Hi Tom
Thanks for your answer.
I was familiar with these aspects and this confirm it.
I wanted to make sure that an existing standpipe system dated of 1976 in a
condo building of 21 floors was able to withstand the new fire pump
requirements at churn. The standpipe seems to be made entirely of welded joints
(with a min. of schedule 10 piping I assume). In this case, I guess, only the
hose connections will have to be replaced by pressure reducing valves.
