** A laundry tray waste line is permitted to connect into a standpipe for the automatic clothes washer drain. Can you please explain this? **
I think they are talking about a laundry tub or sink which appears to be able to be connected into the same line as a stand pipe for a washer.
Just a guess though as I have no plumbing qualifications.
