Over time, the PVC toilet flange can become damaged or worn out. This can cause leaks, which can lead to water damage and mold growth. If you suspect that your PVC toilet flange is damaged, it is important to replace it as soon as possible.

2. Remove the toilet from the flange. There are two ways to remove a toilet from a flange:

  • Using a flange nut wrench. If your toilet has a flange nut wrench, you can use it to loosen the nuts that hold the toilet to the flange. Once the nuts are loose, you can lift the toilet off of the flange.
  • Using a hacksaw. If you do not have a flange nut wrench, you can use a hacksaw to cut through the bolts that hold the toilet to the flange. Once the bolts are cut, you can lift the toilet off of the flange.

5. Apply a new wax ring. Once the flange is installed, you will need to apply a new wax ring to the bottom of the toilet. This will help to create a seal between the toilet and the flange.

7. Turn on the water supply to the toilet. Once the toilet is reinstalled, you can turn on the water supply to the toilet. This will allow water to flow into the toilet bowl.

8. Check for leaks. After you have turned on the water supply to the toilet, you should check for leaks. To do this, you can look under the toilet for any signs of water. If you see any leaks, you will need to tighten the nuts on the bolts until the leaks stop.

Replacing a PVC toilet flange is a relatively simple task that can be completed in a matter of minutes. By following the steps carefully, you can ensure that the new flange is installed correctly and that your toilet is functioning properly.
