Step-by-Step Guide to Replacing Your RV Toilet Seal

Step 1: Gather Your Tools and Materials

Before you begin, make sure you have everything you’ll need:

Step 2: Turn Off the Water Supply

Start by turning off the water supply to your RV toilet. You don’t want any water flowing while you’re working on the toilet. Close the water valve and flush the toilet to empty the tank.

Step 3: Remove the Toilet

To replace the seal, you’ll need to remove the toilet from the floor. Use your wrench set to loosen and remove the bolts holding the toilet in place. Depending on the model of your RV toilet, you may need to disconnect the water supply line as well. Gently lift the toilet off the flange and set it aside.

Step 4: Clean the Area

Now that you’ve removed the toilet, it’s time to clean the area around the flange. Use Lysol Power Bathroom Cleaner to remove any residue, grime, or mold around the base. A clean surface is essential for ensuring a proper seal with the new toilet seal.

Step 5: Remove the Old Seal

Carefully remove the old rubber seal from the toilet base. It may be stuck in place with old adhesive or sealant. You may need to use a utility knife to gently pry it off. Be sure to remove all remnants of the old seal to prevent any leaks when installing the new one.

Step 6: Install the New Toilet Seal

Once the old seal is removed, it’s time to install the new one. If you’re using the Thetford RV Toilet Seal Kit, simply follow the included instructions to place the new seal into position. Ensure that the seal is aligned properly and is seated firmly in place.

Step 7: Apply Sealant

To ensure a tight seal, apply Dicor Butyl Rubber Sealant Tape around the base of the toilet flange. This will help prevent any leaks and create a waterproof barrier between the toilet and the floor. Press the toilet back into position, making sure the seal stays in place.

Step 8: Reinstall the Toilet

Once the new seal and sealant are in place, carefully lower the toilet back onto the flange. Tighten the bolts using your wrench set to secure the toilet to the floor. Be sure not to overtighten, as this could crack the toilet or flange.

Step 9: Reconnect the Water Supply

Reconnect the water supply line to the toilet and turn the water valve back on. Test the toilet by flushing it a few times to make sure everything is working correctly and there are no leaks around the base.


And that’s it! Replacing your RV toilet seal is a straightforward task that can make a huge difference in preventing leaks and keeping your bathroom dry. With the right tools and products, you’ll have your toilet sealed up tight and ready for your next adventure. Happy RVing!
