Fire pump test header location for fire pump located on 30th storey 1

[RyanJP]

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

All fire pump tests that I got involved were at ground level next to a body of water for obvious reasons, so now I am really curious as to the type of water supply for a pump that is roughly 300' above ground level.

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.

Need more info.

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.

Flow the water off the roof via the standpipe test connection. The connection can be in the top of the stairwell or through the wall to a valved test header. You may need to add a 2.5 inch valve to get the 750 gpm 150% rating of the pump. Install a flow meter on the pump for the 2 years NFPA 25 says you can use a flow meter.

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.

Thanks LCREP, I appreciate your help.
