The Facts on Leaks

• The average household's leaks can account for more than 10,000 gallons of water wasted every year, or the amount of water needed to wash 270 loads of laundry.
• Household leaks can waste more than 1 trillion gallons annually nationwide. That's equal to the annual household water use of more than 11 million homes.
• Ten percent of homes have leaks that waste 90 gallons or more per day.
• Common types of leaks found in the home include worn toilet flappers, dripping faucets, and leaking shower heads. All are easily correctable.
• Fixing easily corrected household water leaks can save homeowners about 10% on their water bills.
• Keep your home leak-free by repairing dripping faucets, toilet flappers, and showerheads. In most cases, fixture replacement parts don't require a major investment.
• Most common leaks can be eliminated after retrofitting a household with new WaterSense-labeled fixtures and other high-efficiency appliances.

Leak Detection

• A good method to check for leaks is to examine your winter water use. It's likely that a family of four has a serious leak problem if its winter water use exceeds 12,000 gallons per month.
• Check your water meter before and after a two-hour period when no water is being used. If the meter does not read exactly the same, you probably have a leak.
• One way to find out if you have a toilet leak is to place a drop of food coloring in the toilet tank. If the color shows up in the bowl within 15 minutes without flushing, you have a leak. Make sure to flush immediately after this experiment to avoid staining the tank.

Faucets and Showerheads

• A leaky faucet that drips at the rate of one drip per second can waste more than 3,000 gallons per year. That's the amount of water needed to take more than 180 showers!
• Leaky faucets can be fixed by checking faucet washers and gaskets for wear and replacing them if necessary.
• A showerhead leaking at 10 drips per minute wastes more than 500 gallons per year. That's the amount of water it takes to wash 60 loads of dishes in your dishwasher.
• Most leaky showerheads can be fixed by ensuring a tight connection using pipe tape and a wrench.

Toilets

• If your toilet is leaking, the cause is often an old or faulty toilet flapper. Over time, this inexpensive rubber part decays, or minerals build up on it. It's usually best to replace the whole rubber flap - a relatively easy, inexpensive do-it-yourself project that pays for itself in no time.

Outdoors

• An irrigation system should be checked each spring before use to make sure it is not damaged by frost or freezing.
• An irrigation system that has a leak 1/32nd of an inch in diameter (about the thickness of a dime) can waste about 6,300 gallons of water per month.
