No, Eric.  On Kristy each head has its own through-hull intake in the "hall" outside each head.  The anchor wash gets its intake from the one that feeds the forward head.
In the engine room, the manifold feeds the engines, the A/C cooling pump, and the watetmaker.

Do you have a Jabsco electric toilet with the water coming from the manifold via a pump from the engine room? That is how my SM 376 is arranged.
Fair Winds,
