Using common items around your home, you can reduce the amount of water used in your toilet, and your toilet tank.
All you need to do is fill a plastic bottle with sand or small rocks.
Remove the cover of your toilet tank and place the bottle in the water (don’t worry this water is clean!).
Toilets automatically stop flushing when the water in the tank reaches a certain level, but they are typically more full than necessary. By displacing the water with a heavy object, your toilet will work normally while using less water.
