The confusion started when 25 said flow the most remote hose
connection. Some focused on the fact that it used the singular tense
verses plural so obviously they only had to flow from ONE outlet and
since an outlet only has to flow 250 gpm THAT was the amount to flow
for the test. DOH!

I am working with a hospital with a total of 9 standpipes. There are
standpipes that are both pre and post 1993. The original building is
partially sprinklered and the new section is fully sprinklered.
1. Is the intent of NFPA 25 that multiple standpipes be flowed
simultaneously to meet the 1250 gpm demand?
2. Should the two sections of the hospital be flow independent of
each other?
3. If yes to 1 and 2, could the new section be flowed as a fully
sprinklered building (thus 1000 gpm) as opposed to 1250?
4. How should i handle pipe schedule standpipes, if any exist?
I haven't had to deal with 5 year standpipe tests before.
