How to Change a Toilet Flange

Your toilet flange is a critical part of your plumbing system. It’s the metal ring that connects your toilet to the drainpipe, and it helps to create a seal that prevents leaks. Over time, the flange can become damaged or worn out, and it will need to be replaced.

Changing a toilet flange is a relatively simple DIY project, but it’s important to do it correctly to avoid leaks. In this article, we’ll walk you through the steps of how to change a toilet flange, so you can get the job done quickly and easily.

Tools and Materials

  • Replacement toilet flange
  • Penetrating oil
  • Adjustable wrench
  • Pliers
  • Tape measure
  • Level
  • Bucket
  • Plumber’s putty
  • Silicone sealant

Steps

1. Turn off the water supply to the toilet. This is usually located behind the toilet, near the floor. Turn the valve clockwise until it’s completely closed.
2. Remove the toilet seat. There are usually two bolts located on the underside of the toilet seat. Use a wrench to loosen and remove the bolts.
3. Disconnect the water supply line. The water supply line is a flexible hose that connects the toilet to the shutoff valve. Use a pair of pliers to disconnect the hose from the valve.
4. Remove the old toilet flange. The toilet flange is a metal ring that is bolted to the floor. Use an adjustable wrench to loosen the bolts that secure the flange to the floor. Once the bolts are loose, you can lift the flange up and out of the toilet bowl.
5. Apply penetrating oil to the bolts on the new flange. This will help to loosen the bolts when you’re reinstalling the flange.
6. Position the new flange over the drainpipe. Make sure that the flange is centered over the drainpipe and that the bolts are aligned with the holes in the flange.
7. Secure the flange to the floor with the bolts. Tighten the bolts until they’re snug, but don’t overtighten them.
8. Reconnect the water supply line. Insert the end of the water supply line into the valve and tighten the connection with a wrench.
9. Turn on the water supply to the toilet. Make sure that there are no leaks at the flange or the water supply line.
10. Replace the toilet seat. Carefully lower the toilet seat onto the toilet bowl and secure it with the bolts.

That’s it! You’ve now successfully changed your toilet flange.

How to Change a Toilet Flange

A toilet flange is a metal or plastic ring that connects the toilet to the sewer line. It is important to keep the toilet flange in good condition, as a leak can cause damage to your home and plumbing. If you notice that your toilet is leaking, or if the wax ring around the toilet is damaged, you will need to replace the toilet flange.

This guide will show you how to replace a toilet flange. It is a relatively simple task, but it is important to follow the steps carefully to avoid damaging your toilet or sewer line.

Tools and Materials

  • Replacement toilet flange
  • Pliers
  • Tape measure
  • Combination or socket wrench
  • Penetrating oil
  • New wax ring
  • Bucket
  • Shop towels
  • Gloves

Step 1: Turn off the Water Supply

The first step is to turn off the water supply to the toilet. This is usually located at the back of the toilet, near the floor. There will be a shut-off valve that you can turn with a wrench. Once the water is turned off, flush the toilet to drain any remaining water.

Step 2: Remove the Old Flange

The next step is to remove the old toilet flange. There are two ways to do this:

  • If the flange is attached with bolts, you can use a wrench to loosen the bolts and remove the flange.
  • If the flange is attached with sealant, you can use a putty knife to loosen the sealant and pry the flange off.

Once the flange is removed, you will need to clean the area around the toilet bowl. Use a putty knife or scraper to remove any old sealant or wax.

Step 3: Install the New Flange

Now it is time to install the new toilet flange. The flange will come with instructions, but the basic steps are as follows:

1. Apply a bead of plumber’s putty around the edge of the flange.
2. Center the flange over the drain opening.
3. Press down on the flange to seat it in place.
4. Secure the flange with bolts or sealant.

Step 4: Apply the Wax Ring

The next step is to apply the wax ring to the toilet bowl. The wax ring is a rubber gasket that creates a seal between the toilet and the flange.

To apply the wax ring, first cut it to size. Then, place the wax ring around the bottom of the toilet bowl, so that it is centered on the drain opening.

Step 5: Attach the Toilet to the Flange

Now it is time to attach the toilet to the flange. This is done by placing the toilet over the flange and securing it with bolts.

1. Place the toilet over the flange.
2. Insert the bolts through the holes in the toilet and flange.
3. Tighten the bolts with a wrench until the toilet is secure.

Step 6: Connect the Water Supply

The final step is to connect the water supply to the toilet. This is done by attaching the supply line to the valve at the back of the toilet.

1. Turn on the water supply to the toilet.
2. Attach the supply line to the valve.
3. Tighten the connection with a wrench.
