Step-by-Step Guide to Remove & Replace a Leaking Toilet Flange

Now that you have a clear understanding of the toilet flange and its signs of leaking, let's walk through the process of removing and replacing it step-by-step.

Step 1: Prepare the Area

Turn off the water supply to the toilet and flush to empty the tank. Remove any items around the toilet to create a safe working environment.

Step 2: Disconnect the Toilet

Use an adjustable wrench to disconnect the water supply line from the toilet tank. Next, remove the nuts securing the toilet to the flange using your wrench or screwdriver. Carefully lift the toilet straight up and set it aside on a protective surface.

Step 3: Remove the Old Flange

Inspect the old flange. If it's damaged or corroded, use a pry bar to break it free from the floor. If the flange is glued, use a utility knife to cut through the adhesive. Remove any remaining screws or bolts as necessary.

Step 4: Clean the Area

Once the old flange is removed, clean the area thoroughly. Remove old wax from the previous seal using a utility knife and ensure the subfloor is intact.

Step 5: Install the New Flange

Position the new flange over the drain pipe. Ensure it is level and flush with the floor. Secure it using screws or adhesive as necessary.

Step 6: Install the Wax Ring

Place a new wax ring on top of the flange. Ensure it is centered and properly seated.

Step 7: Reattach the Toilet

Carefully lower the toilet onto the wax ring and flange. Press down evenly to ensure a proper seal. Secure it in place with toilet bolts.

Step 8: Reconnect the Water Supply

Reconnect the water supply line to the toilet tank. Turn on the water supply and flush to check for leaks.

Step 9: Caulking (Optional)

For additional sealing, you can apply caulk around the base of the toilet.
