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 the consumer within the three months prior to the test, and if a meter so tested is determined to register “slow,” the Department 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. When the Department on its own initiative makes a test of a water meter, it shall be done without cost to the consumer, other than his or her paying the amount due the city for water used by him or her as above provided, if the meter is found to be “slow.”
