Customers shall, at their own expense, install and maintain all pipes, connections and fixtures from the service cock or meter placed by the utilities division. All pipes must be provided with stop and waste valves, protected from freezing, and accessible at all times to the customer, in such a manner that the pipes may be drained to prevent freezing and the water may be shut off for repairs to service pipes, fixtures and appliances, and also to safeguard premises from water damage in case the service cock or meter is accidentally turned on. Additional stop and waste valves shall also be placed at all low points in the pipes when they cannot be otherwise drained. Each outside hose bib shall be preceded by an additional stop and waste valve. The utilities division shall refuse to turn on the water until the provisions of this section are complied with. (Ord. 1237-86 § 22, 1986.)
