Each valve section of pipe shall be slowly filled with water and the specified test pressure shall be applied by means of a pump connected to the pipe in a manner satisfactory to the Engineer. The pump, pipe connection, gauges, and all necessary apparatus shall be furnished by the developer. Before applying the specified test pressure all air shall be expelled from the pipe. If hydrants or air reliefs are not available at high places, the necessary taps shall be made at points of highest elevation before the test is made and the plugs inserted after the test has been completed.
A leakage test shall be conducted after the pressure test has been satisfactorily completed. The duration of each leakage test shall be two hours, and during the test the main shall be subject to a pressure of 150 pounds per square inch and not permitted to fall below 145 pounds per square inch.
Leakage is defined as the quantity of water to be supplied into the newly laid pipe, or any section thereof, necessary to maintain the specified leakage test pressure after the pipe has been filled with water and the air expelled.
The maximum allowable leakage for the pipe shall be determined by the formula:
L =
NDP
___
3,700
