No, it's right under the cushions. The freshwater tank fill is forward in the anchor well, as are the two vent lines, but the holding tank pump-out is in the v-berth. Methinks some replumbing has occurred in the past. I'll have to take more pics next time I'm over, but here's one I got of the y-valve. The yellow line on the bottom is from the bladder. The green line on the left goes to the pump-out fitting, and the one of the right goes to the through-hull via the hand pump and anti-siphon valve. None of those lines look like sanitary hose to me -- I thought that stuff was smooth.

I had assumed that during the pump-out the bladder just collapsed, or else the line from the head allowed air to flow in.

Guess not, eh?

I think the anti-siphon valve, with the y-valve open to it, was supposed to provide the venting for the bladder, since that's where the vent line appears to be connecting -- but that seems a very poor and probably illegal way of doing it.
