The code compliant approach shall be to install combined building water service capable of meeting the larger of the domestic or fire suppression system flow requirements, following the rationale that the domestic service and fire service supplies will not be flowing at design capacity at the same time.
(A) The connection from the main to the service cock shall be placed at least five feet below the level of the ground. The copper pipe shall be laid sufficiently waving so that it is at least one foot longer than if laid straight, and placed in a manner as to prevent rupture or breakage from settling of the ground.
(B) The service shall be Type K copper, minimum one inch.
(C) All copper pipes and all connections shall have wiped joints.
(D) A stopcock, to be known as the service cock, shall be inserted in each connection at a convenient point in the street, alley, public ground or place through which the connection passes, and whenever there are curb lines established, the service cock shall be placed not less than one foot or more than three feet inside of the curb line with the cast iron stop box to grade. In all cases, the service cock shall be located under the direction of the Director of Public Works, and a record of the exact location thereof shall be kept.
(E) There shall be a stop and waste cock attached to every supply pipe at the point where it enters a building in a manner as to permit the water to be shut off in cold or freezing weather and the pipes to be emptied. The separate shut off for the domestic line is required and must be accessible from the outside of the building by the city.
(F) All stopcocks used in connection with the waterworks and sewerage system or plant shall be “round way” and made of good brass, and shall be of a quality known as “standard.” They shall be strong enough to withstand a pressure of 300 pounds per square inch.
