  3. 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.
  4. 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.
  5. 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.
