We expose the correct angle of the sewer pipe

Being engaged in the construction of sewage with his own hands, it is necessary to take into account many factors and rules that affect the result of work. And an important aspect of this process is the angle of inclination of the sewer pipe set by the rules.

If you do not know exactly the answer to the question, we will try to tell you in this article as much useful information as possible to facilitate your work later.

We equip the sewer system - the basic rules

Before starting the work process, you need to know and do not forget:

• The less turns and joints in the pipeline, the less the likelihood of leaks and stasis. Also creates additional resistance to liquids. Especially if the slope of the sewer pipe is not observed, then the presence of a complex system is even more harmful to the movement of water.
• Cutting of the sockets is not recommended, since elements with chips, cuts and even small cracks should not be installed in the sewer system. As for metal elements, take care of the absence of burrs and sharp edges that can damage the joints.
• Incorrectly fixed sewer pipe will lead to abnormal operation, and if in the case of cast iron and metal pipes it is not critical, then plastic materials are subject to deformation. Therefore, additional mounts should be installed with a small pitch (70-130 cm).
• Do not use rubber seals, purchased separately from the pipeline elements, they can not provide full density at the joints.

Note! To facilitate the process of connecting pipes, you can use any kind of remedy as a lubricant, for example, liquid soap will do.

• Do not forget that the lower the price of purchased materials, the less likely to get a quality sewer system.

Pipeline without stagnant water

To calculate the correct angle of inclination of sewer pipes, the following aspects should be considered:

Note! The optimal level of the pipeline angle per meter is from 4 to 8 centimeters, this is under good conditions, when there are no problems with sewage.

1. Throughout the sewer pipe, the slope is measured from the flatness of the floor, for this purpose the construction level is used. After all, at first glance, a perfectly smooth surface is not always so, most often, drops exist and are possible up to several centimeters per meter.

1. Typically, the angle is measured per linear meter of the pipeline, and the diameter of the sewer should also be taken into account.:
2. 50 mm cross section - at least 30 mm per meter.
3. With a diameter of 110 mm - the angle should be about 20 mm per meter.
4. Larger sections (160-200 mm) are installed with a slope of 7-10 mm.

Note! All these indicators depend on and can vary depending on the number of turns and joints, devices connected to the sewer system.

1. Take into account the nature of the load on the sewer, for example, if the water is drained from the washbasin, then you should not worry about stagnation, the angle can be set to the maximum. And for toilet bowls and shower cabins, it is necessary to strictly follow the calculations and rules so that the liquid moves evenly through the pipes.

In this case, too steep slope is also harmful, as well as insufficient, due to the fact that the water leaves the pipes too quickly, leaving a dried solid residue on the walls. It is a smooth descent allows special cleaning agents to clean these contaminants.

Also, a steep angle can cause water constipation, contributing to throw sewer "flavor" into the living room.

Pipeline full

There are special formulas that allow you to calculate various parameters, for example, important when laying a sewer system - its occupancy with liquid.

The formula is as follows: Y (fill) = H (possible height of the water level) / D (diameter of the pipe).

To understand the correctness of the calculations:

• If the occupancy rate is 0, then, accordingly, it is empty.
• If the indicator is equal to 1 (or more), then this indicates 100% fullness.
• Best of all, when the indicator varies from 0.4 to 0.6, it indicates normal operation of the sewer system.

According to the SNiP

Well-known building codes and regulations allow the installation of the sewer system correctly and for a long time. In this case, SNiP makes all the necessary calculations long before the construction of the house, and at the design stage.

To understand, all records about the calculation of the angle are made in centimeters (millimeters), no one makes measurements in degrees, since even the slightest mistake can be the beginning of repair work.

And if troubleshooting is not so problematic in private houses (it is possible with your own hands), then in multi-apartment buildings such repairs can cause many complications. The instruction in the SNiP will not allow you to allow a miss.

Conclusion

Now we hope that the above information will help you in solving the problem, and you will easily find the answer you need. If the sewage system has already been laid, and you notice any deviations, then you should turn to the set angle, and what if it is far from the norm?
