As an engineer who just issued a design with such a test header (COE project 
where they "suggested" we look at this provision in the design). My view is 
that the FDC is fine for project with less than 500 gpm flow requirements. If 
over that (and in my case the flow was 1100 gpm), then we need a test header so 
we can properly demonstrate the flow rate.

We installed a by-pass on the FDC line for the forward flow test, but he wants 
a test header as well.

Have not heard of this before. Perhaps he wants to do forward flow test for 
backflow preventer?

Is there any requirement to install a test header on a riser without a pump (In 
addition to arrangement for full flow FDC test)? I have an engineer insisting 
that it is. When I asked for referenced, I get the "you look it up" response. 
Just want to be sure before I scream back
