How to Tell What Size Flapper for Toilet?

A toilet flapper is a small rubber disk that sits between the toilet tank and the bowl. When you flush the toilet, the flapper opens, allowing water from the tank to flow into the bowl. The flapper then closes, stopping the flow of water.

Over time, the flapper can wear out and become leaky. This can waste water and lead to higher water bills. It can also cause the toilet to run constantly, which can be a nuisance.

If you think your toilet flapper is leaking, you can usually fix it by replacing it with a new one. But before you do, you need to know what size flapper you need.

This article will show you how to tell what size flapper for toilet you have. We’ll also discuss how to replace a toilet flapper.

How To Tell What Size Flapper For Toilet?

Identify the type of toilet

The first step to finding the right flapper for your toilet is to identify the type of toilet you have. There are two main types of toilets:

  • Siphonic toilets use a siphon to create a vacuum that pulls the water out of the bowl. This type of toilet is more common in older homes.
  • Vortex toilets use a swirling motion to create a vortex that pulls the water out of the bowl. This type of toilet is more common in newer homes.

To identify the type of toilet you have, look at the back of the toilet. You should see a label that says either “Siphonic” or “Vortex.”

Measure the flapper height

Once you have identified the type of toilet you have, you need to measure the flapper height. The flapper height is the distance from the top of the toilet tank to the bottom of the flapper.

To measure the flapper height, use a ruler or tape measure. Place the ruler or tape measure on the back of the toilet tank, just below the overflow pipe. Then, measure the distance from the top of the ruler or tape measure to the bottom of the flapper.

The flapper height should be between 13 and 15 centimeters. If the flapper height is too low, the toilet will not flush properly. If the flapper height is too high, the toilet will leak.

Choose the right flapper

Once you have measured the flapper height, you can choose the right flapper for your toilet. You can find flappers at most hardware stores.

When choosing a flapper, make sure to choose one that is the correct size for your toilet. You should also choose a flapper that is made of a durable material, such as rubber or plastic.

Here are a few tips for choosing a flapper:

  • Choose a flapper that is made of a durable material. Rubber and plastic are both durable materials that will last for many years.
  • Choose a flapper that is the correct size for your toilet. The flapper should fit snugly against the flush valve.
  • Choose a flapper that is easy to install. The flapper should be easy to install so that you can replace it quickly if it breaks.

Install the flapper

Once you have chosen the right flapper, you can install it on your toilet.

To install the flapper, follow these steps:

1. Turn off the water supply to the toilet.
2. Remove the old flapper.
3. Clean the flush valve.
4. Apply a thin coat of plumber’s grease to the flush valve.
5. Position the new flapper on the flush valve.
6. Secure the flapper with the flapper chain.
7. Turn on the water supply to the toilet.

The flapper should now be installed and working properly. If you have any problems installing the flapper, you can consult a plumber for help.

Knowing how to tell what size flapper for toilet is important for ensuring that your toilet flushes properly and does not leak. By following the steps in this guide, you can easily identify the type of toilet you have, measure the flapper height, and choose the right flapper for your toilet.

Here are a few additional tips for maintaining your toilet:

  • Flush the toilet regularly. Flushing the toilet regularly helps to keep the water in the tank clean and prevents bacteria from growing.
  • Clean the toilet bowl regularly. Cleaning the toilet bowl regularly helps to remove dirt, grime, and bacteria.
  • Replace the flapper regularly. The flapper should be replaced every 5 to 10 years.

By following these tips, you can keep your toilet in good working order and prevent problems from occurring.

Determine the flapper width

The flapper width is the measurement from the center of the flapper to the outside edge of the flapper. To determine the flapper width, you will need to measure the flapper itself.

To do this, follow these steps:

1. Remove the toilet tank lid.
2. Locate the flapper. It is a rubber or plastic disk that sits in the center of the tank.
3. Use a ruler to measure the flapper from the center to the outside edge.

The flapper width is typically between 1.5 and 2 inches. If your flapper is wider than 2 inches, you will need to purchase a replacement flapper that is the correct size.

Choose the correct flapper size

Once you have determined the flapper width, you can choose the correct flapper size. You can find flappers in a variety of sizes, so it is important to choose the one that is the correct fit for your toilet.

To choose the correct flapper size, follow these steps:

1. Measure the flapper width.
2. Find a flapper that is the same width as your old flapper.
3. Make sure the flapper is compatible with your toilet model.

  • If you are still not sure what size flapper you need, you can contact the manufacturer of your toilet for assistance.
