How are three hydrant flow tests conducted? 1

[AncoraImparo]

Hello all,
What is the procedure for a three hydrant and two hydrant flow test?

Thank you for your help.

While there are slight variations in procedures involving multiple hydrants, the general process is basically the same.

The hydrant closest to the projected point of demand is used for the residual hydrant. The flow hydrant is selected to allow for water to flow past the residual hydrant. The residual hydrant is on the same main as the flow hydrant as well as between the flow hydrant and main source of water. The residual hydrant is on either side of the hydrant on balanced grids. When multiple hydrants are tested on a grid, the residual hydrant is located between the flow hydrants
