I have attached a photo from the owners manual of my 2005 Beneteau 323. My boat is on the cradle 1.5 hours away from where I live and life is getting in the way of my boat tasks. I am changing my 20 year old sanitation hoses. I have used this forum to gather a lot of great information. Plan to use raritan Sani/Flex hose. Changing the hose from the bottom of the holding tank to the deck pump out is no problem. My concern is the hose from the manual jabsco marine toilet/manual pump to the holding tank. The hose leaves the head and enters a wall and I thought it came out the other side in the starboard locker where the holding tank sits. I realize now it probably doesn't. I think it goes to this three way valve, photo enclosed. I do not have a macerator. I really forgot about this valve. It is under the sink in the head/shower area. It has been sealed with a red zip tie( use to sail out of Chicago and they required inspection each season). They required this so people would not discharge waste into Lake Michigan. I realize now that the hose from my toilet to holding tank is probably in two sections. I think I need to run a section of hose to this valve from the head and then a section of hose from this valve to the holding tank. I am posting this and asking if anyone with a similar setup has done this or specifically if anyone with the same 323 has done this. The owners manual is relatively scarce on details. I can't get to my boat for a few days and am wondering if I am on the right track.

Hi Mike.
Your 2005 boat is young enough for me to assume it follows the standard way of plumbing. The hose from the toilet generally runs directly to the top of your holding tank. This is not to believe that the installation followed the standard recommendations. You still need to inspect you boat to verify how it was plumbed.
That Y valve is most often used to direct the outflow from the holding tank. Effluent flows from the bottom of the tank to the Y valve. From the Y valve, one direction goes up to your pump-out port. The second flows from the Y valve to a discharge 1.5-inch diameter through the hull (often through a pump) exiting under the boat. The pump sucks and pushes the effluent out of the boat, the vacuum hose on the dock sucks the effluent directly out the pump out port from the tank.
It is a 20-year-old boat, and others may have altered the plumbing or connected it at the boat's commissioning in a way that meets local thinking, but I suspect not.

Thanks for your reply. My holding tank has on the bottom one barbed outlet and the hose going from it goes to the deck pump out, pretty simple straight forward. No other outlets from the bottom of the tank. The top of the tank has a vent of course and also one hose that brings in the waste from the head. Much of the hose that goes from the head to the top of the holding tank is hidden in the wall(that really can't be accessed). I tried to estimate the amount of hose I would need for the run from the head to the top of the holding tank but is difficult due to it being in the wall. So I thought I would run a snake through it and measure the amount of snake to estimate the footage. I tried to snake it from either side, the head side and the tank side. Both times the snake hit an obstruction. I think it is the Y valve. I think the waste from the head goes through this valve and up to the top of the holding tank. It is in that position now. The valve could be switched so that the waste would be discharged overboard but is tied(locked) so it cannot be discharged overboard. I am the original owner of the boat and this is the way it came from the manufacture. I will get to my boat in a few days and closely exam the plumbing. I will update the post after I have stuck my head in the cabinet under the sink and closely exam what is hooked up to this valve. I have attached more pictures of the valve.

Mike, I think that our boats are probably plumbed similarly; (2006, 343, without a macerator pump, sold in Chicago). According to the schematic in my owner’s manual, the hose from the toilet output is connected to the bottom port of the Y valve. The hose from the forward port on the valve runs to the top of the holding tank. The hose on the aft port on the valve is connected to the overboard discharge thru hull fitting. So with the Y valve closed (top of handle, without lockout hole, in forward position) waste is directed thru Y valve into the holding tank. With the Y valve in open position (handle in aft position) waste goes directly overboard. The last hose connects to the bottom of the tank & runs to the deck pump out port. You can’t empty the tank without a macerator or of course using shoreside pump out facility.

Hey John, you know that the French are a bit unconventional in their thinking; thus “non standard” plumbing!
You're replacing all the hoses, which will get rid of whatever any obstruction in the toilet discharge line might be and allow you use a single piece of hose..And since it's now an uphill run to the inlet on the tank, I recommend that you re-route it to go up from the toilet just high enough to create a loop in it--not a vented loop, just a loop--that's a few inches above the top of the tank...gravity will get it the rest of the way, allowing you to flush directly into the top of the tank. From the description of the "wall" the toilet discharge line has to go through to get to the tank, this will require cutting a new hole in the wall above the top of the tank. The advantage to doing it this way: You only have to flush long enough to move the bowl contents over the top of the loop, which conserves holding tank space because you'll be using a lot less flush water. And because SaniFlex is so flexible, it will be an easy job.
That's my $.02 worth...your mileage may vary.

Mike,
One final thought (that you probably don't want to hear)! If you're going through all the effort of changing hoses, you might want to replace the thru hull fittings, ball valve, & tailpieces in the head. That was another project I have been working on over time. Changed out the galley & head fittings & hoses, in July, using Groco bronze with BSPP threads to eliminate problem of incompatible threads and Beneteau inferior bronze / brass fittings that are present on all of the plumbing fittings.

I replaced the sanitation hoses today. It was set up initially so you could discharge into holding tank or into the water. The Y valve is a diverter( that is what I call it). On my boat the hose to discharge into the water went to a through hull that has been sealed since I purchased the boat( I am original owner, manufactured installed). We only discharge into holding tank ( we sail Lake Michigan). I am posting this to say thank you to Peggy Hall. I read her posts and books. Great advice, especially the Raritan saniflex hose. It was easy to cut cleanly. It is more flexible than other brands, makes installing much easier ! Great advice.
Thanks for the kind words! It's always nice to hear from someone who finds my advice useful! And thanks for buying my book!
