A. Drain And Waste Cock: There shall be a drain and waste cock attached to every supply pipe at the point where it enters the building in such a manner as to allow the water to be shut off in cold or freezing weather, and the pipes to be emptied.
B. Kind And Quality Of Copper Pipe:
1. The connection from the main and all authorized branches to the inside line of the building or house shall be placed at least five and one-half feet (51/2') below the surface of the ground and shall be made of copper pipe of the quality known in commerce as "extra strong". The pipe shall be laid sufficiently wavy so that it shall be at least one foot (1') longer than if laid straight and placed in such a manner as to prevent rupture or breakage from settling of the ground. All copper pipe used for interior plumbing shall be of the same quality known in commerce as "extra strong".
2. For interior plumbing work beyond the inside of the building or house, galvanized iron pipe, joints and couplings shall be of a quality known in commerce as "standard". Other interior plumbing may be of such kind as the applicant or owner may direct, but such and all other must stand a pressure of three hundred (300) pounds to the square inch. All drain cocks used in connection with said waterworks system or plant shall be made of brass and shall be of a quality known in commerce as "standard" and shall be strong enough to resist the pressure of water in all cases.
C. Time For Connections; Size: No connections shall be made with the mains in freezing weather unless special circumstances make the same safe, and then only when approved by the superintendent. All connections where the same join the main shall be at least twenty four inches (24") apart. The opening or tap for any connection in a four inch (4") main shall not be larger than to receive a five-eighths inch (5/8") connection; for a six inch (6") main, no larger than to receive a three-fourths inch (3/4") connection; and all above six inch (6") mains, no larger than to receive a one inch (1") connection; except in mains above six inches (6") under special circumstances rendering it safe, and then only when first permitted by the superintendent, a tap to receive a larger connection than one inch (1") may be made.
D. Height Of Public Hydrants And Street Washers: All public hydrants and street washers shall extend at least five feet (5') into the ground and shall have a good and sufficient drip well surrounded with rubble stone, so as to allow free drainage of water from the bottom thereof. (1999 Code § 16.06)
