Hi folks, We are in the process of installing a new head / toilet (manual) in an Albin Ballad 30', the holding tank is above the toilet and the sliding sink is in between. The boat is in Florida and I am in Canada working (to pay for it

).
The folks installing the seat are not sure how to route the plumbing and suggested eliminating the sink (which I turned down). Is there anyone out there that has a diagram for this layout? ideally, I would like to know if the tank above the toilet is stock/original, this one is a stainless steel, and if anyone can post pictures if they do have the same set up in an albin.
Thanks in advance. Cheers, Edgard
