(A) Service pipes. Every service pipe shall be laid with sufficient bend to allow not less than one foot of extra length and in such manner as to prevent rupture by settlement. The service pipe shall be placed not less than six feet below the surface and be so arranged as to prevent rupture by freezing. A shut-off or other stop cork 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. Copper tubing shall be used for all services of two inches or less. Joints on copper tubing shall be as few as possible and not more than one joint shall be used for a service up to 70 feet in length. Each joint shall be left uncovered until inspected by the city. Every service over two inches long shall be cast iron, or whatever is acceptable in accordance with the State Plumbing Code. Connections with the main for domestic supply shall be at least three-fourths inch.
(B) Water meter setting. 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 no less than 12 inches nor more than 24 inches above the floor.
(2) The top of the meter shall not be over three feet above the finished floor line. The meter shall be set not more than 12 inches horizontally from the inside line of the basement wall unless a different position is approved by the Public Works Department. A suitable bracket shall be provided to support the meter in a proper vertical position and prevent noise from vibration.
(3) Each meter installation shall have a stop and waste valve on the street side of the meter. In no case shall less than 12 inches nor more than 24 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 shall also be installed on the house side of the meter.
(4) The water pipe connecting the main shall not exceed two feet under the basement wall to the water meter connection.
(5) Meter setting devices for five-eights inch, three-fourths inch, and one inch meters shall be of copper pipe or tubing from the terminus of the service pipe up to and including the stop and waste valve on the building site.
(C) Location of stop boxes. Curb stop boxes shall be installed generally where desired by the owners of occupied properties, but they shall be placed as near as possible to the curb if on a street or within one foot of the alley line if the main is located in the alley. They shall be installed at an approximate depth of six feet below the established grade and shall be left in an accurate vertical position when back- filling is completed.
