Best Toilet Flapper – How to Choose and Replace

When we buy a toilet, we pay our attention to many factors. To choose the best toilet, we must look both on the inside and on the outside. A beautiful design and a comfortable toilet seat are just as important as a durable tank and a powerful flushing system. And every flushing system needs a toilet flapper to work.

A flapper is an essential part of the flushing system of any toilet. It is a component of the flush valve and is located in the tank. Apart from the flapper, the construction of the flush valve includes the overflow tube and the hole through which the water escapes the tank and gets into the bowl when you push the flush button. The flapper serves the purpose of covering this hole when the tank is full.

With time, toilet flappers tend to decay or store mineral build up. If the flapper is damaged, it cannot hold the water inside the tank. As a result, you get a leaky toilet. Apart from the stains that will be caused by constantly dripping water, such a leak will result in the increase of your water bill.

To fix this little problem, you will need to replace the toilet flapper. It is rather easy to find replacement parts for most modern toilets, despite their construction and flushing system. Look through our reviews to find the best toilet flapper that will be a perfect match for your toilet.

Types of Toilet Flappers2017-02-08_134222

There are three types of toilet flappers, each with unique features. Understanding the difference between them is very important to achieve the highest efficiency of the flushing system of your toilet. Knowing how different types of flappers work will help you choose the best replacement part for your toilet.

The three types of toilet flappers are:

2017-02-08_141415Rubber flappers are installed in the majority of modern toilets. They work like caps attached to the chain. When you flush, the chain lifts the flapper and lets the water through the hole and into the bowl. When all the water flushes out of the tank, the chain lowers the flapper so that it covers the hole. Flappers of this type are usually durable and reliable, as rubber is water-resistant and maintains its properties long even when it is constantly exposed to water. Another advantage of rubber flappers is their sturdy design with few moving parts.

2017-02-08_135151Seat disk flappers are the oldest among all the types. They have a different action mechanism than rubber flappers. Their construction includes a small disk that covers the overflow pipe, holding the water inside the tank. Underneath the disk, there is a plastic tube that is hinged to the overflow tube. The flappers of this type use the weight of water to open and close the tank hole. The main disadvantages of seat disk flappers are their large size and disks that get damaged quickly.

2017-02-08_141228Tank ball flappers, as the name suggests, consist of a ball that sits on top of the overflow pipe. Similar to rubber flappers, they have a chain connected to them. When you push the flush button, the flushing mechanism pulls the chain, lifts the ball off the pipe, and lets the water through. The chain should be the perfect length. Otherwise ball flappers fail to offer faultless performance. If the chain is too long, it will not be lifted when you flush, and if it is too short, it will prevent the ball from covering the overflow pipe.

How to Choose a Flapper for Your Toilet

Selecting the right flapper is very important to make sure that the flushing system of your toilet works efficiently. When you realize that the flapper needs to be replaced, you need to consider all the options carefully to choose the best match for your toilet.

When it comes to toilet flappers, there are two common sizes – two and three inches, corresponding to two sizes of overflow pipes. Two-inch flappers are usually installed in older toilets. However, some modern models also come with flappers of this size. Three-inch flappers are a part of the flushing system of most new toilets. It is critical to purchase a flapper of the right size, as a larger or smaller model will not create a tight seal.

Apart from these two standard sizes, there are odd-sized flappers. Some toilets have unique overflow pipe size and require a flapper of the same size. There are also the so-called universal flappers. Their construction allows using them with both two- and three-inch pipes. You can also choose the flapper of an appropriate size if you know how many gallons of water your toilet uses per one flush.

Please note that you should purchase a flapper of the type that is installed in your toilet. Only a flapper of the same type can be used to replace an already existing one. A rubber flapper cannot be installed in place of a seat disk or a tank ball flapper.

How to Replace a Toilet Flapper

Replacing a toilet flapper is an easy job that requires little time and effort. Virtually anyone can do it, even those of us who are not familiar with plumbing fixtures work. These simple steps will help you remove the old damaged flapper and install a new one quickly and easily.

  • Remove the lid of the tank.
