It is unlawful to install water service without a shut-off valve on a customer line, enabling the owner to shut off water. A shut-off valve will not be permitted inside the meter box. A shut-off valve ahead of the meter is not a shut-off valve, and the closing of this valve will not protect the plumbing between the meter and house or within the house, and this valve must not be closed except in the presence of the Public Works Director, or his representative, or upon their instructions, or to avoid damage to property, in which case, it shall be the duty of the water user to notify the Public Works Division immediately of such shut-off.
