I think that the only pipe allowed in a stairwell has to be associated with the stairwell IE: standpipe or piping supplying sprinklers for the stairwell. We are on the 2015 IBC and I was flagged by the state reviewer for running a bulk pipe in the stairwell. Had to move it out into a closet.
From: Brian Harris <[email protected]> Sent: Monday, January 15, 2024 1:03 PM To: [email protected] Subject: [Sprinklerforum] Backflow In Stairwell Is there anything inherently wrong with putting the backflow & riser in a stairwell as along as all clearance requirements are met? I don't see anything in NFPA-13 and don't currently have access to the Building Code.
