Hopefully some of you can give me some guidance...
I am hoping to add a laundry sink to my utility/laundry room. Initially, I was going to "T" into my washer drain stack, but was told that isn't possible because of the siphoning of the p-trap and back-flow into the sink. Makes sense now.
So I moved onto the other drain in the room. This drain (see attached picture) was used to drain my AC condensate. There was no visible trap... just an open pipe up through the floor. Then, a couple of years ago we installed a 92% efficiency furnace. They ran a furnace condensate line to the same drain and installed the trap above the floor. Again, see the picture for the current setup. I would like to use this drain for the laundry sink, but would like to continue to use it as a gravity-drain for the furnace and AC condensate. Is this at all possible? Is my only choice to go with a condensate pump and send that waste water elsewhere? Could I wye in under the sink p-trap and delete the trap that is there? Any other thoughts? If the damn furnace condensate line wasn't so low, I would just run it into the sink itself.
Another question... is it possible that there was never a trap installed under the cement for this line? When it was just an open pipe with the AC condensation hose dripping in, we never smelled sewer gas.
Thanks for any thoughts you can throw my way! Very appreciated!
