Instruction on Installing a Toilet Waste Pipe
- 1). Mark on the toilet floor the location where the toilet flange hole needs to be cut out. Refer to the toilet manual regarding the required direction from the back wall, and side wall--if it is in close proximity. Place the flange on the mark, and circle with a pencil on the floor around the base.
- 2). Drill out the circle with a 1/2-inch wood drill bit, and push the flange into the hole so that the lip rests on the bathroom floor.
- 3). Apply ABS glue to the inside bottom end of the flange. Glue also the outside male end of the 90-degree elbow joint. Push the elbow joint up into the flange, and hold for 30 seconds.
- 4). Glue the inside female end of the elbow joint, and the end of a new piece of sewer pipe. Push the pipe into the elbow joint, and hold for 30 seconds. Glue couplings and new pipe as needed, until the new toilet sewer pipe reaches the main sewer line.
- 5). Mark the main sewer pipe where the new toilet sewer pipe will connect into it--use a felt tip pen. Using a hacksaw, cut through the pipe at the mark. Remove any burrs with a tradesman's knife, and wipe both sides of the cut with a damp rag.
- 6). Glue both sides of the cut, and the inside of the connecting coupling. Push the coupling between the two cuts. Make sure the coupling's spout is located so that it reaches the new toilet sewer pipe, and hold in place for 30 seconds.
- 7). Glue the inside of the coupling's spout, and the end of the new toilet sewer pipe. Push the pipe into the spout, and hold for 30 seconds.
- 8). Attach the flange lip to the bathroom floor with 1 5/8-inch galvalized screws. The toilet can now be installed over the flange.
