How To Replace A Toilet Wax Seal OR Rubber Toilet Seal On A Toilet Flange To STOP Toilet Leaks!


A leaking toilet can cause a lot of frustration and potential water damage to your home. One common reason for toilet leaks is a faulty wax seal or rubber seal on the toilet flange. These seals are responsible for keeping the connection between the toilet bowl and the floor tight and watertight. If you notice water pooling around the base of your toilet or a foul odor coming from the bathroom, it is likely time to replace the seal.

Before you begin the process of replacing the seal, make sure to gather all the necessary tools and materials. You will need a putty knife, a wrench or pliers, a new wax seal or rubber seal, and possibly a new wax ring if it is damaged.


The first step is to turn off the water supply to the toilet. Locate the shut-off valve, usually located near the base of the toilet on the wall, and turn it clockwise to shut off the water flow.

Next, you will need to empty the tank and bowl. Flush the toilet to remove as much water as possible from the tank and bowl. Use a sponge or towel to soak up any remaining water.

Once the toilet is empty, it is time to disconnect it from the floor. Use a wrench or pliers to loosen and remove the nuts on the bolts at the base of the toilet. Carefully lift the toilet straight up and set it aside. Be cautious as toilets can be heavy.


With the toilet removed, you will be able to see the wax seal or rubber seal on the toilet flange. If it is a wax seal, remove it by scraping it off with a putty knife. If it is a rubber seal, it can often be removed by simply pulling it off.

Before installing the new seal, it is important to inspect the toilet flange for any damage. If the flange is cracked or broken, it will need to be replaced. If it is in good condition, proceed to install the new seal.

Take the new wax seal or rubber seal and place it on the toilet flange, making sure it is centered and aligned properly. Gently press down to ensure a tight seal.


Carefully lower the toilet bowl back onto the flange, lining up the bolts with the holes on the base. Apply pressure evenly to ensure a proper connection.

Finally, tighten the nuts back onto the bolts, being careful not to overtighten and crack the toilet bowl. Reconnect the water supply, turn it back on, and flush the toilet to check for any leaks.

By following these steps and replacing the faulty seal on your toilet flange, you can eliminate leaks and keep your bathroom dry and odor-free. Remember to inspect the seal regularly and replace it as needed to prevent future leaks and costly damage.
