If the customer suspects that the water meter is faulty, it is advisable to do a quick self test using a container that could measure volume accurately.
Note the reading on meter before starting the test. Collect water to a 5ml bottle. Take the reading again. The reading should show an amount close to 5ml. Note: while doing this self test, please ensure all other sources running the water is turned off.
If customer is not satisfied with the self test, the meter could be tested by MWSC with a fee. If the test reveals a malfunction, the fees collected will be refunded, the most recent billed amount corrected and a new meter will be installed free of cost.
