      (1)   The service pipe shall be placed at least 7 feet below the surface and arranged to prevent rupture by freezing, or as authorized by the Council.
      (2)   A shut-off or other stop cock with waste valve of the size and strength required shall be placed close to the inside wall of the building and be well protected from freezing.
      (3)   Copper tubing shall be used for all services of 2 inches or less, unless approved by the City Engineer. Joints on copper tubing shall be as few as possible and not more than 1 joint shall be used for a service up to 70 feet in length.
      (4)   Each joint shall be left uncovered until inspected by the city. Every service over 2 inches shall be cast iron, unless approved by the City Engineer. Connections with the mains for domestic supply shall be at least 3/4 of an inch.
   (B)   Water meter installation. Every water meter shall be installed in accordance with the following provisions:
      (1)   The service pipe from the water main to the meter shall be brought through the floor in a vertical position where the pipe enters the building. The stop and waste valve shall be 12 inches above the floor;
      (2)   The bottom of the meter shall be 12 to 36 inches above the finished floor line;

In no case shall more than 12 inches of pipe be exposed between the point of entrance through the basement floor and the stop and waste valve. A stop and waste valve ball also be installed on the house side of the meter. The city does require copperhorns; and
