I would like to add a washing machine (and dryer) to my split-level home so that I can rent out the basement below (which already has its own washer/dryer). I don't have the experience to do it myself, but I'd like help deciding if my preferred location for the washer is feasible before seeking help.
I would like to run the drain pipe from the washer up into the ceiling of the level below, then down into the wall of the kitchen below and into the drain. Is this feasible? If so, can the p trap and venting be located as per the sketch or must they be located closer to the washer?
It would be very difficult to vent the piping near the washer as there is no existing plumbing there and there is another floor above. It is my understanding that the p trap should not be more than 5 feet from the venting, so I suspect it would not work to locate the p trap by the washer. Furthermore, doing this would increase the height the water needs to travel before dropping into the ceiling to a total of at least 60", which my research indicates is possible, but not ideal.
Can anyone confirm or deny the feasibility of the layout in my sketch and/or offer other suggestions?
UPDATE Thanks for the helpful information thus far. I understand I have two problems:
The discharge water is too high above the machine.
The vent stack is too far from the machine.
We haven't bought the washer yet so using a front loader on a 3' pedestal is a possibility. I guess this would solve problem #1. Problem #2 however, may make this setup unfeasible. The only solution to this might be venting out the exterior wall, which is adjacent to the washer. I understand that this isn't ideal but could it work if the vent stack exits through the wall at a 45 degree angle?
