I saw suggestions but no response- What exactly is the ITM guy to do with the storz connection? Pitot?
I guess they didn't read the part of the handbook where the FDC is a supplement, not a replacement supply- 3- 5" storz to a 12" header? Does the responding FD have enough oomph to pump in with this much? Is there a massive hydrant bank or alternative outlet on the tank for the FD to take suction from, or something large to draft from? glc -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Splawn, Shannon Sent: Monday, November 02, 2009 1:20 PM To: [email protected] Subject: RE: Test header at pump house Each storz has a 6" butterfly control valve. The plan also includes a flow meter that is returned to the storage tank. As I said, this is just me copying the design done by another for this customer and I've learned not to question a lot of what was done beforehand...

Is there a valve you could use to control the flow from each connection? (How to balance the flows if not?) Wouldn't a flow meter be cheaper than 3 Storz and hose monsters?

I had to add the FDC to my plans because it did have one on the "original" The test header has (3) 5" storz connections on a 12" manifold and 12" pipe from two fire pumps.

It's a case where I am duplicating an existing fire pump house to a brand new site in another state and the existing one is set-up like I described. I just am not 100% comfortable with the way it was done but at the same time I am not 100% certain that it was "wrong" per NFPA 20 or Factory Mutual.
