Darkroom ductwork/ventilation/plumbing

How high are the ceilings?

Here is a picture of the plumbing. I'm still not sure if I can use the vertical white pipe as my sink drain. From what I've read, using a vent as a drain can be done (it's called a wet vent) but only under certain circumstances with good results.

If you google 'wet vent' you will see diagrams of how to tie a a drain line into vent. The access looks really tight to use the water lines for the tub.

I bring my water into and out of my darkroom with large kitty litter pails. Also have a water cooler / heater I use when I need a good supply. Been thinking about plumbing a bottle for it so it's a constant supply. But the more I use, the more I have to bring out. Toyed with the idea of using a water pump to bring it out of my darkroom, but not really worth the effort.

Hi Wayne,
My darkroom is separated from any water services by a corridor. Since it is basement my choice was working in concrete floor, water in/out by hand, or pump. Bringing water by copper pipes is not a problem, for water out I have installed pump. Pipe (1 1/4") goes over ceiling to laundry room, I did not bother connecting outfall to sewer pipe, my pipe empties simply to laundry room sink. It works like a charm, I stopped even noticing water running from time to time. Cost is not great, pump around $100, garbage container (must be with relatively flat bottom), and time for gluing pipes.

I did a little writeup of how the plumbing project went. I'm now building my darkroom sink. Next priority is ductwork and venting followed by electric.
