You might check on isolation valves. It sounds like turning off the main SP would also disable the partial one. Would the AHJ be ok with that?
Matt From: Sprinklerforum <[email protected]> On Behalf Of Jerry Van Kolken Sent: Monday, April 30, 2018 5:04 PM To: [email protected] Subject: Secondary Standpipe on Upper Levels I have a 12 story project with a partial stairwell on the top 3 floors. The AHJ is requiring a standpipe at this partial stairwell. My question is to I need to run another vertical feed from the pump on the first floor, or can I do a horizontal feed off the standpipe in the opposite stairwell on the upper level?
