A standard toilet, made before 1994, uses five to six gallons of water per flush. If you don't want to purchase a new toilet, most local governments provide retrofit kits to convert your existing toilet into a low-flow toilet. Contact your local water utility for more information. Showerheads A family of four each taking a five-minute shower uses 75 or more gallons of water daily, with a showerhead manufactured prior to 1994. In addition, with the new low-flow showerheads, you no longer have to give up water pressure to save water.
Many local governments provide retrofit kits to restrict the flow on old showerheads.
Water-efficient aerators on faucets help stop money from going down the drain. A traditional faucet with an aerator, one manufactured before 1994, can use 25 gallons per day. Water-efficient faucets with aerators, those manufactured during or after 1994, can reduce water use by 25 percent. You can retrofit your traditional faucet with water-efficient aerators that can be purchased at your local hardware store.
