I would like to replace my old washer/dryer that is currently in my basement bathroom to a storage room in the basement. The storage room is directly below the kitchen and there is a 1.5" abs drain pipe from the kitchen sink running down the cement wall. This drain pipe has a clean out/inspection connection 6" from the cement floor. Where the drain pipe goes from there is questionable and whether it remains 1.5" under the cement floor is unknown. I have had no drainage issues at with the kitchen sink nor with the old washer in the basement bathroom. So I go to local home depot to gather input into what I would need to plumb for this change. I was told by a licensed plumber that new washers discharge capacity is too great for a 1.5 pipe. What do you suggest?My home was built in '59 and I have lived here since '91.
