not be enforceable.
Section 4.20.1.4 indicates that the test header is to be installed “…on an
exterior wall or in another location outside the pump room…”
Since this valve must be a listed indicating valve per Section 4.20.3.3.1, I
believe the intent is similar to that of the pump controller
I have a pump room where an esteemed colleague suggested I locate the fire pump
test header control valve near the test header on the vertical pipe to limit
the amount of “dry” pipe. Since the valve would be located near the top of
vertical pipe the dry portion of the pipe would drain well and
“backwards” or a test
header arrangement.

Why do you need to demonstrate the flow rate? The purpose of the forward
flow test is to fully operate the back flow valve. A flow at 500 GPM will
not open the valve fully?

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

Not exactly, you modulate your flow with the test header valve. Those
individual valves in the header should be just to open another stream, full
open or full closed. You never want to expose the downstream side of the test
header valve to full system pressure when it's normally empt
No it does not change it. Your concern is with testing the pump at
churn, 50, 100, and 150 rated. You use the test header control valve to
control the flow, the control valve serves the same purpose as the
individual hose valves.

I'm doing a 13R system that is requiring a 70gpm @ 50 psi pump. All of the
pumps I'm pricing are assemblies w/check valves, control valves, flow
switches, etc. w/ no outlet between the check and discharge control valve
for a test header. 13R says the pump is to be per NFPA20. Unless I
