According to EPA, the average household loses more than 10,000 gallons of water each year through leaks. Some water leaks are slow and difficult to detect, yet even the smallest leaks can add up quickly. Fixing easily corrected household leaks can save homeowners about 10 percent on their water bills, and fortunately, most leaks are easy to find if you know where to look! Use EPA's at-home checklist and read some tips below to help you find leaks:
- Check your water meter before and after a two-hour period when no water is being used. If the meter changes at all, you probably have a leak.
- Identify toilet leaks by placing a drop of food coloring in the toilet tank. If any color shows up in the bowl after 10 minutes, you have a leak. (Be sure to flush immediately after the experiment to avoid staining the tank.)
- Examine faucet gaskets and pipe fittings for any water on the outside of the pipe to check for surface leaks. Calculate the water waste of a dripping faucet using the American Water Works Association Drip Calculator.
EPA has a lot of resources on finding and fixing leaks on the EPA Fix a Leak Week page, including video tutorials. Be sure to check it out!
If you've already determined you have leaks and these resources aren't enough to stop them, it might be time to contact a plumbing professional. When replacing fixtures, consider those with a WaterSense label, which could increase your home's water efficiency and lower your bill.
