WOODEN SUB-FLOORING REPAIR TOILET – PART 3 OF 3
On an inside doing flange, take an electric drill with the largest drill bit and drill holes around the ABS coupling of the flange. Then use the mini hacksaw and cut around the coupling. Unscrew the deck screws holding the flange to the sub-flooring, the metal ring can now be removed.
Next, take the mini hacksaw and cut the ABS coupling to the sewer inlet. Several cuts may need to be made. Now, wedge the plyhead screwdriver between the ABS coupling and the sewer inlet, twisting break the glued seal. Again, with some work the coupling should be able to be removed.
Now that both flange removal scenarios are removed, the next task is to replace the damage wooden-sub-flooring. Mark with the carpenter’s square or straight edge the area of floor that needs to be cut out. Make the area large enough so the floor joist that’s inside of the flange is used for support. Cut out the bad sub-flooring using a power saw such sub-flooring thickness usually ¾ of an inch. Be careful not to cut the floor joist below, when the sub-flooring is removed supporting scratch will need to be installed to get the replacement floor more stability. They must be cut to fit and be mounted between the floor joist and high enough to support the replacement floor.
With the new support straps in place screw the main of the decks screws and make sure they are secured. Cut and install a new piece of sub-flooring that fits into the desired space where they’re hold ready and position for the sewer inlet. Screw down the new piece of replacement sub-flooring, secure it to the stretch and structural beams that we’re just installed, using our deck screws so that the floor is moving or squeak.
Now that the sub-flooring has been replaced, glue the new flange with the sewer inlet with the ABS glue. When the flange is not placed properly with the mounting channels even at a nine and three o’clock positions, screw down the flange mounting it tightly to the sub-flooring. Replace any hard flooring to the edge of the sewer inlet or carpet to the base of the toilet. Once the flooring is put back, insert the toilet mounting bolt into the channels of the flange; securing them up with their plastic washers.
Finally, place the wax ring over the flange and the toilet is ready to be installed.
