I was afraid of that.

I was trying to leave as much of the stack uncut as possible, but didn't
think about the trap riser height.

Fortunately, I didn't install the tee yet, and am only looking at
cutting another set of holes through the studs.

Thanks.

minimum distance that the standpipe should rise above the trap?



Code Check West 2001/2002 indicates that the 2000 IRC and the 1997 UBC
require "standpipe receptor = 18in. above trap". The maximum height
is 42 in. per the 2000 IRC and 30 in. per the 1997 UBC.
