I’m not sure if this is the right area but I figured it would be as good as any of the other area. So here is my situation. I recently bought a house that needs a lot of remodeling work. There was a leak in the laundry room that was causing slight mold and damage to the drywall. When I took the wall off, I could see that the old gate valves have been leaking and caused the damage. I bought a replacement unit that has quarter turn ball valves and a 2″ PVC drainage pipe outlet.
I’m not worried about having to solder the copper pipes but I’m not sure how to deal with the drainage. The existing pipe is copper with a trap that connects to a cast iron elbow vent/drain. My new washing machine box has a 2″ PVC drainage outlet. So what would my best option be: Use a fernco fitting between from PVC to copper? Remove the copper and re-plumb into cast-iron tee with PVC? Or any other options?
I’ve attached a picture for reference. Thanks!
