If a meter has been tested at the request of a consumer and shall have been determined to register “fast”, the city shall credit the consumer with a sum equal to the percent “fast” multiplied by the amount of all bills incurred by said consumer within the three months prior to the test, and if a meter so tested is determined to register “slow”, the city may collect from the consumer a sum equal to the percent “slow” multiplied by the amount of all the bills incurred by the consumer for the prior three months.
(Prior Code, § 2.29)
