Save thousands of gallons of water a year with a two-button conversion kit for your toilet. Originally an Australian invention, the two button toilet is becoming the standard for toilet manufacturers around the world. Designed in 1980 by Bruce Thompson, the original system used one button that flushed with 11 liters per time and another smaller button that used 5.5 liters a flush. With this simple change, the two-button toilet system helps save an average of 32,000 gallons per year.
If you want to skip the hassle of getting a new toilet, you can retrofit your existing toilet with a number of kits available in your hardware store or dual-flush conversion kit. If the process of retrofitting seems daunting, here is a video on installing a Better Fill Water Saver.
