Many manufacturers make toilet flaps, so finding the right one can be a small challenge, especially if you plan to install it yourself, but it’s easy, but you don’t know much about them. Choose the best toilet flaps of 2019 here.

How to choose the best toilet flap

To take advantage of all the benefits associated with toilet flaps, you should consider the following before buying them.


Toilets come with flush valve drains of various sizes, the most common of which are 2-inch and 3-inch. As such, the valve comes in different sizes, and you should match these sizes before buying one. A good valve causes small valve leaks when the valve is large when it is not fully installed on the valve, but this is always true.


There are two main types of toilet flaps: regular and non-adjustable. With adjustable valves, you can adjust the flashing volumes by saving more water. These are more suitable, with 1.28 to 1.6 gallons per flush.

The non-adjustable valve has a constant flush volume and is suitable for 3.5 to 5 gallons per flush. The type you choose should determine the amount of water your toilet draws, as well as the amount you want to save on water bills.

Toilet flaps can be adjustable or non-adjustable, and it is built with different flush capabilities.

Adjustable valves are suitable for toilets that use 1.28 gallons to 1.6 gallons of water per flush. Thus, adjustable valves are available in style and size.

On the other hand, non-adjustable valves are made for toilets that use about 3.5 gallons to 5 gallons of water per flush. Both styles are made of non-adjustable valves but only 2 inches in size.


It is very important to consider the frame of a valve. Flexible frames are usually made from factor flexible pure rubber, which can adapt to many valve openings. The rigid frame is usually plastic, with rubber or silicone seals for a rigid fit.

Solid frames can not only fit into their respective sized valves but also work much better for opening ceilings. If you know the size of the flush valve in your toilet, it would be wise to opt for a specific frame. Otherwise, a rubber valve will do.

When buying a toilet flap, also consider the type of frame, such as rigid or flexible. A flexible frame comes with pure, durable rubber. And the best thing about these flexible frames is that they can fit with most flush valve drains.

You can also choose the rigid frame, which is made of hard plastic. Rigid frames provide more durability and are also designed to prevent leakage.


Durability directly determines how long the valve will last before the need for replacement. When checking for durability, look at the frame material as well as the chain. For frame material, plastic is more durable than rubber, and stainless steel chains are better off than plastic chains.

A more durable and recommended alternative is steel cable, although it is very rare. For discipline, make sure you get a mustache-free chain so that it doesn’t interfere with and affect your flushing in the process.

Price range

As for the price, you get what you pay for. Toilet flaps are relatively inexpensive. You can find cheaper toilet flaps than our top 8, but most of them are made from cheap quality materials.

If you choose a good toilet flap, it will provide you perfect service for decades! So choose the right one and stay hassle-free.


Manufacturers typically produce two-size valves for 2-inch valve drains and 3-inch valve drains. Note that 2 inch valves come with flexible and rigid frames, whereas 3 inch valve drains are accessible in rigid frames.

Types of toilet flaps

Choosing the right type of toilet flap is vital. Otherwise, a poorly adjusted valve could leak the toilet into your bathroom. To avoid wasting water and your money, you should choose the perfect toilet flap that is compatible with your toilet.

This is why you need to know the types of toilet flaps to choose the one that is suitable for your toilet. There are three types of toilet flaps:

Seat-mounted toilet flap

The oldest type is the seat-mounted toilet flap. It has a small circular disc that covers the flood pipe and prevents water from passing through it. The valve detects the flood pipe while flushing the toilet.

The water storage in the tank acts as a pressure to keep the valve unlocked when you wash it. However, after washing, the water storage becomes empty.

Our first choice for this type: Fluidmaster 5103 American Standard

Tank ball valve flap

This type of valve is located on the top of the flood pipe. After washing the rest, the ball of the tank is pulled by a chain and goes out of the flood pipe. Thus, water can enter the bowl through the tank.

In this type of case, you need to make sure that the chain keeps the rubber ball at the correct length. Otherwise, it will not work properly to pull the chain as well. As a result, lots of water can be wasted!

Our choice for this type: Lavelle 52p Blue Vinyl Tank Ball Flapper

Rubber Toilet Flap

Most of the present-day toilet manufacturers have used this type of rubber toilet flap. So if your toilet has recently been replaced with a new one, this is your type. The process is almost similar to a tank ball valve.

These types of bullets attach a cap to the flood pipe instead of just bullets. So when you flush, it slides a chain attached to the plug to lift it.

After washing, the simple cap is back in place. One thing not to forget: not all valves are made with full rubber instead of the outer edges to seal each other tightly!

Top choice of this type of toilet flap: Fluidmaster 502P21 2 inch toilet flap
