I' m planning on adding a holding tank to my aft head ..
I was wondering if anybody has a digital picture of an aft head installation on hand ??
- obviously I'm interested in the insides = how the tank is mounted and what modifications are "required" to the standard shower/head stall.

Any help is greatly appreciated

Here you go Georg. The panel adjacent to the head covers the holding tank. A one-piece molded construction. This is the original (2003) US construction.

No, it's ugly :)

The hose from the head (seen behind the head) runs to a "Y" valve under the sink - one leg goes to a thru-hull (with sea-cock) , and the other top-loads to the tank. The tank has a drop tube with hose that routes to a deck plate for vacuum extraction. There is also a vent tube at the tank top with a thru-hull vent near the toe rail.

My system got a demerit from my surveyor for not having an anti-siphon loop in the overboard discharge line. The system does not allow for dumping of the holding tank. Only direct discharge. This means there is no tank bottom leak potential.
