Toilets are the single largest water user in a household. Over the course of your lifetime, you will likely flush the toilet nearly 140,000 times.
Not all toilets use the same amount of water. Toilets built before 1992 can use anywhere between 3.5 and 7 gallons of water per flush. Under current federal law, new toilets must not exceed 1.6 gallons per flush (gpf).
If you haven’t replaced your toilet in a while, you may want to consider purchasing a water efficient toilet and getting a rebate from the Water Department.
High-efficiency, third party tested WaterSense labeled toilets go beyond the standard and use less than 1.3 gpf. These toilets combine efficiency with high performance and often perform better than standard toilets in consumer testing.
