Section 4-157-11 - Meter tests and adjustment of bills for inaccuracy of measurement(a) All meters are tested prior to installation. Any consumer who, for any reason, doubts the accuracy of the meter serving the consumer's premises may request a test of the meter. The requesting consumer will be notified as to the time of the test and may witness the test. There will be a charge for meter tests to defray the cost.(b) If, as a result of the test, the meter is found to register more than two per cent fast under conditions of normal operation, the department shall refund to the consumer the overcharge based on past consumption for a period not to exceed six months, unless it can be proved that the error was due to some cause for which a specific date can be determined, and the cost of the test. Any overcharge shall be computed back to but not beyond, the determined date.[Eff MAR 17 2006] (Auth: HRS § 167-5) (Imp: HRS §§ 167-5, 167-6, 167-11, 167-19)
