I am in the process of moving my laundry room from the main floor to the second floor off the master bedroom. I have already relocated the washer and plumbed in the new supply and drain. Unfortunately I could not access the stack from this location and only have access to the 1.5" drain line. It wasn't much of a surprise to me that upon running the first full load of laundry that water backed-up in the kitchen sink downstains while the washer drained. Due to the design of the house it is not feasible to access the stack.
The drain lines are fully clear. When the water backs up in the kitchen sink there is only 3 gallons at max. My question is would a drain check valve under the kitchen sink safely prevent this back-up (and if so where can you get a check valve for 1.5" abs). I am assuming at this point that the amount of water backing-up in the kitchen sink can be contained in the piping up to the second floor washer. I realize that it may indeed causing an overflow at the washer.
I have already considered the option of installing a laundry sink but I am very limited on space and even a space saver 18" wide sink is a bit much.
Any advise is appreciated greatly.
