How to Replace a RV Toilet Flange Seal: A Step-by-Step Guide

How to Replace an RV Toilet Flange Seal

RV toilets are notorious for leaking, and a common culprit is a worn or damaged flange seal. The flange seal is a rubber gasket that sits between the toilet and the drain pipe, and it helps to create a watertight seal. If the seal is damaged, water can leak out of the toilet and into the RV, causing damage to the floor and subfloor.

Replacing a flange seal is a relatively simple DIY project, but it’s important to do it correctly to avoid further damage. In this article, we’ll walk you through the steps of replacing an RV toilet flange seal, so you can get your RV back in working order in no time.

What You’ll Need

  • New flange seal
  • Replacement wax ring
  • Penetrating oil
  • Adjustable wrench
  • Pliers
  • Flathead screwdriver
  • Bucket
  • Shop towels

Steps

1. Turn off the water supply to the toilet. Locate the shut-off valve for the toilet and turn it clockwise until it is completely closed. This will prevent water from flowing into the toilet while you are working on it.
2. Remove the toilet seat. There are usually two bolts located on the underside of the toilet seat. Use a wrench to loosen these bolts and remove the seat.
3. Locate the flange. The flange is a metal ring that is attached to the floor of the RV. It is located directly underneath the toilet.
4. Apply penetrating oil to the bolts that hold the flange in place. This will help to loosen the bolts and make them easier to remove.
5. Use a wrench to loosen the bolts that hold the flange in place. Work slowly and carefully, as you don’t want to damage the flange.
6. Remove the flange. Once the bolts are loose, you can carefully lift the flange up and out of the toilet.
7. Remove the old wax ring. The wax ring is a round gasket that sits between the toilet and the flange. It is usually a dark brown or black color. Use a flathead screwdriver to carefully pry up the old wax ring and remove it.
8. Apply a new wax ring to the toilet. The new wax ring should be a light brown or tan color. Follow the instructions on the package to apply the wax ring correctly.
9. Place the new flange in the toilet. Make sure that the flange is properly aligned with the drain pipe.
10. Secure the flange in place with the bolts. Tighten the bolts until they are snug, but not too tight.
11. Turn on the water supply to the toilet. Make sure that the toilet is properly draining.
12. Replace the toilet seat. Follow the instructions in step 2 to reinstall the toilet seat.

That’s it! You have now successfully replaced the flange seal on your RV toilet.
