I'm looking to replace an old recirculating toilet on my 1978 Hunter 33. I would like to mount a holding tank under the cockpit in the space behind the rear quarter berth, there is a fair amount of wasted space in this area and the weight would help offset the weight of the stuff in the cockpit locker. I could probably mount a 15 gal poly tank in the available space but I'm concerned about two things. First, the tank would be about 2 to 3 higher than the base of the head. Is this a problem? Second, will the sloshing of waste in the tank be annoying to someone in the quarter berth. This is my favorite berth on board. I've had a couple of people suggest using a flexible tank. Does anyone have experience with these? Is smell an issue? (that's why I want to replace the recirculating head in the first place). It looks like I could fit a 25 gal or larger flexible tank. It would still be mounted higher than the head oulet.

Flex tanks
Check the Head Mistress Archives for flexible tanks and you'll find LOTS of conversations about them - mostly negative. LaDonna

You don't want a flexible holding tank!
"First, the tank would be about 2 to 3 higher than the base of the head. Is this a problem?" Unless you mean feet, this is not a problem. "will the sloshing of waste in the tank be annoying to someone in the quarter berth." Nope...they shouldn't even hear it. Mine was under my v-berth...I never did. Ronco Plastics (link below) makes top quality rigid plastic tanks and has more than 400 shapes and sizes to choose from, including more than 100 that are non-rectangular. You should be able to find one that will fit your space.

replaced mine with a rigid
Bob, Several of us with the older 33s replaced our tanks with rigid tanks. I put a 20 gal tank strapped up to the underside of the side deck in the starboard lazerette, aprox 18" aft of the bulkhead the flex tank was mounted to. There are pictures of someone elses installation here in the archives. If you can't find them, let me know and I'll send over a few shots of mine (1977 H-33). I made a mistake not following Peggys advise. Waste laying in hoses will cause oders in a relatively short time (1.5 years). These hoses are expensive and nasty to replace. Better to have a stand pipe in the tank and all hose connections on the top of the tank...safer too.

Thanks
Thanks for the quick response. I actually did mean 2-3 ft. That's assuming that the discharge hose comes out of the bottom of the toilet and goes into the top of the tank. The total length of hose between the toilet and tank would be about ten feet with a couple of 45 deg bends. This whole refit scares the crap out of me (no pun intended). I'm afraid that I will end up with a system that smells worse than the one I'm trying to replace.

Lot of hose Bob.
Is there not a better location for the tank? I installed my new system(H37C) so that it is about two feet to the top of the vented-loop from the base of the head. A little uphill, then mostly downhill to the top of the tank. Installing Sealand hose was a trip, no flex and no fit without considerable heat. The other vented-loop in the picture is the inlet.
