Every service pipe attached to the mains shall have a curb cock, the same to be placed as near as possible to the curb, if on a street, or within one foot of the alleyline if the main is located in the alley. Every supply pipe shall have one or more stop and waste cocks attached at some point between the curb cock and the meter, so that water can be shut off and the meter and house plumbing entirely drained.
