Are you allowed to have a valve off the standpipe feeding a hose valve that is not in the stairwell?
Working in a high rise building with two stairwells. It is dual fed with combination riser standpipes. On the tenant space there is a hose valve and they want a butterfly on the feed for the hose valve, always thought that was not allowed but couldn’t find it. Thanks in advance.

Yes, allowed and it's required when the single hose valve is greater than 40' along a branch line (14-22' - 6.3.3). Minimum sizing & hydraulics per 14-22' 7.8 & 7.10

Yes, you can valve off a hose valve. Reminder to install a tamper switch on this valve.

Yep. The valve will need to be supervised though.

Yes, this is allowed contingent the valve is supervised.
