What Is a Flapperless Toilet?


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.
