Different Types And Sizes Of Flush Bottom Valve With Handle

It is not always easy to own a house, no matter how sophisticated it may sound. Owning a home comes with a lot of responsibility, including continuous maintenance around the house.


To fix a broken toilet, you need specific knowledge since there are several things to consider. This may sound normal when repairing a broken chair or splintered door handle, but what about if you have to fix a broken chair? You will learn about the different types and sizes of flush valves in this article.


Located at the bottom of the tank in a hole, the toilet flush Bottom valve controls the flushing action. The main purpose of this device is to allow water to enter the bowl. Over the valve, a rubber flapper maintains a water-tight seal that keeps the water inside.


When the toilet handle is lifted, water rushes into the tank, and when the flapper is lowered, the flow stops. The larger valve provides a faster flush by moving water more quickly among the different sizes of valves. Ensure that the new flush valve fits the existing toilet when replacing the flush valve.

Different Sizes Of Toilet Flush Valves


  • Standard flush valve: This is the most common type of flush valve found in low-flow toilets and older toilets with large tanks. This size of the valve is used in most washrooms. With an inch valve, the flapper lifts when the toilet handle is pressed down. Homeowners can change this flush valve themselves. It is very easy to do.

  • Flush valves with an inch diameter are larger than standard flush valves. In addition to having a larger hole, a 3-inch valve allows for greater water drainage volumes. It is possible to ensure faster draining of water by using a 3-inch flush. With this valve, you can flush effectively while using less water overall. Three-inch valves are replaced similarly to two-inch valves.

  • A dual flush valve is found in any toilet that has a double flushing option. With this type of valve, liquids and solids can be flushed half way (for liquids) and fully (for solids). A handle on some dual flushes gives a full flush when pressed down, and a half flush when pushed up.

Different types of Flush Valve

Tank ball type flush valve


  • There is a flush handle on the outside of the toilet that lifts the tank ball at the bottom via a trip lever attached to a rod or chain. The trip lever opens the valve when the toilet is flushed, flushing the waste through the waste pipes. When the float ball is lowered along with the water level, the water valve is opened, allowing water to enter the tank.

  • Once the tank is emptied, the ball sticks to the rim of the valve and seals it. Its buoyancy is maintained by the air inside the tank ball. A few factors can compromise the function of the tank ball, such as chlorine in the water, which causes it to harden and lose its shape, and premature deterioration.

Flapper type toilet flush valve


  • The rubber flapper at the bottom of the tank is used instead of a tank ball in this type of flush valve. Two materials make up these flappers; plastic with a rubber seal at the bottom and silicone. A person must carefully select the type of flapper they need since there are different flappers for different toilet types, and they are not interchangeable.

  • The flapper valve works similarly to the tank ball; when it is raised, the reservoir opens and water is flushed down. In this model, the flapper remains open until the tank's water level has decreased to the point of being empty, after which the flapper closes the drain opening and allows the tank to reload.
