"...... So while running a test with the pumps
OFF or not allowing them to be included in a calc. may be a conservative way
to do your flow test, it may not be in the best interest of the property
owner or client. (Bigger pipe sizes, larger orifices and serious overflow if
and when you do get discharge."
I always understood that it is our responsibility to provide a system
that protects a property from catastrophic fire damage. And that the
"best interest of the property owner or client" is for us to meet
that goal. If it results in bigger pipe sizes, larger orifices and
serious overflow, then so be it. We should not go overboard, but
should take varying circumstances into account that may be outside of
the strict NFPA box. Just my opinion.......
