Drain Standpipe lengths
Drain Standpipe lengths
(OP)
I looked, honest I did. Somewhere in 13 there's a table or paragraph specifying the length and size of drain pipe standpipes or risers. I have a mechanical drawing where they are proposing to put a 6x3 reducer on a 6" piece of 3" on a p-trap for the 2" main drain. Doesn't seem near long enough to me.

With ~6+" of piping above the p-trap, you will get a little head pressure, but that will not likely be enough to flow the drainage from a test on a main drain.
Sounds like a recipe for floor puddles.
RE: Drain Standpipe lengths
is the question how close should the pipe be to the drain??
or how big of drain pipe off the system should it be??
I agree draining into a floor drain does not work
