I am adding a laundry room and need to move my washer and dryer. The move will be apx. 4' along the same wall. The drain transitions from cast to pvc with a trap under the slab. My question is - do I need to move the trap or just 90 over to the new location? My house was build in '76 so I'm sure things are done differently today - if I need to add a vent etc. please advise.
