New kitchen sink 25' from clothes washer.
Existing clothes washer with 1 1/2" trap.
Can these two share the same 2" horizontal drain line? note there's an 8" drop from the sink line half way to the washer, so not continuously 1/4" per ft.
Will inspectors say the existing washer is not grand-fathered and therefore insist on at upgrade to 2"
Even with the upgrade, dfu's total 5, so less than the 2" pipe's 6 dfus. Was told by a pro that the sink needs a separate line all the way to the 3" stack, but I don't see that restriction in any code or online example.
