How to Replace RV Toilet Seal

RV toilets are notorious for having leaky seals. This is because they are constantly subjected to moisture and movement. If the seal is not properly maintained, it can eventually break down and leak. A leaky toilet seal can waste water, damage the RV floor, and create a breeding ground for mold and mildew.

Replacing the RV toilet seal is a relatively simple task that can be completed in a few hours. However, it is important to follow the steps carefully to ensure that the new seal is installed correctly.

Tools and Materials

  • Replacement toilet seal
  • Silicone sealant
  • Utility knife
  • Penetrating oil
  • Rags
  • Screwdriver
  • Penetrating oil

Step 1: Prepare the Toilet

The first step is to prepare the toilet for the new seal. This involves removing the old seal and cleaning the toilet bowl.

To remove the old seal, you will need to use a utility knife to cut around the edge of the seal. Be careful not to damage the toilet bowl. Once the seal is cut, you can carefully pry it up and remove it.

Once the old seal is removed, you will need to clean the toilet bowl. This will help to ensure that the new seal will adhere properly. Use a cleaning solution and a rag to clean the toilet bowl. Be sure to rinse the bowl thoroughly.

Step 2: Apply Silicone Sealant

The next step is to apply silicone sealant around the edge of the toilet bowl. This will help to create a watertight seal.

To apply the sealant, you will need to use a caulking gun. Be sure to apply a thin layer of sealant around the edge of the toilet bowl. Do not apply too much sealant, as this could cause the seal to leak.

Step 3: Install the New Seal

Once the sealant is dry, you can install the new seal. The new seal should come with instructions on how to install it. However, the basic steps are as follows:

1. Place the new seal on the toilet bowl.
2. Press down on the seal to make sure it is properly seated.
3. Use a screwdriver to tighten the screws that hold the seal in place.

Step 4: Test the Toilet

Once the new seal is installed, you should test the toilet to make sure it is working properly. Flush the toilet and look for any leaks. If you see any leaks, you will need to re-apply the sealant or replace the seal.
