How to Save Water in a Toilet

Toilet use accounts for as much as 28 percent of water used in the average home. Improperly using toilets or neglecting to make necessary repairs can cost you money each year and increase your household's environmental impact. If your toilet needs frequent repairs and maintenance, upgrade it to a newer, water-efficient model. Low-flush toilets use only 1 to 2 gallons of water per flush instead of the typical 3 to 5 gallons.

Maintaining your toilet can reduce your monthly water bill.
  1. Call a plumber if your toilet constantly runs. Repairing this problem can save 300 gallons of water per month or more, according to the website Water: Use It Wisely.

  2. Use the toilet only for its intended use, not as an ashtray or wastebasket. Every time you use the toilet to flush facial tissue, a cigarette butt or piece of trash you waste water.

  3. Place a bucket in your bathtub to catch excess water while you shower. Use the water to flush the toilet the next time you use it. Do the same with the water you use to mop the floor.

  4. Fill a plastic water bottle with pebbles and water. Place the bottle inside your toilet tank, making sure it doesn't disturb the working parts. The bottle will displace water inside the tank, saving the average home 10 gallons a day.

  5. Replace the toilet flapper if it doesn't close properly after flushing.

  6. Place a few drops of blue food coloring in your toilet tank. Wait 30 minutes. If the food coloring seeps into the toilet bowl without your flushing it, you have a leak. Repairing it can save up to 1,000 gallons per month.

  7. Reduce the amount of water in each flush by inserting a displacement device in the tanks of toilets installed before 1992.
