Don’t ask how I know, because I’ve already been in your shoes before.

The truth is, a toilet flapper is an important element in the constituents of your toilets and provides an efficient sewage disposal system, so it’s something that needs urgent attention. It is an intrinsic part of a toilet that helps to cleanse and culvert water from the toilet tank into the bowl. This flapper is joined to the tank lever with the aid of a small chain where it carries out its function. You can get the best toilet flapper that will serve you a long time without breaking a sweat if you read till the end.

A bad toilet flapper makes water flow with high pressure which wastes water. From research, up to 30 gallons of water is wasted monthly by bad toilet flappers. This means 1 gallon of water is being wasted daily by a spoiled toilet flapper. You shouldn’t fret over this because there are several options to utilize in getting our desired flappers.


Type of flappers

When talking about toilet flappers it’s vital to know the different types of flappers available based on the materials they are composed of and how best they can be put to use. They include:

  1. Rubber type

Rubber flapper beats the competition when referring to the toilet flapper with great strength. It is frequently used in toilet repair kits and has the shape of an upside-down hat. It is made with a rubber cap attached at the base of the overflow pipe by a hinge.  They are mostly used in residential buildings and initiated on the valve opening.

The rubber cover is connected to the toilet handle by a chain. When the toilet is not in use the flapper remains in position above the flush valve, retaining the water in the tank.

The chain rises when the handle is pressed, causing the flapper to be pulled open. As a result, the toilet bowl may be flushed and water can leave. The flapper returns to its original position after the tank is full, allowing water to fill it.

  1. Tank ball flapper

Tank ball flapper is made up of a rubber ball that plugs the drain hole which prevents the wastage of water. In a real sense, this flapper appears more plug shaped. However, it has a large ball with various shapes depending on the toilet’s needs.

Tank ball flapper has a specific design that can only fit into some toilets which is why it is not commonly used. This flapper system does not require a chain system but a metal rod attached to the toilet lever arm. The flush lever pulls the stopper out of the flush valve when the toilet is flushed, enabling the water to drain from the tank.

  1. Seat disk flapper

Seat disk flapper is the oldest of all types of flappers, it makes use of a plastic or rubber disk (The oldest kind of disk) to cover the toilet tank drain thereby filling up the toilet. A hinge is used to attach the plastic tube that holds the disk to the overflow tube. Once this is put in place and the toilet is washed, the rubber disk separates from the drain allowing the draining of the tank.

It uses less time which functions as a counterweight to keep the flapper open until the tank has emptied its content. Once the water has been drained from the tank, the flapper returns to its initial position allowing the tank to rise again. A counterbalance is provided by the water inside the tube. If it empties too rapidly, the drain aperture will close before the tank is empty. A weaker flush might result from this.

What to look out for when choosing the best toilet flapper.

choosing the best toilet flapper

When looking forward to buying a toilet flapper some features must be checked to ensure its usage, either its durability or size. Those features include:

  1. Materials

Some flappers are made up of both plastics and rubber. The plastic provides rigidity and ensures the flapper is connected to the overflow tube easily while the rubber ensures a tight seal is created over the flush valve by the flapper to prevent water from getting out of the tank.

The problem mostly associated with plastics and rubber is that they deteriorate over time, hence the reasons why manufacturers come up with a solution to prevent or extend the life cycle of the materials. They do this by employing materials to resist chlorine, bacteria growth, hard water, and other elements that can degrade the rubber. A flapper typically lasts for three to five years.

A leak occurs when a flapper starts to malfunction because it is unable to form a water-tight seal with the flush valve. The characteristic sound of water flowing from your toilet usually indicates that there is a leak. The toilet must often refill to maintain the tank due to a faulty flapper.

  1. Purpose

The purpose is also a major criterion when selecting the best toilet flapper. A flapper can perform many options. The first is to allow your toilet to flush. Sometimes, it also sits idly on the toilet tank valve preventing waste of water while it keeps the water full.

The flapper opens when the time is right, allowing the water in the tank to exit via the valve and flush the toilet. It then returns to its original position after the tank has been emptied.

  1. Size

When talking about sizes, we are referring to the length. Toilet flappers are mainly of two sizes the 2-inch and 3-inch types. Majorly toilet flappers are 2-inches while only a few people have 3-inch sizes. However, It should be noted that both are good but the larger the size the greater force it will use to flush with less water.

The drain opening at your tank bottom would help you determine the size of flush valve you need. A 2-inch wide is about a baseball-sized aperture while the 3-inch opening can be compared to a grapefruit in size. You may also use a tape rule to measure the diameter of the tank’s bottom hole.

  1. Closing time

The closing time range of a flapper shouldn’t be taken lightly as it dictates the mode of operation and the efficiency of the system. This is why the closing time is to be checked before buying a toilet flapper. If its closing time is too small, and the flapper closes before the tank empties, the power of the flush will be affected.

This can result in clogs or buying another flush when the original one is no longer useful. In some cases, it can cause fresh water entering the tank to get drained leading to water wastage and an increase in water bills. You can go for flappers with an adjustment dial too. It adjusts the rate of air escape from the flapper’s valve and this affects how long it takes before the flapper shuts.

The flush volume can be controlled with the adjustment dial which means the flushing power will increase. Some toilet flappers may have floats attached to the chain to increase their flushing power. As a person looking for the best toilet flapper, you can look into these closing time factors to choose the right one for you.

  1. Fill valve repair

One of the major components of a toilet tank is the fill valve. The fill valve performs the function of refilling the tank after being emptied through the flush valve. It’s only ideal that you have a repair kit for your flapper even if you want to replace it.

It is essential to replace all the components in a toilet tank when installing a flapper. This will give you a clearer view of where faults might come from.

  1. Warranty

There are different flapper types in the market with different durability and size. So, it might be hard to choose the one that is best for you. However, it is paramount that you check the warranty each product offers before making a purchase, it will allow you to return it if it doesn’t fit into your toilet. A review of the product is also essential to check.
