The test layout shall be drained and the defective hose removed from the test layout. The service test shall be restarted beginning with the above procedures. After the 3 minutes at the service test pressure, each test cap shall be opened slowly to drain the test layout.
In North America, a standpipe is a type of rigid water piping which is built into multi-story buildings in a vertical position or bridges in a horizontal position, to which fire hoses can be connected, allowing manual application of water to the fire. Within the context of a building or bridge, a standpipe serves the same purpose as a fire hydrant.
Returns were taken out of the standpipe at the end of the PVC model and fiber cement … This was a repeat of Test 2 but using the inline mixing method similar to Test 1 … The model is open to the atmosphere and the system pressure after the choke should be near … During the pumping, the gauge near the relief valve never read over 10 psi.
Standpipe definition, a vertical pipe or tower into which water is pumped to obtain a required head. See more.
The large-flow injection phase continues until the water level in the accumulator tank falls below the inlet level of the standpipe, and the flow in the standpipe almost comes to a stop. The flow from the small-flow pipe enters the vortex chamber tangentially, which creates a strong vortex in the vortex chamber.
Flow Test—to verify that the water supply still provides the design pressure at the required flow. Fire Department Connection—back-flushed at full flow. Contact A-Total Fire Protection to schedule your wet/dry standpipe fire safety services!

The minimum pressure while flowing the required standpipe flow (500 gpm from the hydraulically most remote standpipe and 250 gpm from each additional standpipe, up to a maximum of 1000 gpm for a fully sprinklered building) shall be 75 psi at any valve outlet while flowing 250 gpm through each valve.
