Standard toilets often leak when a component becomes worn out, including toilet "flappers." New toilet designs use the "tipping bucket" concept instead of flappers.
What it is
A "flapperless" toilet is one without a rubber flapper and seal in the toilet tank to control the flow of water from the tank into the bowl.
How it Works
A gravity flush toilet uses a "tipping bucket" to control water flow. Water fills a bucket at the top of the tank. The flush lever tips the bucket and the water flows from the tank into the bowl.
There is no seal, ball, valve or flapper in a flapperless toilet; leaking is far less likely from an upright bucket. Parts also last longer because they are not submerged in water. The toilet is low-flow, using only 1.28 or 1.6 gallons per flush. Also, the lever can be on the right or left of the tank.
Niagara Conservation Corporation makes flapperless toilets.
