Every service pipe must be laid in such manner as to prevent rupture by settlement. The service pipe should be placed not less than seven feet below the surface in all cases so arranged as to prevent rupture and stoppage by freezing. Frozen service pipes between the main and the building shall be the responsibility of the owner. Service pipes must extend from the curb stops to the inside of the building; or if not taken into a building then to the hydrant or other fixtures which they are intended to supply. A valve, the same size as the service pipe, shall be placed close to the inside wall of the building, ahead of the meter and well protected from freezing. Joints on copper tubing shall be flared or compression-fitted, and kept to a minimum. Not more than one joint shall be used for a service up to seventy feet in length. All joints shall be left uncovered until inspected. Minimum size connection with the water mains shall be three-quarter inch in diameter.
