Just because the max spacing is 16-6 doesn't mean it has to be that far
apart, with multiple row racking you may have to have them spaced at 8'-4
apart so that you don't go over the sqft requirement.
124/8.333=14'-10

I hope I am reading this wrong but here goes. We are using NFPA #13 (2022ed)
section 23.4.
We have a client that said they would be storing exposed expanded group A
plastics on racking and we advised about the requirement for vertical barriers.
They now supply us with the racking drawing and th
As well as water supply, size of combined test connection, all for simultaneous
operation.

NFPA 25 add
If these are electric pumps, power to the pumps must be sufficient such that
both can operate as anticipated.
Also, NFPA 20 has required the following for fire pump field acceptance flow
testing since 2010:
Where simultaneous operation of multiple pumps is possible or
required
NFPA 25 added a section regarding this in 2023.
8.3.3.11: Where simultaneous operation of multiple pumps is required to meet
the water-based system demand for flow and pressure, the requirements of
8.3.3.10(2) shall be repeated at each flow condition with all pumps operating
simultaneously.
So
I would think you would need to do both, at least initially. Individually to
find out that each pump is working correctly itself and both to verify that the
full demand can be met.
For a future testing program, probably something specialized would be needed.
Make sure it is
I have a project that requires two 1500 gpm pumps to meet the most demanding
system requirements. Client doesn’t want any pumps over 1500 gpm. Long story.
As far as testing, would you test each pump individually or together or ??
Trying to establish what we need as far as a test header.
