Register of meter to be evidence

(1) Where a licensee supplies water by meter, the register of the meter shall be sufficient evidence of the quantity of water consumed unless the contrary is shown. (2) Any question arising between a licensee and a consumer with respect to the quantity of water consumed may, on the application of either party, be determined by the P.U.C. (3) Where the meter on being tested is proved to register incorrectly to any degree exceeding five per cent– (a) the meter shall be deemed to have registered incorrectly to that degree since the last occasion but not before the date of the test on which a reading of the index of the meter was taken by the licensee unless it is proved to have begun to register incorrectly on some later date; and (b) the amount any refund to be made to, or of an extra payment to be made by the consumer, shall be paid or allowed by the licensee or paid by the consumer, as the case may be, and in the case of an extra payment, shall be recoverable in the manner in which water rates are recoverable.
