Screw the toilet flange to the Floor
Now that you have gathered all the materials, tools, and equipment needed to install the flange properly, you can now proceed with the installation process. Follow the steps below to replace old toilet flange with a new one:
- The first thing you need to do is use a putty knife to remove the wax from the bottom of your toilet.
- After that, you will remove the old flange. Removing the old flange from the drain pipe may be pretty tricky because it has been glued to the drain pipe. Ensure that you remove the old flange carefully so you don’t damage the drainpipe.
- Clean the surfaces of the drain pipe and the new flange. After cleaning the surfaces, you will apply the PVC Primer and glue to the cleaned surfaces.
- Then insert the toilet flange into the drainpipe until the flange sits on the finished surface or the sub-floor. If the flange sits on the sub-floor, you will have to put the toilet flange spacer and use the silicone caulk to cover the bottom of the spacer.
- If the closet flange sits directly on a wooden floor, you will screw the flange or/and flange spacer into the floor with the recommended screws.
- If the flange or flange spacer is sitting on a concrete floor or a tiled floor, you will screw the flange/flange spacer to the existing holes using the Tapcon screws or any other screws. If there are no existing holes, you will drill new holes using your drill. It would be best to be careful when using the drill to avoiddamaging the drainpipe.
- Once you have screwed the flange to the floor, you will put the wax ring and attach your toilet to the flange.
