Water Leak Detection

Houses With an Inside Water Meter


  • Turn off all the faucets in the house.
  • Check the water meter to see if the flow detector is moving. The flow detector is a small black triangle or a small red dial on the water meter. Check to see if it is moving.
  • If the flow detector moves, then stops, then moves again, this is a good indication that the toilet valve is leaking or that there may be a very small leak.
  • If the flow detector moves slowly, this is a good indication that there is a small leak.
  • If the flow detector moves rapidly, this is a good indication that there is a break in the water line. Check for soggy areas in the yard or under the house.
  • If a leak is indicated but the location of the leak is not evident or the homeowner is unable to fix the leak, contact a professional such as a plumber who specializes in leak detection and repair.
  • After the repair is completed, call the Allegany County Tax and Utility Office to discuss the possibility of a one time only leak adjustment on your bill.
