How to Check For and Prevent Leaks
1. Read your water meter
Even if you think you have no leaks in your home, you can check periodically using your water meter. Start by recording the reading on your meter and then do not use any toilets, faucets or appliances that require water for approximately 30 minutes. After that time take a look at the reading again. If the dial has moved, there is a leak.
2. Check and repair leaky faucets
A dripping faucet or shower head usually makes itself known with an annoying dripping sound, but if you are unsure, leave a bucket or bowl under it for a period of time to see if any water collects. Replacing the rubber "O" ring or washer inside the valve can usually repair dripping faucets in your sinks and bathtub faucets.
3. Check and repair leaky toilets
To check toilets for leaks, place a few drops of food coloring in the toilet tank. Check again after 15 minutes - if any dye shows up in the toilet bowl, the toilet has a leak. Replace flappers every 4-5 years.
If you are unable to find the source of a leak or to repair it yourself, call a plumber - it will cost you less in the long run!
