I would definitely be adding the sink, not replacing the washing machine. So Gary's response of the adapter tee makes sense, I just wasn't sure if the new plumbing from sink could be PVC if the adapter is steel. Thanks for the assistance.
I would like to install a laundry room sink using the current washing machine drain. The drain is 2" steel pipe and I'm wondering if I can connect into it using PVC pipe, essentially connecting a piece of PVC to steel. Please advise.
