§ 51.07 INSTALLATION OF SERVICE LINES AND HOUSE CONNECTIONS.
   (A)   Installation of service lines shall be at least six feet apart. All water lines shall be above the level of sewer lines by at least one foot at all crossings and where laid in the same ditch shall be placed on a shelf at least three times the width of the pipe and one foot above the sewer pipe. Exceptions may be granted by the Village Administrator.
   (B)   House connections. All house connections shall be a minimum of 3/4-inch of Type K copper tubing or polyethylene high density pipe 160# per square inch rating, known as service pipe or municipal pipe that can be flared for use with compression fittings.
   (C)   A separate service pipe must be laid from the main for each building, except that a service pipe may extend from the owner's house or place of business to his own barn or garage in the rear if desired. There shall be no combination between the curb line and the building of two or more water supply lines for the supply through a larger single line.
   (D)   No division of the water service of any lot or parcel of land shall be made for the extension and independent meterage of the supply to an adjoining lot or parcel of land without special permission of the Superintendent. No division of a water supply service shall be made at the curb for separate supplies therefrom for two or more separate premises having frontage on any street or public service strip without special permission of the Superintendent.
   (E)   Water services shall be laid on a solid ground bottom and shall have not less than three feet of ground or sand filling. When laid in a combined sewer and water trench, the service shall be laid on a shelf of solid ground not nearer than 12 inches to the side of the wall of the sewer trench.
   (F)   No water service shall be laid through any trench having cinders, rubbish, rock, or gravel fill, or any other material which may cause injury to or disintegration of the service pipe, unless adequate means of protection are provided by sand filling or such insulation as may be approved by the Superintendent. Service pipes passing through curb or retaining walls shall be adequately safeguarded by the provision of a channel space or pipe casing not less than twice the diameter of the service pipe. The space between the service pipe and the channel or pipe casing shall be filled and lightly caulked with oakum, mastic cement, or other resilient material, and made impervious to moisture.
   (G)   When a change of direction of a cast iron service is made on either side of a curb or retaining wall, the cast iron fitting shall be securely braced to prevent the loosening or blowing out of the lead in the caulking joints. The bracing shall be made by concrete backing or by clamp rods extending from the fitting bell to the next bell or fitting, or by clamp rods securely anchored in the wall. Such clamp rods should not be less than 5/8-inch diameter and, when buried in soil, should be protected against corrosion by painting with tar asphaltum or other suitable means. Set screws for fastening clamp rods to pipe shall not be permitted.
   (H)   In backfilling the pipe trench, the service pipe must be protected against injury by carefully hand tamping the ground filling, free from hard lumps, rocks, stones, or other injurious material, around and at least six inches over the pipe.
