Choosing outdoor sewer pipes

Without a high-quality sewer system, it is simply unrealistic to provide an appropriate level of comfort for a modern home. But if you save on its construction, then provide yourself with a whole brood of problems, so that all elements of the drainage system should be of better quality.

Especially carefully choose the external sewer pipes. Fortunately, modern industry can offer a huge amount of high-quality and durable materials, so this is not so difficult.

In large effluent systems, pipes made of asbestos cement, reinforced concrete, cast iron or polymeric materials can be used. However, in recent years, asbestos cement or cast iron pipes have practically not been encountered, since their cost does not correlate somewhat with the performance characteristics. In addition, the recently widespread polymer outer sewer pipes are much easier to maintain and install.

In particular, being so popular relatively recently, metal pipes have a bunch of serious drawbacks. The most obvious is poor corrosion resistance. It is believed that in just one year, a standard steel pipe is thinned by at least one millimeter. If we take into account the rigid effect of stray currents and possible soil features, then in some areas the service life of this kind of material does not exceed five to six years. Such a sewer pipe (external) is not only expensive, but also does not justify its high price.

And therefore, when choosing the most suitable material, several important parameters should be taken into account at once:

• strength characteristics;
• wear resistance;
• ability to tolerate exposure to aggressive chemical environments;
• resistance to temperature extremes.

Consider those external sewer pipes that more closely meet all of the above requirements.

Asbestos-cement varieties

These light and durable pipes are made from asbestos and Portland cement. Given the smoothness of their inner surface, they do not clog too often. Unfortunately, their significant drawback is a somewhat increased fragility, and therefore it is necessary to work with such pipes as carefully as possible.

Polymer models

These outdoor sewer pipes are most commonly used recently. They are very durable, light in weight, easy to install and almost not subject to blockages. The disadvantage is that for their proper installation, it is often necessary to use special welded machines that require the presence of electric power at the facility under construction. However, given their low price and high performance, one can easily come to terms with these “roughnesses”.

Cast iron pipes

No matter how good the polymeric materials are, their mechanical strength and resistance to elevated temperatures leave much to be desired. Cast iron is characterized by high reliability and longevity, as well as good resistance to aggressive chemical environments. Its lack of weight, as well as the complexity of the connection.

Thus, external sewer pipes (the price of which depends on their type and manufacturer) must be chosen wisely, focusing on your needs.
