Todd:
I hate to pick nits here, but that’s a very selfish request. Why didn’t you
ask to have the test video-recorded so we ALL can watch?
For the good of the order, of course.

The intent of the ITC is to simulate the flow of one sprinkler in order to test
the alarm activation. The fire pump has nothing to do with it. There is no
measuring the flow from it. However, if you colleague is going to pitot an ITC,
call me. I want to watch.

I have a colleague that says must use fire pump rated pressure to determine
flow from inspector’s test connection. I said its a restricted orifice to
represent a sprinkler head flowing. Therefore pump pressure is negligible. Who
is right?
