Many water leaks come from toilets that are misaligned or the tank components are worn out. Harsh water conditions, including toilet tank cleaners, cause components to break down. A toilet that continues running after the tank has refilled wastes 5-10 gallons of water per hour. That’s 44,000-88,000 gallons of wasted water per toilet, per year. Newer toilets conserve water by only using 1.6 gallons per flush instead of 3.5 gallons per flush. The average person flushes their home toilet 5 times per day. This can save nearly 3,500 gallons of water per person, per year.
