Fire pump test header location for fire pump located on 30th storey
Fire pump test header location for fire pump located on 30th storey
(OP)
Hello,
I am hoping for some design assistance on a new construction project that involves a fire pump located on the 30th storey. My questions are as follows:
1) Where should the test header be located?
2) How should it be drained?
Thanks,
Ryan

High rises are way beyond my expertise, and you don't say, but I am assuming there is an atmospheric break-tank feeding this set of pumps? Could you not install a metered line back to the break tank to verify the pump flow? This would meet NFPA 20 requirements for testing for that set of pumps..
Wait for the experts here to weigh in on this one.

1. Source ( such as tank, city, another pump) and location of the water supply, next to the pump, 30 floors below, etc.
2. Size of the pump, 500 gpm, 750 gpm, etc..
3. How many stores is the building?
4. What is the pump feeding, sprinkler, standpipe?
5. If standpipe, do you have a test header on the roof?

Thanks for the responses so far. Some more information:
The source is a city main which is pumped up from ground level to the pump on the 30th floor. So two pumps in series.
The size of the pump will likely be 500 gpm.
There are 55 storeys in the building.
Pump is feeding a standpipe which is zoned per floor all the way up.

It does not matter where you flow the water to conduct the annual flow test, just as long as you can flow 150% of the pump. All pressure readings will be taken at the pump. All you need is good communications with the folks on the roof flowing water and the guys in the pump room.
