I'm moving my washing machine into the basement.

What is the minimum distance that the standpipe should rise above the trap?

I just dry-fitted the parts, but am concerned that I only seem to have
about 12" of standpipe above the riser.

Thanks.

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.

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.
