    Location for holding tank for new head

    Has anyone tried installing a new holding tank for the head.
    and if you did where did you put it.

    I pulled the head in favor of a porta-potti. We're only going to use #66 for weekend excursions anyway, so the cost and complexity of a holding tank system is too much.

    Do you live in Boston, or one of the burbs? I live in Falmouth.

    We too are weekend warriors on the Adele M, and converted to a porta-potti setup a few years ago. No odors, no leaks, sanitary and simple.

    Click on the seach button and try "head" "holding tank" and "potty" you should find some useful posts.

    Holding tank underneath starboard V-berth.


    The hoses for pump out and venting lead up to the deck.

    The first year I had my boat I put in a new marine head. I made
    a shelf that hung from threaded rods in the port V-berth locker.
    A 5 gallon Todd will fit easily under here. Where it gets tight is when
    you try to fit the 'Y' valve and a manual pump for overboard
    disharge. I did it, it worked, but I will say that working with
    the short lengths of sanitation hose in the confined area is hard
    on the hands. Try dipping the ends in boiling water to soften them when slipping the hose over fittings. The systems largest obstacle remained where to locate
    the vented loop. Mine was just above the water line, I think, but
    dangerously close. One day, after recieveing clear instructions, on where to
    turn the valve my wife proceeded to pump the tank out through the vent,
    the horror! I went to a portapotti the next season, simple, no smell, you don't
    need to be a plumber to use it and most importantly no back-siphoning.
    Cheers B.

    ...and don't forget Geoff who put the tank in underneath the 'forward cabin sole.' With the head right on top. Not quite having a complete picture of his solution, it does seem that raising the deck here in the V-berth area certainly has nothing to do with losing any headroom. Pumpout might be a problem, I'd guess. (I mean just how would you lead the hoses? A fair bit of grp work involved!

    location for holding tank for reply

    I was kinda curious because I've got the old water tank
    in front which isn't connected to the sink. The former owner
    or the one before him connected two flexible water tanks in
    back. I was thinking in the v-berth and get rid of the old tank
    I liked commanderpete's picture of the holding tank on the
    starboard side. I was just wondering like mrgnstrn is it 5
    gallons and who makes it. Any advice on which head or
    porta potti to go with?

    The small Sea/Land portable toilet sold by West Marine fits perfectly in the Ariel's marine head location. Comes with ss brackets for locking it to the sole.

    I don't have the specs on the holding tank on my boat. The system had been installed before I bought the boat. I'll try and get some measurements. Its a standard rectangular shape.

    Although a marine head/holding tank is nice to have, I have to go along with the porta-potty crowd. Unless you have a special need or desire for a holding tank, the benefits don't seem to warrant the trouble of installing the system.

    Locating the pumpout hoses is one issue. If they are installed like mine, the V-berth cushion will no longer fit. The previous owner of my boat had new cushions made that were shaped to go around the hoses.

    Its the Todd 5-gallon tank. You might think about running the vent and
    pumpout thru the V-berth and up into the rope locker and out. No visible hoses.
    What seems to me the biggest problem is where you can mount the vented loop
    so that it can perform its mighty task. Also don't confuse the Porta-Pottie capacity
    with holding tank capacity. A PP. contains pure septic, the holding tank and marine head
    set up requires alot of water to pump the solids through. I have a marine head for sale,
    a complete system-head,Y-valve,holding tank, vented loop, discharge pump, hoses, clamps etc.
    Make an offer. My Sanipottie MSD 3 1/2 gallon is not for sale.

    As for the water tank I allways wanted one and I finally found a stainless one that fits
    perfectly in the v-berth. This is definately the place for additional weight. The tank
    is a little rough , some welding and inspection ports needed, so I'm thinking about a
    Vetus flexible V-tank, about 15 gallons for the foreward space, instead. Cant wait to
    pull the 20 gal tank out from under the cockpit. The question is how are these flexible
    tanks vented? Maybe you can just leave the fill cracked, well above the tank. Anyone
    have thoughts on flexible tanks in this application?
    Cheers, B.

    I took some approximate measurements of my tank, shown below.

    Its smaller at the bottom, to account for the curve of the hull. Its a real tight fit. A little more narrow at the bottom would fit better.

    I'm sure its larger than a 5 gallon tank, since the Todd 6 gallon is 8" H x 12" W x 16" L
