Depending on the kind of toilet you have, you use between five and seven gallons of water every time you flush.

Fill a jar or bottle with water (you can also use a brick) and place it in your toilet tank. This will take up space in the tank and trigger the water refill to stop sooner, so you’ll use less water every time you flush.

Make sure what ever you use to fill the space doesn’t come into contact with the flushing mechanism. Flush once or twice while the lid is still off and watch to make sure everything still works.

If you suspect that your toilet leaks water into the bowl between flushes, put food coloring in the tank. Wait awhile (don’t flush!) and see if the dye reaches the water in the bowl. If it does, you have a leak. You’ll need to call a plumber or study up on do-it-your-self books.

If you’re shopping for a new toilet, make sure it’s low flow.
