Issue: Submitted plans for (2) head add under a 4-0 x 15'-0 overhang in a machine shop. We submitted the plans with all the normal information. Are plans indicate we are going to install a 2.5 x 1" mech tee off of 2.5 and drop down
7'-0 x 1" to a bullhead tee then arm over 5'-0 left/right. Simple. I was told my plans are rejected because I can't supply the two heads from the 2.5 branch line because it's not permitted to pipe schedule off of a hydraulically calculated system per code.
