Possibly but in most cases No. Older mechanical meters tend to lose accuracy as they age and, therefore, may not accurately measure all the water being used. The new water meter will accurately measure the water that you use. All new meters are tested prior to delivery by the manufacturer to ensure that they register properly. If you see a higher bill immediately upon the new meter installation and you have not changed your water use pattern, it is likely the old meter was running slow, or you have a minor leak in the system that wasn’t registering correctly through the old meter. The benefits of improved and more accurate usage information to the Utility and customers will reduce wasted water through the enhanced system capability to send alerts and notifications such as stopped meter, customer leak detection, and utility distribution system leak detection.
