This seems to be the year for blocked heads. our 36i badly blocked as our friends moody 386 and bavaria 33,so jeanneaus are not the only boats giving trouble.would it be hard to fit a bypass valve to avoid going through the tank,only to be emptied at sea of course.I would like to hear from anybody who has solved this problem,and maybe show some photos. nac.

You need the y-valve yes, but I don't see why you need a 2nd skin fitting, the y-valve sends it out or to the tank. On the other hand could be something in the diet, or too much toilet paper of the wrong type, which does not break down easily, too little flushing, remember it takes 7 full pump's per meter to clear the 1 1/2" hose from toilet to tank as per Jabsco instructions, too often people "hold" back as they don't want to fill the holding tank with water, flush away sailor, I don't know how much the electrics one's pump thru, would you need a double flush for a big job ??

You WILL need another skin fitting. Currently you have a system that allows you to turn off the holding tank skin fitting and fill the holding tank or empty the holding tank. i.e. not use it. Fitting a Y valve will give you an additional outlet from the heads, one way to the hoding tank, the other way to: well, I suppose you could let it go into the bilge but its not my choice!! I would pipe it to another skin fitting. This means you know a choice of to store or not to store the output from the heads depending on where you are.

Could just be me, as I don't like drilling hole's in the boat specially not below the waterline. What if the 1 1/2" hose from the toilet goes to the y-valve, one side of the y-valve goes to the tank the other to the seacock. At the seacock you fit a T-piece with a ball valve on either side, that way the tank and y-valve will have it's own connection and valve to stop any back flow so you close / divert 2 tank valve's and it all go out to sea, or close seacock and divert the y-valve and it all goes in the tank ?? Close - open - divert you will need to be a Master of valve's This all started from blocked toilet, question is where does it block, at the seacock ? Suppose nobody really knows, back to the flushing in the first place, the diet, the paper, did something else get put in there. Man I'm glad I just changed my hose's last weekend, so no blocked loo here and the little "smell" from time to time has gone, it was the hose from tank to seacock which had the pleasant smell. Unpleasant job and at time's difficult, specially getting the hose's around corners both old and new, so Nac if it's not your cup of tea then get the plumber to look at it, he will also have all the bits needed.

I just drew a sketch to see how this works - I know I would be keeping well clear of being anywhere near those heads when the tank valve is turned, my shoes have enough polish

Some may say it's just pooh under the bridge or in this case the tank or the sea. I looked at this some time back, drew a sketch and I couldn't see why it should not work, again avoiding big holes below the waterline, main problem was having to train 3 women crew in the open-close-divert skill's....too hard basket, better pumping process was introduced, so fare so good.

flight deck,
This sounds like the setup I did. 2 Y valves, have them one way, out to see, turn the first the other way, and into the holding tank it flows.
It should be pointed out, "IF" you have a Y valve in the states, where you can go to the tank, or out of the hull, when with in "5? miles" of land, you are supposed to have the Y valve hose clamped so one can not just turn the valve from thru hull to tank if boarded for an inspection.......not that I have done that......but per the local coast guard aux inspection, I am supposed to have said hose clamp!

If the boat has been used for a season or two then it is not unexpected for the pipes to reduce in diameter due to the build up of 'cake' as a friend of mine calls it. Some people take the pipes off and whack them on the ground to get rid of this build up. A simpler solution is vinegar. Just pour some down the loo and pump it through the pipes and into the holding tank too. Do this on a regular basis. Hope this helps. Admiral

Admiral Indeed Admiral , a couple of months ago I had to disassemble both Y valves (i have two toilets you see) and found out that the tubes diameter was reduced by atleast 1/3 . I wouldn't call it cake , it looked more like cement. Anyway , the vinigar is a solution , but it will harden the rubber parts though.
