How to Replace a Flush Valve Seal on an American Standard Toilet

Your toilet’s flush valve seal is a critical part of the flushing mechanism. It prevents water from leaking from the tank into the bowl when the toilet is not in use. Over time, the flush valve seal can wear out and leak. If you notice water leaking from the tank to the bowl, or if your toilet is not flushing properly, it’s time to replace the flush valve seal.

Replacing a flush valve seal is a relatively simple task that can be completed in about 30 minutes. However, it is important to follow the steps carefully to avoid damaging your toilet. In this article, we will walk you through the process of replacing a flush valve seal on an American Standard toilet.

Tools and Materials

  • Replacement flush valve seal
  • Adjustable wrench
  • Phillips head screwdriver
  • Penetrating oil
  • Rag
  • Bucket

Steps

1. Turn off the water supply to the toilet. Locate the water supply valve located under the sink or behind the toilet. Turn the valve clockwise to turn off the water supply.
2. Flush the toilet to drain the water from the tank.
3. Remove the old flush valve seal. The flush valve seal is located at the bottom of the tank, just above the drain. There will be two screws holding the flush valve seal in place. Use a Phillips head screwdriver to remove the screws.
4. Apply a small amount of penetrating oil to the threads of the new flush valve seal. This will help to make installation easier.
5. Install the new flush valve seal. Carefully insert the new flush valve seal into the hole in the tank. Once the seal is in place, replace the screws.
6. Turn on the water supply to the toilet.
7. Flush the toilet to test the new flush valve seal. The toilet should now be working properly.

Step Tools Instructions
1 Pliers Turn off the water supply to the toilet.
2 Adjustable wrench Remove the nuts that hold the flush valve in place.
3 Toilet bowl brush Clean the inside of the toilet bowl.
4 New flush valve seal Apply a thin coat of plumber’s grease to the new flush valve seal.

A flush valve seal is a rubber gasket that sits between the flush valve and the toilet bowl. It creates a watertight seal to prevent water from leaking from the toilet. Over time, the flush valve seal can wear out and become leaky. This can cause a number of problems, including:

  • Wastewater backing up into the toilet bowl
  • Water pooling under the toilet
  • A high water bill

If you notice any of these problems, it’s likely that the flush valve seal needs to be replaced. This is a relatively simple DIY project that can be completed in about 30 minutes.

Gather your tools and materials

To replace the flush valve seal on an American Standard toilet, you will need the following tools and materials:

  • Replacement flush valve seal
  • Adjustable wrench
  • Pliers
  • Penetrating oil
  • Rags

Shut off the water supply to the toilet

The first step is to shut off the water supply to the toilet. This can be done by turning off the main water supply valve to the house. The water supply valve is usually located near the water meter. Once the water supply is turned off, flush the toilet to drain any remaining water.

Remove the old flush valve seal

The next step is to remove the old flush valve seal. To do this, you will need to use an adjustable wrench to loosen the nuts that hold the flush valve in place. Once the nuts are loose, you can use pliers to pry off the old flush valve seal. Be careful not to damage the toilet bowl.

Install the new flush valve seal

Now it’s time to install the new flush valve seal. To do this, you will need to align the new seal with the toilet bowl and then screw it into place using the nuts that you removed earlier. Make sure that the seal is installed tightly.

Reattach the water supply to the toilet

Once the new flush valve seal is installed, you can reattach the water supply to the toilet. Turn on the main water supply valve to the house and flush the toilet to check for leaks. If there are no leaks, you’re done!

Replacing the flush valve seal on an American Standard toilet is a relatively simple DIY project that can be completed in about 30 minutes. By following these steps, you can save yourself time and money by doing the job yourself.

Here are some additional tips for replacing the flush valve seal on an American Standard toilet:

  • If the old flush valve seal is stuck, you can try using penetrating oil to loosen it. Apply the oil to the seal and let it sit for a few minutes before trying to remove it.
  • Be careful not to damage the toilet bowl when removing the old flush valve seal.
  • Make sure that the new flush valve seal is installed tightly. If the seal is not installed tightly, it may leak.
  • Flush the toilet several times after replacing the flush valve seal to make sure that there are no leaks.

3. Remove the old flush valve seal

To remove the old flush valve seal, you will need an adjustable wrench.

1. Locate the flush valve. The flush valve is located on the bottom of the toilet bowl, near the back. It is a cylindrical-shaped piece of metal with a handle on top.
2. Loosen the nuts that secure the flush valve to the toilet bowl. The nuts are located on the bottom of the flush valve, near the center. Use the adjustable wrench to loosen the nuts until they are just loose enough to turn the flush valve.
3. Pull the flush valve out of the toilet bowl. Grasp the handle of the flush valve and pull it straight up and out of the toilet bowl.
4. Remove the old flush valve seal from the toilet bowl. The old flush valve seal is a rubber gasket that is located between the flush valve and the toilet bowl. It is a small, round piece of rubber that is about 1 inch in diameter. Use your fingers to pry the old flush valve seal out of the toilet bowl.

4. Install the new flush valve seal

To install the new flush valve seal, you will need a new flush valve seal, a small amount of penetrating oil, and a pair of pliers.

1. Apply a small amount of penetrating oil to the threads of the new flush valve seal. This will help to prevent the seal from sticking to the toilet bowl.
2. Insert the new flush valve seal into the toilet bowl. The new flush valve seal should fit snugly into the toilet bowl. If it does not, use your fingers to push it in until it is seated properly.
3. Secure the new flush valve to the toilet bowl with the nuts. The nuts are located on the bottom of the flush valve, near the center. Use the pliers to tighten the nuts until they are snug against the flush valve.
