Please review Catt Hall PRV installation. Need sizing for new Fisher valves plus ideas for proper safety venting for the current Armstrong installation.

I've been talking to the LAS administration and we would like to get new signs for the Men's and Women's restrooms on the basement floor of Catt Hall. The signs are currently for Men and Women, but we'd like to have them changed to Gender Neutral signage for inclusivity, since they are each just a single stalltoilet with a lock already in place on the door. I'm not sure the exact process required for this, but I thought I'd try here first.
