How to Install a Fluidmaster Toilet Seal

Typically, toilets are sealed to the floor and drain by means of a wax ring. Wax rings have been used for decades but they come with some disadvantages. Over time that seal can break if the toilet shifts for any reason.

The modern solution is a rubber or foam seal that can withstand potential toilet shifting or repeated removal. These modern seals also allow toilet removal and reinstallation without having to scrape off the old messy wax seal saving time and mess!

Fluidmaster Toilet Seal Instructions

Installing a Fluidmaster toilet seal is a relatively simple task that can save you money on expensive repairs in the future. Here are detailed instructions on how to install a Fluidmaster toilet seal:

  1. Turn off the water supply to the toilet. This is an important step to prevent any water from entering the toilet while you are working on it. The water supply valve is typically located behind the toilet or under the sink. It may also be located in a utility room or basement. Turn the valve clockwise to shut off the water.
  2. Flush the toilet to remove as much water as possible from the tank. This will make it easier to remove the old toilet seal and install the new one.
  3. Remove the tank lid and set it aside.
  4. Remove the remaining water inside the tank using a sponge or rag.
  5. Locate the old toilet seal. The toilet seal is typically a brown wax ring that sits between the bottom of the toilet tank and the top of the toilet bowl. It is usually found around the base of the toilet, where the tank and bowl meet. Sometimes when removing the toilet all or a portion of the wax ring might get stuck on the bottom of the toilet.
  6. Wear gloves
  7. Scrape off the wax ring using a putty knife or other flat tool. Gently pry or scrape the old toilet seal off the toilet bowl. Be careful not to damage the toilet bowl while removing the seal. The seal may be stuck in place due to age or debris, so use caution when prying it off.
  8. Clean the area where the new seal will be installed. Use a small brush or toothbrush to remove any dirt or debris that may have accumulated over time. This will help ensure that the new seal sits evenly on the bowl and seals properly.
  9. Unpack the Fluidmaster toilet seal and carefully place it on the toilet bowl base (if it is the type that sticks to toilet). Some types are mounted first on the floor and the toilet is then place on it to form the seal.) Make sure it is aligned correctly and seated evenly. The fluidmaster seal should sit securely on the bowl without any gaps or spaces.
  10. Set the toilet. The mounting screws should be in place (pointing up from the toilet flange around the drain) With the toilet in place, add the nuts and washers to the screws and tighten the screws evenly and gradually to secure the toilet base to the toilet flange in the floor. Be careful NOT to over tighten the nuts as the toilet base could crack or break.
  11. Replace the tank lid
  12. Turn the water supply back on. Carefully place the tank lid back on the tank, making sure it is aligned correctly. Then, turn the water supply valve back on by turning it counterclockwise.
  13. Flush the toilet a few times to ensure that the new seal is working properly and that there are no leaks. Keep an eye on the seal and the tank to make sure everything is working as it should.
  14. Check the seal periodically to make sure it is still seated correctly and not leaking. Over time, the seal may loosen or shift, causing it to leak. If you notice any problems, you may need to adjust the seal or replace it again. Regular maintenance and replacement of the toilet seal can help prevent costly repairs down the line.

That’s it! With a little bit of effort and a Fluidmaster toilet seal, you can easily fix any leaks or other issues with your toilet.
