Aft head intake pipe

[John R M]

Our new to us 1985 38' OA Double Cabin is giving us issues with the aft head in that it won't draw in water. It worked for about a week but now it doesn't. I can't find where the intake pipe goes through the hull or if there may be a filter that is clogged. I can see where the supply hoses for the head sink go through the back wall of the engine room and where the drain hose enters the engine room, but there is no sign of the supply pipe. Can anyone offer any advice?

Probably have to find a way to trace the hose. With these older boats it can be a challenge sometimes.
