Get Tanked—Save $35
If you have an older toilet that uses more than 1.6 gallons per flush, try using this MacGyver method to minimize water use. Buy a tank displacement bag or fill a half-gallon glass or plastic bottle with water (don't use a brick) and then place it in the toilet tank away from the moving parts. The half-gallon of water you displace in the tank will be saved every time you flush, which will save you nearly 8,700 gallons of water and up to $35 on water and sewage costs per year for a family of four—even if no one flushes less than normal.
