Checking For Leaks

If your water bill is unusually high, you may have a leak. Leaks can commonly occur in the following places:

  • Toilets - The flapper is the most common source of problems. Turn the water supply valve off at the toilet and watch the level in the toilet bowl. If the level drops, replace the flapper and clean the flapper seal in the toilet tank. In addition, check the level in the tank. After flushing, the water should shut off when the tank level is about ½ inch to 1 inch below the overflow. If water does not shut off at this level, adjust the float in the toilet water tank. Use the dye test to confirm a toilet leak.  Dye packets and instructions are available upon request.
  • Water Softeners - After the softener has regenerated, check to see if water is still running down the drain. If it is, the softener needs to be repaired.
  • Dripping Faucets should be repaired or replaced.
  • Furnace Humidifier - Inspect the humidifier float to make sure that it is shutting off the fill water at the level recommended by the manufacturer. Check your owner's manual for details.

An easy way to check for a leak is to perform an Overnight Leak Check.

  • Locate your water meter inside your house.
  • Read and record it in the evening when done using water for the day. If you have a softener, pick a day that your softener will not be regenerating.
  • Read the meter again in the morning before you use any water. If your meter reading changed overnight when no one was using water, you have a leak.
