Ed, Here in Vegas we do things that may not be done elsewhere. The International Building Code requires a minimum headroom be maintained throughout the stair and landing. The minimum headroom is 80 inches. If you keep the control valve above this height (allowing that you have the space needed) keeps you out of trouble with clear widths and projections into the exit path. If you don't have the space needed, we have been moving forward with the floor control valve in the vestibule and the hose connection in the stairwell. The vestibule is required to have 44 inches of clear width so we have been recommending the clear width be provided between the supply piping and opposite wall. This way you meet both the headroom and clear width requirements for exiting.

Any recommendations from owners or AHJs? Any horror stories due to them being too high or too low?
