10 Best Toilet Flappers to Buy in 2024, With Reviews

If your toilet keeps leaking or you hear a monotonous hissing sound, it may be time to replace the toilet flapper. Toilet flappers are an integral part of the toilet because they can flush and drain water from the tank into the toilet bowl. The flapper is attached to the tank lever by a small chain. However, the flapper will degrade over time and cause noise and leaks. This leads to water wastage.

With the correct type of flapper, you can overcome these problems immediately. Choose the best toilet flapper from our list and test them out.

Types Of Flappers

There are three types of toilet flappers that provide different functions.

1. Rubber flapper

The flapper made of rubber resembles the shape of an upside-down hat. It is usually installed on the valve’s opening and used in toilets. There is a small hole at the bottom of the model that allows water to flow. The water, when flushed, enters the hat and increases the weight. When the reservoir tank reaches full storage capacity, the flapper eventually lowers, thereby closing the valve. The rubber flappers last long and are adjustable.

2. Seat disk flapper

This is the oldest type of flapper for older toilet models and has the oldest kind of disk that fits and snaps above the valve. The flapper’s lever system can lift the disk during flushing and then lower it again to fill the water tank. It is made of a strong piece of rubber and easy to replace. However, several parts attached to the level system may make the device bulky.

3. Tank ball flapper

This type of flapper design can fit specific toilets, so it is not common. The tank ball flapper has a large ball with various shapes. It does not require any chain system because it can be attached to the lever arm by metallic rods screwed into the tank’s top.

How To Choose The Right Toilet Flapper?

Before buying the best toilet flapper, consider the following factors.

  1. Size: Finding the right flapper size is crucial. The size of the valve will determine the flapper you need. If the flapper is too small or too large, the seal may loosen, and the leaking problem may persist. Some flappers can fit the two-inch valves, while some can comfortably fit the two-inch valves.
  2. Quality: Choose high-quality products made of chemical-resistant and water-resistant materials. The best flappers prevent mildew. Rubber, silicon, or plastic products are trustworthy and durable.
  3. Age of your toilet: Before buying a toilet baffle, check the age of the toilet since many old toilets may use old-fashioned toilet flappers, or new flappers may not fit them. Review and research your needs, then buy the best flapper accordingly.
  4. Type: There are adjustable and non-adjustable toilet flappers. You need to know the amount of water the flapper can flush to understand its type. Non-adjustable flappers are limited to two-inch valves.
