DIY sewage in the apartment. What to look for and how to carry out construction work

Overhaul is never complete without replacing the sewer system. But the prices for repair specialists are forced to transfer these works for the next year or to get down to business on their own. Without preliminary experience, it will be very difficult to install sewer pipes with your own hands, but the tips and recommendations from our article will help to perform their installation at a height.

Beginning of work

One of the main components of any apartment is sewage. This system in the room is non -pressure and performs the function of removing common wastewater. They should be delivered from the apartment to the common riser of the house. That is, to complete its immediate tasks, the sewage should be under a certain inclination. In this case, it is necessary that the descent angle allows you to set the direction of the wastewater and allow them to advance quickly.

You need to start work with the layout of the sewer system. If the owners of the apartment simply arrange a major overhaul with the replacement of old pipes, then the task is to become much easier. If you entered a new room, and the sewage system is absent in it, then it will be necessary to deal with the question of how the sewage system is arranged in an apartment building. In this matter, neighbors or housing and communal services can help.

What actions need to be done at the planning stage? First of all, you need to decide on the future places of the location of plumbing and other important details of the bathroom. Secondly, it is necessary to calculate the correct angle of installation of sewer pipes. Thirdly, you need to choose the right materials for repair work.

The choice of materials

High -quality sewage wiring in the apartment with your own hands largely depends on the correctly selected materials for work. Of course, pipes will be the most important detail. Previously, this material had a very narrow choice. The most popular sewer pipes were considered cast iron, but in our advanced century a lot of a new variety appeared. Now most often in their apartments, owners use plastic pipes:

Poenile -olds - their main advantage is low price. But we do not recommend stopping on this option, because in addition to the cost of other advantages, the pipes do not. They are very susceptible to deformation, have low heat resistance and are sealrated quite unreliable. Only alternative manufacturers continue to supply poethylene pipes on sale. But to make a sewage repair repair that will last a couple of days is not profitable and stupid.
PVC is the average cost. The hydraulic resistance of these pipes is considered the smallest. Between themselves, they can be connected using dichloroethane glue. But there are drawbacks. First of all, limited heat resistance (up to 80C), not high strength and resistance to chemicals. PVC pipes are cleaned exclusively using a plunger or ultrasonic emitter.
Polyizopropylene are one of the most expensive pipes at the moment. It does not have such a smooth surface as in PVC, but otherwise it is ahead of other types of sewer pipes. It withstands temperatures in over 130C, so strong and persistent that they can withstand mechanical and chemical cleaning.

In addition to pipes, it is necessary to purchase material for their connection. The best option will be silicone lubrication. It was created for the installation of sewer pipes. Using silicone grease, the owner will be able to finish the repair work as soon as possible, and also reduce the hydraulic resistance. If your choice fell on polypropylene pipes, then you need to consider that special cuffs are needed for their installation. If they are unsuccessfully joined, then the pipe is deformed and will create voltage in this part of the sewage system due to sharp temperature transitions. But with the help of silicone lubrication, this can be avoided.

Calculation of the angle of inclination

As has already been foreseen, the selection of the angle of inclination for the sewer pipe is a very responsible step. If the slope turns out to be too small, the wastewater will not be able to be delivered to the right place, and if it is too large, then the water will go quickly, and the pollution is attached to the walls of the pipes, which will create constant blockages. Therefore, there are clearly defined limits of values. A minimum for a pipe with a diameter of 5 cm will become an angle of inclination of 3 cm/m, 11cm 2 cm/m, 16 cm 0.8 cm/m, 20 cm 0.7 cm/m. The maximum does not depend on the diameter of the pipe and is 15 cm/m (exceptions will be options with a length of more than one and a half meters). A right angle for the sewage system becomes possible with its vertical location.

It is quite difficult to withstand the angle of inclination in the apartment with your own hands, since it is necessary to take into account not only the parameters, but also the features of the device of sewer pipes. Therefore, at this stage of work, it is better to take the help of a specialist.

Scheme of the sewer system

With the usual replacement of the sewer with a more new one, the stage with the scheme disappears by itself, since it is enough to remember the location and mount the same principle. But in cases where there were problems with old pipes or in a new room at all, the quality of this item will become the main key to well done work.

The connection scheme of plumbing devices should include the following points:

rooms in which work is supposed to be performed;
in each of these rooms, we indicate the location of the parts of the sewer system (it is necessary to specify the dimensions of the elements and their distance from the walls). Moreover, details are not only a bathroom, but also complete wiring;
the location of all fittings and official elements;
the place where the central sewer riser is located.

After, it is advisable to give the compiled scheme to specialists to verify its correctness (the cost of such a service will not be too high).

Dismantling of old pipes

After all previously performed actions, you can proceed to directly the repair work itself. If the house has previously had a sewer system, then the first thing you will need to get rid of it, or to dismantle old pipes. At this stage, relations with neighbors will play an important role. To do the dismantling independently, we alternately perform the following points:

We choose in the walls the places in which the pipes are embedded. You can choose another way to solve this problem, but the main thing is that the pipeline is released from the walls.
All the bathroom devices located in rooms such as the kitchen and the bath are eliminated, and we free the rooms themselves from unnecessary things.
In places where new parts will be installed, we draw on the surfaces the contours with a pencil.
We agree with our neighbors to turn off the water for a certain time.
We block the riser on the floor.
It will also be required to remove the toilet and the flush barrel in the toilet.

Disconnect the sewage wiring from the riser. In order to perform this process, it will be necessary to cut the pipe in two places, the distance between them should be in the range of 12-15 cm. After we drive the wedge into the cut, which is located further from the riser. The latest actions need to disconnect the entire pipe and break the cuts.
We drill a hole in the previously pointed contour (or you can squeeze the contour with a chisel and a hammer) and removed the remainder of the pipe. At the same time, it must be remembered that cast iron is quite fragile, and therefore you need to perform actions extremely neatly.
We proceed to the cleansing of the internal allotment of the divorce pipe and toilet. Next, we plug them tightly with unnecessary rags.
We open the riser and serve the water, which we inform our neighbors about. The main thing is to warn them after what time you will have to start work again.
Next, we are disassembled by the pipeline, starting from the far end.

Installation work

After eliminating old pipes, we go to the installation. There are two types: draft and finishing. Today we will consider the second option in which installation is carried out starting work from the riser. The main rule of this type of installation: the size is not adjusted to the next, but the previous sewer pipe. If you do, on the contrary, the wiring simply will not hold.

Instructions for the installation of sewage in the apartment are as follows:

1. First of all, it is necessary to make a transition from a cast -iron pipe to plastic. To do this, you need to install a special cuff. It is placed in the divert of the riser.

2. Having fixed the cuff in the 1st section of the sewer pipe, we check whether the mounting pipe is fixed.

3. We go to pruning. This must be done carefully, observing the size.

4. Next, clean the resulting cut and remove the chamfers.

5. We finish the installation using sealant;

6. The remaining pipeline is collected behind the sections of the pipes using the same principle.

7. To install the riser, you need to fit exactly the size of the toilet pipe, and then put it on the sealant, and install the toilet back.

8. As soon as the sealant completely freezes, it is necessary to conduct a check for the leakage of the sewage system, make it soundproofing and install the water supply.

Many are interested in whether the water supply is an important part in the installation of sewage system. Without it, the pipes, of course, will work, but its installation is necessary. The purpose of the water plant in the sewer system is the prevention of unpleasant odors. Therefore, if you do not have a desire to hear the stink of the sewer, do not stir up on this part.

Note to install

Observing all the installation of pipes, the owner of the apartment will be able to independently install the sewer system. But sometimes these repair work are becoming too hard for execution. Therefore, we found useful tips for the installation of sewage in an apartment from real professionals:

be sure to put on protective clothes before starting the installation of pipes;
so that there are no problems with installing the cuff, grease it with liquid soap. Then the detail is much easier to enter the cut of the pipes;
to be more confident in the reliability of the system, before the start of installation, grease the ends of the pipe with glycerin grease;
if you do not live on the top floor, then it is not recommended to replace the riser;
the trumpet connection of the pipes is carried out using rubber seals.

Sealing compounds

To seal sealing the following actions:

we select the correct sealant. To mount sewer pipes, you need to purchase neutral, silicone, as well as polyurethane;
it is necessary to process each of the plastic gaskets. Do not apply sealant with a thick layer, this will only worsen the quality of work. Also, do not forget to install rubber gaskets in couplings;
next, you need to apply a sealant to the surface of the mounting pipe and on the outer wall of the mating sewer pipe;
we fix the pipes in couplings;
we wrap the resulting joints with cling film and level the sealant, not much pressing, using any tool (spatula, brush, roller, etc.);
the film should remain at the joints until the sealant is completely solidified.

After complete sealing of the sewage system, you can proceed to its use. But first you need to check the installed system for the leak.

Checking for the leakage of the sewer system

Checking for the leak is mandatory for performing the stage. If you skip this process in the future, the sewer can simply break through and flood all the neighbors from below. To check on the presence of leaks, fill the full bath. Next, you need to open all the existing cranes in the room and remove the cork from the bath. If everything has flowed out and the puddle does not appear, you can sleep peacefully, the sewage system is made at the highest level.

Conclusion

Adhering to the rules for the installation of pipes and the advice described in the article, you can easily and freely make a sewer in the apartment with your own hands. The main thing is to perform all the processes for conscience and remember that the comfort of housing will depend on the quality of the completed system.
