Subject: Re: Standpipes
Doesn't NFPA 14 require standpipe isolation valves? How can you individually
isolate the standpipes in the scenario you describe. The valve that controls #1
would also control #2&3. That doesn't seem to correlate with a requirement to
be able to individually isolate each standpipe.
