Your toilet could save you money Fixing leaks is often an easy and inexpensive way to get some remarkable water savings, but did you know that replacing fixtures can produce savings as well? For example, a family of three that replaces toilets using five gallons per flush with new ones, which use 1.6 gallons, could save more than 15,000 gallons or about $100 per year. Toilet use accounts for about 30 percent of water used in the home. Find other ways you can conserve water.
