Drips per minute → gallons → bill language. Proof for homeowners who hear a drip.
A faucet that drips while you sleep is continuous waste. Homeowners often hear it and dismiss it — but volume is what utilities bill. EPA WaterSense notes household leaks waste about 180 gallons per week on average, and easy fixes can save about 10% on the water bill.[1]
