So with the by-pass and valve any concerns if the FDC is taken off a remote part of the system vs. the header? Different being flowing 700 gpm through the system (grid) vs. only through the header. Just thinking if something goes wrong. Yeah, I'd like to know before the fire but the building owner is probably just pissed I wet everything.

I have heard people say just flip the check valve, but then have many fitters tell me to get my butt out there and flip the check valve. It is not quite as easy as it sounds.
