Plumbing setup just doesn't seem right
Here's a drawing of my plumbing setup in my 1975 Capital Yachts Newport 28. I haven't ever found an actual manual drawing that matches this setup, so I'm thinking a PO must have done some mods to it. I've left out some details to make my (poor) draftsmanship more legible.
The only actual drawing from a Newport owner's manual that comes close has the waste and freshwater inputs reversed from what my boat has. That makes eminently more sense, as you don't pump out waste through your v-berth as my setup currently requires.
The fresh water input connection on my boat is completely unseeable by human eyes. I was able to get my hand on it, but that's all. I don't know how I'd ever replace the fittings if they needed replacing -- maybe by touch.
However, the input line is accessable via an inspection hatch at the forward part of the v-berth. I'm thinking I could cut the line there, reroute the freshwater input over to where the pump-out fitting is (replacing all fittings, natch) and run the current freshwater line over to the holding bladder and make that the pump-out line.
Hopefully the attached drawings will make this clear. Does it seem like a plausible refit?
