After finally reconstructing and refitting the darkroom with all the equipment I set one night to try it out. I called my cousin who has some films for development and he came to test the new Jobo. During the development I smelled something bad. Pretty bad. "You farted" I accused him. "No, I did not" he denied the accusation. "You are not supposed to fart inside a darkroom you know", I insisted. "I did not fart!", he exclaimed. I smelled more carefully. "Yes, it does smell too shitty to be just a fart". It thought a bit. Then it came to me. You see, there used to be a functioning toilet seat in the room which was removed during the reconstruction. But the pipe remained and I thought I could use it for water drainage. Unfortunately it seems to be pretty connected to the sewage system and it carries all the aromas of mother nature in it, especially when someone in the appartment building uses it. I have called the plumber and meanwhile I have left the door open. I am sure all your chemicals, not even sepia smells that bad! How about that for a photographic related toilet humor?
