Immediately after turning gas into the piping, the system shall be checked to ascertain that no gas is escaping. This can be done by carefully watching the test dial of the meter to determine whether or not gas is passing through the meter. To assist in observing any movement of the test hand, wet a small piece of paper and paste its edge directly over the centerline of the hand as soon as the gas is turned on. Allow five minutes for a one-half foot dial and proportionately longer for a larger dial in checking for gas flow. This observation should be made with the test hand on the "upstroke." If careful observation of the test hand for a sufficient length of time reveals no movement, the pipe shall be purged and the small gas burner turned on and lighted and the hand of the test dial again observed. If the dial hand now moves, it will show that the meter is operating properly. If the test hand does not move or register the flow of gas through the meter to the small burner, it is certain that the meter is defective and the gas should be turned off and the gas company notified. If the test hand shows movement, ail appliances or outlets supplied through the meter shall be examined to see if they are turned off and do not leak. If they are found tight, movement of the test hand will indicate that there is a leak in the piping system. The meter valve shall be turned off until the necessary repairs have been made, after which the test specified in this section shall be repeated.
