How to Replace a Toilet Drain Pipe Part 1 How to Replace a Toilet Drain Pipe Part 1
Replacing the toilet drain pipe in your bathroom can be a bit of a tricky job. To correctly fit the pipe, you will have to go into the wall behind the toilet or even under the ground to find the end of the drain. This can be a rather nasty job, and may people prefer to call their plumbers rather than risk getting dirty, wet or being exposed to bugs and vermin. If you wish to perform this task for yourself, then you will need some basic home improvement tools. In Part 1 of this guide, you will learn how to remove the toilet and the toilet flange, cut away the wall and floor surrounding the toilet drain and then take up the closet bend.
Step 1 - Turn Off the Water
Before you can proceed with taking off the toilet, you will need to turn off your water supply. As you will not only be removing the toilet, but also taking up the drain, you should turn off the water supply at the mains. Once the mains has been turned off, run the water through the system once or twice by flushing the pan. This will empty the toilet and ensure that there is a limited amount of water left in the toilet system.
Step 2 - Remove the Toilet
The next step is to take off the toilet. You will have to start by removing the bolts which hold it to the floor. Use your wrench to loosen the nut, and then draw out the bolt part. Place these in a safe area, as you will need to put them back into place once you have finished. Make sure that you have taken off all of the bolts, and then unscrew the pipe from the back of the toilet. Lift up the toilet as one piece, and place it in a secure location.
Step 3 - Remove the Flange
The next step is the toilet flange. This should be exposed when you lift up the toilet. The flange will be held to the floor with a number of deck screws. Remove these with a screwdriver, and then take off the flange. You may find that you have an offset flange, which will cause complications when you come to fitting the new toilet drain pipe.
Step 4 - Cut Down the Flooring
The next step is to cut away the flooring around the drain pipe. You will need to take up as little flooring as you can mange. Use a saw to cut away the parts of the floor that you need to remove, until you can clearly see the underneath of the floor, and remove as much of the nearby wall as you like.
Step 5 - Remove the Closet Bend
Reach inside the pipe to feel a pipe with a curved bend on the end. This is the closet bend. You may be able to unscrew the nuts to release the bend, or you may need to cut the pipe to sever the curve and remove it.
