We're looking to remodel a fairly large closet (15'x6') on the second story to be a laundry room.
The previous owner was going to make a dark room to develop photos out of this closet meaning a sink of some sort. They took the first step in this and ran 2" PVC up through the wall to a sanitary T (about a foot above floor level) that reduces to 1.5" that runs about 30" to the left before being stubbed out and 1.5" straight up through the roof to vent.
So converting the 30" run to the left into 2" and adding a trap is not difficult.
The part I have the question about is since this is on the second story, we definitely need a way to catch overflow, etc. I've never cared much for the little catch pans that do little more than catch overflow, so I was looking at doing a full floor drain instead. Sloping the floor toward the drain and the water proof barrier and tile on top of that is easy enough. The question I have is about plumbing the floor drain.
Now since we'd have a full on capable floor drain with all the tile/mortar bed work, I would prefer to plumb the floor drain into my septic system rather than just run it down and dump it outside the house for emergency use only.
If I just insert another sanitary T in the stack (below floor level) and run it out into the middle of the space a couple feet, I'm concerned that the washer dumping in above where the floor drain would hook into the stack would cause water to flow up out of the floor drain.
I'm also concerned about the floor drain not being used a lot and the trap drying out, so I'm wondering how to best deal with this.
It seems I could run a second 2" PVC line down through the wall through the first floor into my crawl space and hook in there to prevent the backup, but its a fair amount of extra work and does not solve the dry trap issue. What options do I have here?
