(A) In cases where the water meters fail to register the amount of water passing through them by being stopped up or from any cause whatever, the quantity used shall be determined and the charge based upon the average amount used during the 2 or more preceding months.
(B) If figures for the 2 or more preceding months are not available, the quantity used shall be estimated as being equal to the amount used during the identical time period immediately following the repairing or replacing of the meter and the charge will be made on that basis.
(C) In case of breakage, of stoppage, or any other irregularity in the meter installed by the city, the owner or consumer is to immediately notify the Water Department.
