To remove a toilet flange, you will need a few tools, including a flathead screwdriver, a hacksaw, and a putty knife. First, turn off the water supply to the toilet and flush the toilet to empty the tank and bowl. Then, disconnect the water supply line from the toilet and remove the nuts that hold the toilet to the floor. Once the toilet is loose, carefully lift it up and off of the flange. Be careful not to damage the flange or the floor. Next, use the flathead screwdriver to pry up the old wax ring from around the base of the flange. Once the wax ring is removed, you can use the hacksaw to cut through the bolts that hold the flange to the floor. Finally, use the putty knife to pry up the flange and remove it from the floor.
Removing a toilet flange is a relatively simple task that can be completed in a few minutes. However, it is important to take your time and be careful not to damage the flange or the floor. If you are not comfortable removing the flange yourself, you can call a plumber to do it for you.
