Leak Prevention and Drip Calculator

  • Pledge to fix leaks: Hidden leaks in your home can waste water and cost you money. On average, a U.S. household can lose as much as 11,000 gallons of water to leaks each year - enough to fill a swimming pool. Make the pledge to fix your leaks during the Environmental Protection Agency's (EPA) Fix a Leak Week. To find out what week it will be this year, visit www.epa.gov/watersense
  • First, shut off all the water in your home and locate your water meter. Most residential meters are located in the front sidewalk or curb area. Now, folow these tips to help you identify a leak:
    • Check you rmeter for movement. You will notice a triangle called a flow indicator. This triangle will move whenever water is passing through. No movement indicates no leak. If your flow indicator shows continuous rotation, you have a leak.
    • To tell if your toilet has a leak, place a drop of food coloring in the tank and wait 10 minutes. If the color shows in the bowl without flushing, you have a leak. Consider upgrading dripping faucets and leaky shower heads with WaterSense® products, which are tested to meet the EPA's rigorous criteria for efficiency and performance.
