5-Year Standpipe Flow Test

[@iowafire8416]

For a 5- year full flow test on a standpipe you need to achieve 500gpm at the most remote hose valve, then you must flow every standpipe until you reach the capacity of the fire pump. On systems equipped with both standpipe and sprinklers the max flow rate would be 1000gpm, for standpipe buildings only and partial sprinkled buildings you go up to 1250gpm. So from what was shown on the video and the video description, that was not a 5- year full flow test. Or a 5- year full flow test done wrong.

Danny, do you not have to hold the pitot half the distance from the face of the playpipe when you are using a playpipe? So in a 2-1/2" hydrant you should keep the pitot half the opening away from the face of the 2-1/2" hydrant nozzle which would be 1-1/2".

Dont see standpipe test headers often..

What year is this? Why are you using a pitot tube and not a hose monster?

[@cmarname]

How do you measure the flow? I understand that the pitot tube only measures pressure?

[@ChesterPolesky]

There's a chart that goes along with pitot tube that gives gps

Just curious, was ILSM necessary with this noted deficiency and the issue with fire pump?

[@asheaha]

Tim - Great question! Yes an ILSM assessment was necessary and we did implement a few ILSM's, including notifying the fire department of the current pressures and what they are suppose to e so they know to hook up to the FDC if additional pressure is needed.

Shouldn't it be 100 psi for a 2.5" hose valve at 500 gpm? 🤔

[@MrLhill1222]

@@jobi013 Depending on what year the building was built .

@@jobi013 I understand that some old systems are designed for 65 psi (residual pressure)

@@jobi013 For a Post 93 System. Yes. 500 GPM at the far discharge at no less then 100 PSI.
