I want to move the location for the washer hookup in an older house. At the previous location it was a one and a half inch drain and it worked 'okay'.... I am looking at one and a half inch at the new location but with the drain sneaking around a floor joist. I have attached a picture of the configuration I was thinking of. What are the chances this is going to be a disaster? Maybe I could put a flow restrictor on the washing machine?
