Oops sorry! I spent too long sitting at my screen before submitting my comment. Didn't see comment before me until I updated.
This only applies to professional plumbers and people taking out permits and getting approvals.
He certainly wouldn't be making it more hazardous, unsafe, insanitary or overloaded beyond what the original code that allowed it did.
Well I suppose one problem would be it wouldn't meet code as it applies to "Alterations to existing".
But it likely would not comply with either the older or newer codes, if you make the visible piping larger than the downstream piping.
BTW...What is that 2" pipe used for currently. Drain and vent for your existing washer?
Ontario Canada plumbing code in 2000 did not allow a 2'' drain to the washing machine
so the 1 1/2'' piping has never been legal or approved for a washing machine.
I had a flashback and recalled that this area had a basement bathroom rough-in. I remember a 3 or 4" pipe in the slab that would accept a toilet so I have to (want to?) believe that the 1 1/2" stub has to be joined to that before going to the stack. I definitely will or have someone check to make sure.
He is tied into [most likely] the old tub drain
Take a 16 pound sledge and bust a hole in the floor close to the pipe
dig it up and LOOK
