Factors to Consider Before Buying Toilet Flappers

a) Size

Most flappers work with the standard 2-inch size. However, there are some toilets with different flush valve sizes that need their flappers. In addition, some flappers are size-specific and need to be matched correctly with the toilet.

The size of the flapper will determine how well it will sit in the tank. If the tank ball is not compatible with the tank, there will be endless leakage. There are flappers meant for two-piece toilets. The sizes will slightly vary. The flapper needs to be the exact size for the toilet to work seamlessly.

b) Material

The material used to make the flapper matters a lot as the flapper will mostly be staying in the water. Water is treated using different chemicals, including chlorine, that are corrosive in the long run. However, the material used should be able to withstand water for a long time.

Hard water, well water, or any other kind of water will eventually take a toll on the flapper. Therefore, a flapper that is made out of rubber is longer lasting than any other material. The rubber is chlorine resistant and does not get worn out easily over time. As a result, the flapper will not get affected by bacteria that might be in the water.

The material used to make the flapper is either flexible or not. The flexible material can fit easily into holes and has a surface that can remain watertight for a long period. The chain needs to be made with stainless steel that does not rust easily.

c) Compatibility

Toilet flappers are parts of a toilet that work with other parts. The better the flappers fit during a toilet flapper replacement, the more seamless the whole system will work. Loose replacement toilet flapper leads to leaking of the whole system. Leaking leads to the wastage of water and money.

Flappers can either be 2, 3 inches, or larger. A small or oversized flapper will not open and close seamlessly, leading to less pressure on the water entering the toilet bowl. A leaky flapper is a flapper that probably did not fit well in the tank. The tank ball needs to sit well in the toilet for the efficient functioning of the whole system.

d) Easy Installation

A broken flapper is not reason enough to call a plumber and pay them for a repair. You can save your money as flappers are simple to install and operate. A simple YouTube tutorial will work for anyone who is not sure about what they are doing.

A good flapper does not need any tools for installation. For example, a toilet tank flapper has clips to hold the flapper after installation for more efficiency and durability.

e) Water Type

The type of water coming into the tank affects how long the flapper will last. Water has a huge effect on the materials it stays in contact with. Ceramic is probably the best answer but, a flapper can not be made of ceramic. A flapper stays in the water all the time and stays soaked unless the tank is empty.

Polyethylene or plastic works well as they do not get corroded easily by water. However, rubber is better for compatibility.

Well, water contains different chemicals from the ground. The water might be salty and filled with different compounds that seep into the well from the ground. The water can harbor different kinds of bacteria that lead to the reduction of the flapper-life.

For anyone living near the coast, the water will take a toll on the metal chains on the flapper. Steel tends to rust faster when exposed to ocean water compared to other kinds of water. The water needs to undergo a lot of treatment to prevent the formation of scum and other forms of residue. Hard water affects the flapper.

f) Warranty

A warranty ensures that you get the best product in the market. There are many products, and it is hard to know which one is the best for your use. A warranty gives you a chance to return the product if it does not fit into your system. Check product reviews before making any purchase.
