It is rare that water meters malfunction. The new meters recently installed were all tested prior to installation and are accurately registering water flowing through them. Water meters are mechanical and in most cases will slow with age rather than speed up. The new meters are equipped with leak indicators, a small blue dial on the face of the meter, if this is moving when nothing is supposed to be running in the home there may be a leak that should be investigated. If your bill is excessively high, consider having the house checked for leaks by our technician or a plumber.
