Toilet flushing is the single highest use of water in the average home, so it also presents a prime opportunity for water conservation. With the average person flushing five times a day, toilets make up about 31% of overall household water consumption.
There are lots of ways to conserve toilet water use, from habit changes and mechanical adjustments to replacement. Home Water Works gives you the information you need to maximize toilet water use efficiency in your home.
Toilet Water Saving Tips
- Install a new WaterSense labeled high efficiency toilet (HET) model to save water.
- Do not use the toilet as a trash can. Trash should be discarded in the garbage.
- If you hear the water running in the toilet tank for an unusual length of time, a simple adjustment can return it to normal operation.
- If your toilet has a water line indicator on the tank, make sure the water is at or below this line when the toilet refills.
- If your home has a dual flush toilet try to use the low volume flush mode as much as possible. Experiment to see how much the low flush can handle.
Potty Smarts: Know Your Toilet
In a home with older toilets, an average flush uses about 3.6 gallons (13.6 liters), and the daily use is 18.8 gallons (71.2 liters) per person per day. In a home with ultra-low-flow (ULF) toilets, with an average flush volume of 1.6 gallons (6 liters), the daily use is 9.1 gallons (34.4 liters) per person per day. A family of four using an older toilet will use approximately 26,000 gallons (98.4 m3) per year in toilet flushes, while a family with a ULF toilet will use approximately 11,000 gallons (41.6 m3) per year in toilet flushes, achieving a savings of 15,000 gallons (56.7 m3) per year.
