Buying Guide


Before buying a flapper to repair your toilet, there are particular factors you might wish to consider. Flappers come in various sizes to match various-sized flush valves. Some use substances that improve their durability, plus a few provide features that let you maximize your toilet’s water use.


A toilet flapper lets your toilet flush out. The flapper sits in place within the toilet tank drain valve most of the time, preventing water from penetrating while maintaining the tank full. When it is time for actions, the flapper opens, along with the water from the tank flows via the valve, causing the toilet to flush out. When the tank has drained, the flapper falls back to position within the valve, permitting it to refill.


Flappers are made from a blend of rubber and plastic. The plastic provides rigidity, which makes it possible for the flapper to attach to the overflow tube. The rubber makes it possible for the flapper to make a tight seal within the flush valve, preventing water from penetrating the tank. Even though flappers consist of high-quality plastic and rubber, they will worsen over time. Producers want to extend the life span using substances that resist bacteria growth, chlorine, hard water, and other components that may hamper the rubber.

A normal flapper lasts between five and three decades. When a flapper starts to fail, it loses its capacity to make a water-tight seal using the flush valve, leading to a flow. You may typically tell there’s a leak on your toilet from the telltale sound of dripping water. A leaky flapper additionally results in the toilet to wash as it attempts to keep the tank full.


Flappers come in two distinct sizes: 2-inch and 3-inch. The vast majority of toilets utilize 2-inch flappers. But, there are a few that use 3-inch flappers, such as several high-efficiency toilets. The more oversized flush valve produces a more effective flush with less water.

To ascertain what size you want, examine the flush valve drain opening in the base of your tank. A 2-inch space will probably be the size of a baseball match. A bigger 3-inch opening will probably be the size of a grapefruit. You can also use a tape measure to confirm the width of the space in the base of your tank.

Final Time

Another critical element within the toilet’s tank would be the valve, flapper, and escape valve. True to its title, the valve is responsible for refilling the tank once emptied through the valve.

If you are replacing a flapper, it might make sense to substitute all of your toilet tank elements. It’s more economical to purchase the best toilet repair kit that includes the valve and flapper. Additionally, if you are replacing an older flapper that’s failing, it is an excellent bet that the valve is also close to the end of its lifetime.
