What does the FDC pump operator need to do to ensure the appropriate amount of pressure makes it past the PRVs on the fire floor?
What does the FDC pump operator need to do to ensure the appropriate amount of pressure makes it past the PRVs on the fire floor?
- Rely on the building's internal clappers to deliver water into the building
- Increase pressure until a residual pressure drop is seen on the master intake gauge
- Ignore the flow meter portion of the gauge if it is not working
- Determine the pressure needed at the top floor and supply that pressure to the building (correct)
