee it into the head "direct overb'd" with appropriate valving.  This works great- I never understood why you would have two large overboards, side by side, when a tee would work for the same dirty water.
        The biggest benefit from the above rework was the vinylester bottom- the boat definitely float higher!  I didn't go into the peeling operation for that reason though, I wanted get rid of the blisters.  My boat was like small pox all over and this kept me from sanding the hull at the bi-annual haul outs. 
        Thank you for the pictures, as it gives me insight of what I'm up against in reworking the head cabinet.

        Here are the pics after taking out the counter top intersting find in the process.   looking at the sink in the upper left corner of the counter top is where the water pools you can see in the pic a cut out that lead straight to the the salon bulkhead,  any water that accumulates from a shower, the sink or the head sweating runs right down the back of the bulkhead and under the forward cushion.   I always thought my chain plate was leaking and sealed and resealed numerous times.  Took the counter top out of the boat and with it went the musty boat smell, next time on the boat no smell.   The counter was wet in the same upper left corner and some mold.  sprayed with mold killer will paint and reinstall,  thinking that I will run a piece of teak trim along the counter top and the bulkhead sealing it to capture any water on the laminate counter top and in the far upper left corner cut in a flush to the counter top through hull type fitting so any water accumulation can drain into the bilge.   Other idea was to do the same trim detail but install laminate directly over the gelcoat cabinet, make a spacer for the chainplate mount and not worry about wood any longer.   Thoughts or comments please

        Max, the last pic is of the bulge in deck you asked about earlier.
