What Are the Steps for Thetford RV Toilet Removal?


Follow these easy steps to remove an RV toilet:

Make sure that you switch off any water source that is coming and going to the toilet. Either turn off your water pump or remove the water hose from the pipe valve that connects you to the city’s water supply.

To assist you with the steps in disconnecting from the water supply, it is best that you rely on the detailed manual that comes when you purchase your camper van. If there is no available manual, you can just search it up online.

Ensure that you never forget to do this step, because you will not be able to remove the toilet itself if the water is still flowing. You do not want to let the toilet water flow all over inside your camper vehicle, do you?

Double-check if your RV toilet comes with a spray attachment; it is often located at the back of the toilet. If there is one, switch off its water supply by turning the valve knob counterclockwise.

Step 2: Flush the RV toilet to release any water pressure

Make sure that you fully release any water pressure by flushing the RV toilet and the spray attachment. Stop when there’s no more water flowing out.

Step 3: Take out and deplete the water supply line

Step 4: Remove toilet bolt covers & toilet bolts

Most probably, the nuts and bolts of your RV toilet have covers. To remove them, make use of your flathead screwdriver.

Double-check all sides of the toilet — front, back, left, and right, and find any visible RV toilet bolt covers and remove them.

After removing all the bolt covers, you may take off the nuts and bolts with the help of a 0.5-inch socket wrench. For areas that you find difficult to access, make use of a 12” socket wrench extension to assist you with your task.

Technically, this step is the most tedious part of the process. When you have successfully removed the nuts and bolts, the following steps will just be a piece of cake for you.

Note: Most likely, your newly purchased RV toilet will come with a Thetford RV toilet seal replacement with nuts and bolts. However, it is better to be prepared and keep the old toilet bolts in case the new toilet doesn’t have them.

Step 6: Clean the surface of the floor flange

Using your rag, ensure that the floor flange surface is clean and clear of any trash and sealant residue.

Step 7: Put a cloth at the top of the waste hole

Although this is optional, you may want to consider putting a cloth above the waste hole. A cloth is added to lessen any smell from the black water tank below. Moreover, it helps in preventing any screws, nuts, bolts, and other tools from dropping right into the hole.
