Re: Jeanneau Attalia
That's what I thought. But the y valve ( on the aft side of the head wall) seems to have some other function. I think it might link up with the manual bilge pump (also on the aft wall). One of the hoses for example ends up in the lowest part of the floor in the head, underneath the floorboard. This y valve can't be linked to the head or the holding tank.
The discharge hose from the Jabsco head seems to go straight out through the aft wall in the head and does not come back.
Oddly, I have the original owners manual and there is not a single diagram that describes any of this.
Now based in Barbados.... and wait for it.....the boat is too!
