If you want to know how the replacement of the sewer riser is going on, then our article will definitely help you with this. This procedure must be carried out if the cast -iron pipe has already served you a couple of decades and no longer cope with its «duties». This case should not be postponed.
Replacement of the sewer riser — where to start?
Installation of sewage in the apartment — video
In general, the replacement of the sewage system is a voluminous and problematic matter, not everyone decides to carry out work on their own. This, firstly, can hit both material and morally. But still — nothing is impossible. Therefore, our article today is devoted to how to replace the sewage system with your own hands — you will find a video with a description on our resource. What is needed for this, and how do installation work undergoes?
You should start work with the warning of your neighbors about the upcoming repair, so that no one at that moment thinks of draining the water, which will ruin all your efforts. And all because you will have to turn off the water in any case for some period.
Tip: choose modern plastic materials if you want everything to work in the future just “excellent”. Their main advantage during operation is that over time they are not exhausted, do not rust, weigh less than any other materials. True, one minus is still — since their thickness is smaller, you will always have to hear the moment when the neighbors are drained from above and below.
We carry out dismantling work
On the video — changing the sewage apartment wiring
If you see that it is impossible to cope with the problem (leakage of water, for example), then it’s time to change the sewer riser. That is why it is necessary to first dismantle the one that is currently installed in our apartment. In order to carry out everything correctly, first you need to break through the pipe on each floor in the floor in the ceiling. Starting from above, pull the pipes into a piece. But this is when replacing the whole riser.
Dismantling directly in your apartment, you need to follow the following rules:
The pipe needs to be cut using either a pipeline or a grinder. In this case, it is impossible to make incisions parallel.
Do not forget that the pipe cannot be cut to the end, because under its own weight it can just collapse down.
The cut ring should be extracted by scoring a wedge into the resulting incisions.
With the help of a screwdriver or a chisel, you need to break a piece of sewer as accurately as possible, carefully making sure that it does not fall, if there are any fragments, they need to be knitted with a hammer.
Next, you should continue the trim in the upper part of the riser. The upper piece must be cut off to the height that was made according to calculations. If you install plastic pipes, you should leave such a piece in size so that it goes out to the length that will be equal to the length of the shaped parts.
So, we finished directly with the dismantling procedure, therefore, we can proceed to the process of installing new sewer pipes. As you could already notice, there is little easy light, and therefore you have to try a lot to make everything go smoothly and competently, otherwise you can break the work of the entire sewer system of your house.
How to change the sewer riser — tools, materials and work plan
Naturally, in the process of such work, you cannot do without specific material and tools, and therefore you must acquire the following:
Tower with a challenge or crosspiece made of plastic
Cuffs for compounds of plastic and cast -iron pipes
Plastic (or any other) pipe
Pipe branch
Fastening to the riser
Hammer
Perforator
Pencil for marking
Weight or level
Technology and stages of work:
If you want to know how the sewage riser is being replaced, you should definitely remember what actions and in what sequence you should carry out.
First you need to install a tee (cross), for which a gasket or cuff should be inserted into the bell.
The end of the tees is necessarily lubricated with liquid soap — this will make installation easier and faster.
Cut the plastic pipe into the length you need by processing the end with the help of the “skins”, which will ensure the best docking in the process.
In order to correctly determine the desired size of the pipes, you should insert the pipe into it to the stop, and the design that came out, we need to further insert into the upper part of the old sewer.
Recommendation: If you change cast -iron sewers to a plastic analogue, you must use a pipe 0 instead of a familiar sliding coupling — this is much more reliable.
Then we will need to install fasteners, for which we place and fix the clamps on the walls.
It is best if you carry out an approximate assembly in advance, which will help you directly in the implementation of finish work.
We carry out the connection of the pipes: lowering a piece of the pipe into the hole, hold it not only with a clamp, but also with your hands, this will help you avoid serious breakdown. Next, clamp the remaining clamps for fasteners.
Our last action is a verification of the operability of the sewage system, for which you need to let water out of the riser several times.
