Detecting Leaks

1. Read the water meter, noting the position of the clock-style hand that records individual gallons.
   
   
2. Wait at least 15 minutes without using water.
   
   
3. Look at the meter again to see if the hand moved. If it did not, there are probably no leaks. Waiting longer between meter readings (overnight, for instance) might help you detect slow or intermittent leaks.



4. If the meter hand moved, check all of your faucets for visible leaks.
   
   
5. Check the toilets for leaks by adding food coloring to the water in the tank. Do not flush. Wait 15 minutes to see if the colored water appears in the toilet bowl. If it does, there is a leak. Repairing toilet leaks is normally inexpensive and easy to do. Replacement part kits are available at most hardware stores.
   
   
6. If there appear to be no leaks inside your home, and the meter is located outside, check for underground leaks. Turn off your main valve inside, then open a faucet to verify that the valve is working—the water flow should stop completely. Go back outside to the meter to see if it continues to run with the main valve off. If it does, there is a leak somewhere in your plumbing between the meter and the valve.
   
   
7. After making repairs, repeat the meter reading procedure to verify that there are no more leaks.
