What Toilet Problems Are Created Due to Bad Wax Rings?

If you suspect your wax rings have gone bad, don’t just replace them. You can ensure that your wax rings are bad by checking for a few symptoms and then replacing them.

This will save you the cost of replacing the wax rings. Along with that, the problem will also be much more clear.

I’ve jotted down all the possible symptoms of a bad wax ring. Give it a good read.

  • Water leaks in your toilet. Wax rings are supposed to create a water-tight seal between your toilet and the sewer it connects to. If there’s any leakage in your toilet, it’s most likely due to a bad wax ring.

    The most common sighting of water leaks is water foaming around the base of the toilet. 

    Furthermore, along with the water, the bad smell of the sewer gas can also surround the toilet atmosphere. Not fixing the water leak quickly can also cause mold to grow around your toilet.
  • Bad smell. While the wax rings don’t have a distinct smell, they can surely eliminate the sewer smell by going bad. This applies to all the toilet seals out there, such as sponge gaskets, wax rings, and rubber seals

    The gas trapped inside the sewage can escape due to bad wax rings that have lost the sealing quality. Exposure to high levels of sewage is really harmful.
  • Your toilet is not sturdy. As mentioned before, wax rings work by sealing the toilet. But there’s more to it, as these rings are also responsible for providing a sturdy base for the toilet.

If you find your toilet being wobbly, reseat the toilet. If the toilet is still wobbly after reseating it, the wax ring might be uneven/potentially gone bad.

    One thorough flush should clear out the whole tank. To remove any remaining water, use a sponge.
  • After that, detach the toilet by using a ⅜ inch wrench to take out the compression nuts. After loosening up the nuts, pull the toilet to detach it. If the toilet is caulked to the floor, remove the caulking with a utility knife.
  • Then, move the toilet aside. You can move the tank first and then the remaining part of the toilet. Use lumber blocks to hold the toilet drain off the floor.

  • Afterward, remove the existing wax ring. Scrape off the old wax seal at the base of the toilet with a putty knife.
  • Next, attach the new wax ring. Make sure the wax ring is sitting in the center of the toilet flange.
  • After that, reinstall the toilet. While reinstalling it, make sure to place the toilet as levelly as possible on the newly installed wax ring. This will create a sturdy base for the toilet.
  • Then, use the wrench to bolt compression nuts and move the toilet back into place.
  • Finally, use caulk to seal the toilet with the ground and attach the tank. Turn on the water supply again and wait until the tank is full of water. Now, the bad smell and leaking problem should be gone!
