In our area they don’t make us perform the test but we are required to have a sign at the fdc with the flow and pressure needed to get the 100 psi at the remote hose conecttion.

One of my colleagues just invested in a used fire truck figuring the best course of action is to be over prepared than under. Another company gives “donations” to the local Fire Dept. to come and flow the standpipe at test time (this can get expensive over time). But we always provide a hydraulic calculation for the required flow beforehand. I found most Fire Pump operators start with 90-100 psi and increase by 10 psi until we reach the desired flow and pressure on the roof.

I only did it once but the firemen seemed excited to do it. I have been required to run some quick calculations to tell them what pressure the pumper needed to provide at the FDC to give them the pressure they wanted at the top of a standpipe pretty much every one we do.

I have been told; A. You don’t have to flow test. B. Perform flow test and calculate assistance needed. C. You need to do a proper test with a pumper truck. The only thing I can find in 25 is that no hydrostatic test is required on manual wet. Can anybody steer me in the right direction?
