All meters shall be maintained by and at the expense of the Town insofar as ordinary wear and tear are concerned, but the owners will be held responsible for damages as a result of freezing, hot water or other external causes, when such damage results directly or indirectly from the negligence of the customer. When such damage occurs, the Town will furnish and set another meter to replace the one frozen or otherwise damaged, and the cost of such repairs, including replaced parts, labor and transportation charges, shall be paid for by the owner.
