Pipes

In our time, many technologies have become available to ordinary citizens. In this article we will tell how to make installation of sewage pipes with your own hands. This procedure will not cause you serious difficulties if you follow all instructions.

To ensure comfortable use of all the amenities of civilization, you will have to try a little.

Theory

Installation of sewage pipes is impossible without preliminary design. Such facilities are regulated by SNiP 2.04.01-85. Gasket must be done relative to the location of plumbing and household appliances (for example, a washing machine).

Therefore, before installing the sewer pipes you should plan everything carefully.

With reference to the room, the whole system can be divided into:

Horizontal;
Vertical.

Horizontal part

Installation of sewer pipes horizontal arrangement has the following features:

Contrary to their name, they do not have a horizontal location. The fact is that there is an angle of inclination of the sewer pipe. It is necessary for the fluid to flow down the riser as a result of gravity.
The speed of movement of drains directly depends on which angle of the sewer pipe is selected. If we are talking about the value of 0.02-0.03, then the most optimal speed will be achieved, that is, about 1 meter per second.

Advice: to ensure such a value, it is necessary to make a gradient of 2-3 cm per meter of the line. For more specific information on this matter, you can refer to SNiP 2.04.01-85.

Moreover, if the element has a diameter of not more than 5 cm, then the slope is 0.03, and for large models 0.02.
If the slope of the sewer pipe is reduced, then the rate of wastewater decreases. Of course, this situation can lead to the formation of deposits. Simply put, the larger the angle, the less likely the blockage.
Each highway, located horizontally, must necessarily end with a siphon. Such a measure prevents unpleasant odors from entering the house.

This schematic photo shows how to make the connection correctly.

Fittings of certain sizes should be used in certain areas.

The instruction reads as follows:

The central stand and the toilet exit should have a diameter of 100 mm.
Sinks for the sink and bathroom - 50 mm. If they are connected separately, then 40 mm is enough.
Sink and bidet - 30 mm.

Vertical part

Usually in each house it is only one. The rest of the system is already connected to it.

Before you collect sewer pipes vertical plan, understand for yourself a few simple but very important rules:

If it is intended to withdraw a riser to the roof or attic, its opening must be partially closed (for example, with a special mesh). Such a measure is needed to prevent trash from entering.
When installing in the attic be sure to keep the distance from the nearest window - 4 meters.
The minimum diameter of such an element is 110 mm. However, the more the better.

Having received all the necessary knowledge, you will need to create a plan-project of your sewer system. For convenience, you can use various computer programs for modeling.

Choosing a material

When you have planned the location of all the elements, you can proceed to the choice of material. We recommend that you use plastic products (PVC, polypropylene or polyethylene).

This material has long been diligently pushing the main competitors out of the market due to its many advantages:

Relatively low price. When compared with stainless steel or copper products, in this aspect, plastic has a huge advantage.
Durability (under normal conditions, the service life reaches 50 years).
Wear resistance.
Ecological purity.
Easy to use. Practically anyone can install sewage pipes with their own hands. For convenience, there are many different fittings that facilitate the work.

There is another option - cast iron. Such a system will cost you a little more, and the work will require certain skills from you. But such a system will serve you much longer (according to manufacturers - at least 100 years).

Cast iron has an impressive weight, which in some cases plays an important role

It is also worth noting that cast iron perfectly absorbs sounds, which eliminates the need to create a noise-absorbing box.

We perform work

That was the turn of the most important part. If you do not know, for example, at what depth to bury the sewer pipe, then the information below is especially for you. We will analyze all the details in detail.

Excavation

The first thing you need to do a little work with a shovel.

Consider the order of work:

The depth of the sewage pipes for SNiP should be greater than the level of soil freezing (this figure depends on the region). The trench will have to dig a little deeper than this value, because the tab must be done on a pillow of sand (5-10 cm). In addition, do not forget about the required slope, so add a few tens of centimeters (depending on the length of the outer part).
Having dug a trench, we lay pipes on its bottom.

Connection to a well or cesspool must be treated with a sealant

The connection of elements must be started from the foundation, through the hole previously made in it.. The smooth end is greased with silicone and inserted into the socket.
Then the outer tube is connected to the one that goes out of the house (inner). To change the need for movement of waste, use the taps of 30 or 45 degrees. It is necessary to connect elements from plastic against the stop, manually.

Note! If the length of the system exceeds 15 meters, then we must make access to it at every turn in order to carry out inspection if necessary.

Having collected the highway, it is necessary to warm it with some insulating material.. If necessary, you can wrap a heating cable.
After that, it should be filled with sand, not forgetting the tamping from the sides. Top ram can not be!

Remember that if you have a cesspool, then from time to time you will call the machine for pumping sewage from it. Therefore, place it in such a way that it can be accessed.

Build Tips

Assembly of polymer products is usually not difficult, even for inexperienced in this business masters.

Therefore, we will not analyze the methods of welding or joining using fittings, but consider the key rules that are specific to the systems we are describing.

Try to make as few joints and turns as possible. Such a measure will ensure the longevity of the system, for each such element is a potential leakage or clogging point.
Do not forget about the installation of fan ventilation. It equalizes air pressure and prevents unpleasant odors.
The connection must be mobile. The fact is that when the temperature changes, the elements expand. If they are installed "tightly", then the deformation can not be avoided.
If for some reason you have insufficient depth of sewer pipes (for example, if the ground does not allow it), it is imperative to use a heating cable.
In some cases it is advisable to use flexible wiring. Especially often this solution is used to connect washing machines and dishwashers.

The final connection is best made using flexible elements. This will greatly facilitate your work.

In conclusion

So our story has come to its logical conclusion, but you can supplement the knowledge gained. In the presented video in this article you will find additional information on this topic. Viewing this video will allow to understand all the nuances.
