Leaky toilets and faucets can waste hundreds of gallons of water each day, and that means paying for unnecessary water and sewer charges. For example, did you know:

• A 1/8-inch hole in a metal pipe, at 40 psi (pounds per square inch), leaks 2,500 gallons of water every 24 hours.
• A leak the size of a pinhead can waste 360,000 gallons a year, enough to fill 12,000 bathtubs to the overflow mark. For example, a leaking toilet can use 90,000 gallons of water in 30 days.
• A dripping faucet/hose bibb can lose up to 180 gallons a month, or 2,160 gallons per year.
• About 1 in every 20 pools has a leak.
• About 1 in every 318 homes or buildings has a leak.

To help you identify and repair any leaks in your home, try these tricks:

• Make sure no water is running in the house, then observe your water meter. If you see the meter’s readout increasing and/or a dial spinning, you may have a leak.
• Check toilets for silent leaks by putting a few drops of food coloring in the toilet tank after it has filled. If coloring shows up in the bowl without flushing, you probably have a leak in or around the flapper valve. (The fix is to replace the flapper mechanism, which is easy and inexpensive.)
• Inspect the water level in your toilet tank. The correct water line is about a one inch below the top of the overflow pipe. If it is higher, water is being wasted.
• Check the faucets in your bathrooms, kitchen, laundry room and outside the house. Worn washers are the biggest cause of faucet leaks.
