Plumbing pipes - this is a fairly extensive range of products that have a lot of variables, starting with the material of manufacture and ending with the size. Of course, such a wide spread technical specifications has arisen not just because after all, for different plumbing functions, quite specific elements of the pipeline are required.
In such conditions right choice A suitable material is not an easy task. In order not to make a mistake with the choice, you need to know the types of plumbing pipes and connections, as will be discussed in this article.
Plumbing pipes for cold water supply
The presence of cold water is required in any building, regardless of its functional purpose, be it multi-apartment construction, a private house or a warehouse. Cold water supply is often carried out even in those places where heating or sewerage are not required at all.
Materials for equipping the pipeline required for cold water supply can be:
- Cink Steel;
- Stainless steel;
- Copper;
- Plastic.
Zinc coating provides complete protection of the pipe against corrosion. Unfortunately, not everything is so smooth - if the zinc layer at least in one place is damaged, then nothing will prevent the formation of rust. The problem is that when welding or thread cutting, the zinc layer is inevitably damaged.
Naturally, the use of pipes made of "black" (non-galvanized) metal for the water supply is impossible: the condensate always comes to the surface of the pipe, because of which it will all be covered with rust. In turn, rust breaks the integrity of the pipeline, and it can no longer perform its functions.
To protect steel plumbing pipes from corrosion, we have to use bypass methods. The most common of these is coating the pipeline with paint, but even this does not save the pipe from corrosion. In addition, the internal cavity of a galvanized pipe overgrows with time, so its throughput significantly decreases.
Avoid problems by using stainless steel pipes. Of course, this option has drawbacks - high in comparison with conventional steel cost, and difficult installation, especially when there is no thread. If we talk about the positive qualities, the stainless steel is characterized by maximum strength and a long service life.
The best option in relation to the same steel will be copper pipes. On the performance characteristics, steel is significantly inferior to copper, the pipes of which are not susceptible to corrosion. However, copper pipes coated more effectively will work polymer layer - in this case, it will be possible to avoid the appearance of all the time the condensate flows.
In the case of cold water supply, advantages plastic pipes obvious, so the replacement of metal analogs has become quite natural. Considering the simplicity of the systems necessary for cold water supply, it is the polymer plumbing pipes for water supply that have become the best option.
Plumbing pipes for hot water supply and heating systems
In the case of pipes through which a hot liquid must pass, everything is different. The most important factor is the ability of the material to withstand heat over a long period of time. In addition, it is necessary to take into account the much lesser degree of occurrence of plaque on the inner surface of the wall, which is characteristic of hot water supply and heating.
Quite suitable material for such a system will be "black" steel, because the missing condensate will not allow rust to appear. True, in such a system the liquid must be constantly present, and the system itself must be leakproof. Even a momentary drain of water will lead to a rapid appearance of rust.
Even better in such conditions, pipes from stainless or galvanized steel will show themselves. Copper pipes will also be an excellent option, although they will have to accept the very high cost of such material. In addition, in this case, thermal insulation is required, which will further increase the costs of pipeline construction by an order of magnitude.
In heating systems, it is possible to use polymer pipes, but not all of them - standard polyethylene pipes can operate at temperatures not exceeding 80 degrees. Cross-linked polyethylene and chlorinated PVC are suitable for more stringent conditions - they can withstand temperatures of up to 95 degrees.
Best characteristics among polymer pipes demonstrates reinforced polypropylene. Due to the layer of aluminum foil and fiberglass polypropylene retains its shape.
In principle, polymer pipes for plumbing water supply and sanitation are a good choice, but you just need to carefully study its characteristics before purchasing. It is necessary to understand that the price of modified polymer pipes is quite large and quite comparable with metal analogs, so we will have to weigh all the pros and cons of different materials.
By the way, a major advantage of plastic plumbing pipes is the ease of maintenance. In any system, a large number of build-ups accumulate over time, but for the polymer pipes of this time more is required, and the cleaning process itself will not be difficult.
Sanitary sewer pipes
Sewerage is another kind of plumbing system, which also makes its demands on the pipes used. For sewerage, plumbing pipes require special, because the main requirement in this case is the ability to withstand the impact of corrosive substances.
For sewage systems the following types of pipes are used:
- Cast-iron. Being not very suitable for other applications due to low strength and high weight, cast iron is successfully used in sewage systems. Unlike steel products, of which there is no point to say this case, cast-iron pipes perfectly resist any aggressive environment. In addition, this material extinguishes sounds well, therefore it is often used in pipelines of apartment buildings.
- Plastic. PVC pipes are also well suited for sewerage systems. The popularity of plastic pipes owe a wide range, simple installation, good performance characteristics and high resistance to chemicals. Conventional PVC pipes can not work at temperatures above 60 degrees, but this is usually quite sufficient to work in a sewage pipeline. In extreme cases, you can choose polypropylene. It is also necessary to know that the small dimensions of plumbing plastic pipes give them lightness, but do not completely hide the noise of the fluid moving inside the pipeline.
- Asbestos-cement. When sanitation is installed, pipes made of asbestos cement are often used. However, in the overwhelming majority of cases, such products are used to create industrial sewage, and not for domestic systems. The fact is that the installation of asbestos-cement pipes is complicated, and they themselves are rather fragile and differ in weight.
- 40-50 mm - slope is 3.5 cm per 1 m of the pipeline;
- 100-110 mm - the slope is 2 cm per 1 m;
- 110-150 mm - the slope is 1 cm per 1 m;
- 200 mm and more - the slope is 0.8 cm per 1 m.
Dimensions of sanitary pipes
The diameter of the plumbing pipes always depends on the specific requirements for the system. The operating pressure, temperature and number of connected devices directly affect the size of the materials used.
For different systems there are different requirements, which look like this:
- Cold water supply. Selecting pipes for transporting cold water, you must always consider the probability of overgrowing the system. The thinnest option that can be used in this case is a copper pipe 12 mm thick, which is quite suitable for a household system equipped with cleaning filters. You can also use steel pipes, but their thickness should fluctuate around 15-16 mm. Using plastic pipes for cold water supply, it is necessary to choose products with a diameter of at least 20 mm - their internal dimensions will be comparable with the diameter of thin-walled metal analogues.
- Hot water supply and heating systems. For the transport of hot water, the pipe dimensions will be exactly the same as in the previous case. Mounting the heating system, the diameter of the pipes should be increased - the minimum value of copper and steel products should be 20 mm. Of course, for pipes made of polymer this value will increase even more - up to 25 mm. However, too wide plumbing pipes should not be used - pipes with a diameter of more than 50 mm are used only in industrial facilities.
For the arrangement of sewerage, special calculations are required, which are affected by many factors. But at designing it is possible to not consider type of a material - the sizes of sanitary pipes do not depend on this parameter.
The selection of the sizes of sanitary pipes, depending on the scope of application, is as follows:
- 50-100 mm. Such pipes are used in sanitary units between one or two devices (sinks, washbasins, shower cabins).
- 110-150 mm. This pipe diameter is used for several simultaneous devices and a toilet bowl. In addition, pipes of this size are suitable for mounting a vertical riser.
- 150-200 mm. These pipes are suitable for connecting several sanitary devices and toilets. This pipe size can also be used to form a common drain.
- 200-300 mm. Pipes of this size are used infrequently. The main application is the installation of a connecting section between two water receivers.
There are also plastic pipes with a diameter of less than 500 mm, but they can only be used in small kitchen sewers.
Conclusion
In this article, pipes for plumbing and their application have been examined in detail. A properly designed system, in which the relevant materials are used, will fully and fully perform its functions.
In this video I want to introduce you an elite bathroom. This bathroom was installed and launched in 2002. The video is removed after 10 years. As seen on the video from that moment nothing has changed. Everything works like a clock. Why?
There are several main reasons for this. The main reason for the long operation of the water and sewerage systems, as well as the faience of the faience, is certainly the quality of the pipes and the faience itself. For the installation of systems, metal-plastic pipes and technology press fittings were used.
German sewer pipes and fittings were used for sewerage installation. Also, when assembling the sewer, a special lubricant was used. Lubrication makes it easy to assemble a sewer with a fairly tight connection. Freezing, lubrication provides additional sealing. What to disassemble then sewage is not possible for all its elasticity.
Let's start the review from the shell, or rather from two shells on one table top. The video shows that using euro sizes helps to connect faience faience in any scenario. So in our case, the height of the connections was good.
Mistaken a little with centering on the countertop. This happened, because the table top was provided almost to the installation. Therefore, if you want everything to be perfectly connected, then you should take care of the availability of faience or its exact dimensions in advance.
The main problem with not observing the dimensions is the connection of the siphons of the sink. Since I am not a fan of corrugation, in order to connect the sink to the factory siphon, it is necessary to work a little.
And today most masters do not bother with such obligations. And they do it anyhow. But as you can see on the video, that even if you are a little mistaken on the axes, then you can show a witty connection of the siphon, collecting it from two sets.
The next element of our bathroom is the shower.
When choosing a shower cabin, you should pay attention to its size. For example, for people below average growth, you can use a 800x800 mm cab. People of medium height and above in this cabin will be a bit crowded. In this case, recommend 900x900 mm, and better 1200x800 or 900 mm.
The shower mixer should be installed in the center of the cabin at an altitude of 1200 mm.
Although there are exceptions here. The mixer can in some cases be moved to the side, and in the center, for example, to mount the shower stand.
Sewage is installed at a height of 100 mm from the floor, but as practice shows for the shower it is necessary to mount a drainage outlet, the lower the better.
You can also draw a conclusion not far from the edge. There are shower trays, they are thin and are installed level with a clean floor.
Sewage can be hidden, for example, in a pie of a warm floor or mounted on the ceiling of the lower room. It is still very often impossible to adjust the height of the sewage system to the pallet, because often the shower is removed from the riser. In this case, the pedestal, which is poured under the pallet, will help you.
Be sure to pay attention to the drainage drowned in the pedestal and the drainage outlet turned from the pedestal from below. The main thing is the practical skill - to start doing, not to sit and think. When you do, try, fit and look.
This word is most clearly characterized by the principle of the bath. Jacuzzi baths are divided into two types according to the principle of filling. There are baths filled with a conventional mixer, which is mounted on a wall. Then you need to clearly measure the size of the bath, since they do not always have distinct perpendicular shapes. It may happen that the mixer falls into such a bend, and the water will splash in different directions. The height of the mixer is 800-850 mm for baths of standard height.
Baths of Jacuzzi of the second type are filled with a mixer built into the bath itself. To do this, it is also desirable to have a bath size or at least can visually inspect it. In doing so, you should see the location for the installation of the terminals.
This is usually a wide place under the bathroom and there are hoses for connecting water to the bath. Also determine where to install the drainage outlet. If it is not known, then the water output is made as an option from the edge of the bath inside at a distance of 450 mm, and the height is 350-400 mm and the width between the terminals is 150 mm. Sewage is done at a height of 100 mm along the axis, if from the wall and just as far from the edge of the bath, so that you can service the connection, while not going far under the bath and not pushing it away.
If the toilet is mounted one, that is, without a bidet, then first closer to the door we mount the sink and the second number of the toilet. According to statistics, it is the toilet that is the second element in the frequency of use after the shell.
If you do not have the opportunity to mount the bidet, then you can mount just a shower faucet next to it, which is called a hygienic shower.
Sewer for the toilet is usually removed from the wall to a height of 180 mm along the axis, with the outlet of the toilet bowl straight. If an oblique conclusion, then the sewer must be lowered to the finishing floor. It is also very convenient to make the sewage outlet from the floor close to the finishing of the wall.
At the same time, it is very convenient to connect the toilet bowl with factory pipes with Vega siphons. There are straight pipes and at an angle of 90 degrees and 45, respectively.
Water to the toilet can be connected in several ways. Previously, almost all the toilet bowls came with a top connection to the tank. For this, the water output is made at a height of 600 mm to 800 mm. Depends on the height of the toilet itself.
The location with respect to the right or left edge of the toilet is chosen individually, so that on one side the connection can not be seen, and on the other hand there was good access to it. The distance from the toilet axis is 300-400 mm.
Now most of the toilet bowls come with a lower connection, so when mounting the water outlet we use a height of 350 mm and a size from the toilet shaft 150-300 mm. It depends on whether you want to see the toilet tap or not.
Now let's talk about connecting a bidet. Looking at what kind of connections for the bidet do the plumbing I come to the conclusion that the bidet is a dark horse out of all the san faience. Although everything is very simple. The water and the sewage system for the bidet are mounted at a height of 100 mm from the finishing floor.
The only rule for installing water connections is that the height remains unchanged. But the distance between them is two sizes. If the bidet is placed close to the wall, then the distance between the water outlets is 80 mm along the axis.
If the bidet is of a rounded shape and is not intended for close mounting, the distance between the terminals is 320 mm along the axis.
Here are just a few photos of the installation of a heated towel rail or drying on a folksy.
There are also unusual sizes that we will consider in the following videos. In the meantime, you can start simply by marking on the wall of your next object. And then you will see what is and how it is located. You can visually see and feel usability, that is, how convenient or uncomfortable it will be to use sanitary faience.
This article is devoted to an analysis of what size plumbing pipes can be, what materials they are made of and for what purpose.
Pipes in plumbing can be used for:
- Water supply;
- Heating;
- Sewer.
Traditional materials and routing of pipes - plumbing of the seventies
At the same time, if we talk about the choice of materials, here it is more likely to include heating and hot water supply to one category, and cold water supply to another. Too different requirements for cold and hot water to the water supply.
Cold water
Materials
- Non-galvanized steel. Black steel pipes for plumbing without anticorrosion coatings - the worst choice for cold water supply.
Cold water is always a condensate, that is, a combination of dampness and air. If so, the pipes will quickly rust. A layer of paint will only partially slow down this process. In addition, a steel pipe on cold water rapidly overgrows from the inside, reducing its capacity.
Steel pipes and cold water - a bad combination
- Cink Steel. Here everything is much better: only areas where the zinc coating is broken - the thread and the weld seam - can rust.
Deposits in the pipe are not delayed. The disadvantages are the labor intensity of assembly and the large weight of the pipe. - Copper. Copper pipe sanitary - almost eternal material, aesthetic appearance and not afraid of dampness. But expensive. In the case of cold water, its cost is simply unreasonably high.
Tip: if you decide on copper, it is better to put a copper tube with plastic coating on cold water.
Among other things, it will save you from condensation on the pipes. The copper itself does not harm, but drops on the floor or inside kitchen furniture to nothing.
- Stainless steel. Cheaper copper, but more expensive than zinc. To the laboriousness of the assembly of the water supply, extremely complicated processing was added: it is simply unrealistic, and the turner's sharp tools on it can spoil.
However, the water pipe on cold water, assembled from stainless steel, is also almost eternal and much stronger than copper. - Polyethylene and polypropylene. With regard to cold water, their properties are the same: light, cheap materials whose life cycle in these conditions approximates the duration of human life.
If you plan to replace the plumbing pipes with cold water, this is an ideal choice.
Dimensions
The minimum diameter can be piped with copper pipes: if there are filters for a standard apartment, pipes with a diameter of 12 millimeters will suffice. It does not overgrow with time, while thin walls provide a sufficient clearance at a minimum external diameter.
Then, an ascending steel pipe with a diameter of 15 millimeters follows. diameter 16 millimeters is the most in demand among this material. Used for cold water pipes are polypropylene and start from 20 millimeters. The reason for the last fact is thick walls, providing with a constant external diameter a smaller clearance in comparison with other materials.
Hot water and heating
Materials
What is the difference in principle with cold water? In the temperature and in that hot water contains technical additives, preventing the overgrowing of steel pipes. If so, pipes from materials that are unstable to temperature will be in outsiders, but the steel pipe will be partly rehabilitated.
In general, the types of sanitary pipes here can be estimated as follows:
- Non-galvanized steel in the absence of condensation does not rust, and thanks to the composition of the technical water does not overgrow. However, as always, there is a nuance: the heating systems of apartment buildings in summer should be filled with water.
However, when leaks begin between sections cast-iron radiators or simply summer repairs, they are often discarded. If so - the pipe begins to rust out rapidly from the inside. Oxygen and moisture are both factors. - Galvanizing, on the other hand, does not have these vulnerabilities. The author had to open the heating risers from the galvanizing, which in the 50-60s of the last century were collected strictly on carvings.
Do you know how those pipes differed from the new ones? Nothing. But to collect water from it or heating is still heavier than using many alternatives.
- Copper is made here almost the ideal material. Its heat resistance is very handy. Only the cost and difficulty of installation (especially soldering) cast a shadow on the owner's face of a copper water pipe and heating system.
- Stainless steel also does not give up positions. She did not become cheaper, labor-consuming processing and installation did not go away; However, if you forget about these features - the material is great.
- Polyethylene. Alas, he falls into the number of retired. Polyethylene begins to soften already at 80 C. Downward pipes and fountains of boiling water in the midst of winter just will not please anyone.
- Polypropylene the same holds a cheerful: at the manufacturer's declared maximum operating temperature of 95 C, there are cases when polypropylene for several years stood on water pipes with a temperature of 110-120 degrees. Then, however, it was safely destroyed.
Tip: reinforcement with aluminum or fiberglass increases the strength of the polypropylene pipe, its ability to withstand pressure, and at the same time sharply reduces its coefficient of thermal expansion.
For heating or hot water, a plumbing pipe made of reinforced polypropylene is better.
Dimensions
With hot water, the requirements for pipe diameters do not differ from cold pipes. But with heating everything is different: the slow circulation of the coolant and the large total length of the risers makes it more passable. If you do not take cases of frank hackwork, then copper, plastic and steel are used in heating systems starting from a diameter of 20 millimeters; polypropylene with 25 millimeters.
The upper limit of the diameter is limited by the requirements for bandwidth pipes. In practice, in apartment buildings Sanitary pipes with a diameter of more than 50 mm are used only in two cases: when builders need to dispose of the materials they have, which will not be used anywhere else, and when steel pipes are used to cover the deposits.
Sewerage
The temperature and pressure here are low, but the sewer pipe deals with an extremely aggressive environment. Here, steel is not in demand at all, except in cases of very clinical idiocy; Copper is also not used, but iron and asbestos-cement pipes are added.
Materials
What materials are used for plumbing in the case of sewerage?
- Cast iron was traditionally used in Soviet-built houses. Cast-iron sewerage is strong enough, however it is strongly overgrown with deposits and hardly cleaned; Connections are assembled with manual sealing of joints, and if so - with great time and effort. For plumbing, replacing pipes from cast iron is a difficult test.
- Asbestos cement in houses is used extremely rarely. Assembling sewerage from asbestos cement - a pleasure below the average: joints have to be closed with cement mortar or sulfur with its flavors. In addition, these pipes are quite fragile.
- Polyvinylchloride is the most common now as a material for sewerage. Pipes are light, they cut without any effort, they are assembled by simple docking using rubber seals.
Among the shortcomings can be attributed except that the relative fragility of the material: zapnuvshis about such a pipe, it still can be damaged.
- Polyethylene. Here he wins his failure with hot water. Externally, the pipes differ from PVC only slightly thicker walls, but the greater elasticity of polyethylene makes it a much better choice.
Dimensions
The thinnest sewer pipes - 40 mm PVC - used in the assembly of kitchen sewers.
For risers, pipes of any material having a diameter of 100-110 millimeters can be used; if only the kitchens are located on the riser, it is practiced to assemble it from PVC pipe or cast iron with a diameter of 50 mm.
The horizontal sections of the sewerage, which unite several risers, and the outlets on the well, are made of a pipe with a diameter of 150-200 millimeters; with a small number of apartments and there you can find a pipe-weave.
Pipes of larger diameter are usually used to combine wells with a collector.
Conclusion
Here, in principle, and all about the pipes that are now used in plumbing. Good choice and quick repair!
Sooner or later, every owner of a house or apartment has to choose sanitary sewer pipes. This does not depend on whether replacement of old systems is required or if they are mounted in a new room. We will understand in more detail which communications are on sale, and also what advantages and disadvantages they have.
Types of pipes
The main types of products available for sale are pipes made of steel, copper, plastic and plastic.
Selecting a particular species should be based on individual conditions, taking into account the expected operating conditions.
Steel structures
Until relatively recently, almost all plumbing pipes were steel. This is a cheap kind of material, to which it is always possible to select suitable reinforcement without problems.
The main advantage of the material is strength. Thanks to which they withstand pressure drops, they do not have a terrible high temperature.
At the same time, condensate forms on such pipes. In addition, for installation requires the use of special equipment and skills of the master, you need welding and threaded connections.
If the installation is performed at a qualitative level, the steel sanitary pipes will have a long service life, up to 40-50 years.
Summarizing the shortcomings, we can note:
- complex and costly installation;
- the formation of lime, which leads to "overgrown" pipes;
- formation of corrosion;
- high electrical conductivity.
Specialists recommend the use of sanitary and sewer steel pipes in cases of replacement of certain parts of the old water pipe, in order to avoid combining and combining different materials. In other cases, it is better to abandon steel structures. And if you need to connect different materials, it's easiest to use special adapters.
Copper pipes - a quality and expensive option
Plumbing copper constructions are not only high-quality, but also externally attractive. Their disadvantages include high cost, which is compensated by a long service life. Copper structures are operated up to 60-70 years. They do not deform and have a high level of resistance to temperature changes.
As additional pluses - copper is useful for the human body. Everyone knows that tap water contains chlorine. Copper avoids the formation of harmful substances when combined with chlorine.
The disadvantages of these designs include:
- High cost;
- Installation of plumbing pipes made of copper is complex and costly;
- A pre-established water treatment system is required;
- Low resistance to mechanical influences;
- The choice of the pipes themselves and the bundling to them in stores is not wide enough.
Pipes from металлопластика
This kind of material is easy and convenient to install and replace. He occupies one of the leading positions. The material is a three-layer construction - the frame is made of metal, sealed on both sides in plastic.
Metal-plastic is able to withstand water temperatures up to +75 C, as well as pressure drops. The operational period is 30-35 years. Fittings are used to join the pipes.
The disadvantages of metal-plastic products include:
- The material does not withstand the water temperature too high;
- The need for regular pull-up connections;
- Low level of strength of joints.
Pipes made of metal-plastic are best used for installation of plumbing structures in the country. Apartment or house requires other practical options.
Popular plastic pipes
This species is, if not the most popular, then the most popular consumer. From such material, both internal and external water pipes are installed.
Plastic pipes have high strength, low cost, they have a decent appearance, are not corroded and have a long service life.
Installation of plastic structures will be carried out even by a novice using a soldering iron, special glue and fittings.
Plumbing plastic pipes include several types:
- PVC. Are inexpensive and practical. Plumbing PVC pipe can be used for hot and cold water, as well as for installing a heating system. The most rigid kinds of PVC are connected by fittings, adapters and special glue.
- The widest scope of use is polypropylene pipes. It is not difficult to connect this material, using a coupling and butt soldering.
- Polyethylene constructions are distinguished by their strength and elasticity. If the water freezes, they will not burst, and soldering is used to connect them. Cross-linked polyethylene allows them to be used for hot and cold water.
Their main disadvantage is the need for cutting during repair and replacement. The photo shows various materials pipes.
Dimensions of plumbing pipes, depending on the material
The dimensions of the plumbing pipes, depending on the material, are shown in the tables below. Millimeters and inches are used for marking. In this case, 1 "is 25.4 mm.
For copper products, the dimensions of sanitary pipes are minimal. For installation of the water supply system in the apartment, pipes with a diameter of 12 mm are suitable.
For steel products, the optimal diameter is 15 mm.
| Diameter of steel products | ||
| Thread (mm) | Diameter of internal section (mm) | Notation |
| 20,4 — 20,7 | 12,7 | 1/2’’ |
| 22,4 – 22,7 | 15,9 | 5/8’’ |
| 25,9 – 26,2 | 19,0 | 3/4’’ |
| 29,9 – 30,0 | 22,2 | 7/8’’ |
| 32,7 – 33,0 | 25,4 | 1’’ |
| 45,8 – 46,2 | 38,1 | 1,5’’ |
| 57,9 – 58,3 | 50,8 | 2’’ |
16 mm - the most demanded size of a plumbing pipe made of metal-plastic.
The size of polyethylene products should be 20 mm or more. Depending on the manufacturer, the dimensions of the products can be indicated either in inches or in the metric system.
If you need to connect several different materials among themselves, adapters are used. They allow you to take into account the appropriate dimensions.
Cleaning of sewer pipes
Sewer pipes can be made of cast iron or plastic. Cast-iron sewage is not cleaned using chemicals, which can lead to leakage.
Cleaning cast-iron sewage can be carried out either by a plunger or a cable. In some cases, the sewer can be cleaned with soda and vinegar. The Vantuz is suitable for a sink, washbasin and bath. However, the use of a cable is the most effective and proven method.
Cleaning of sewer plastic pipes can be carried out with salt, as well as with alkaline agents, which allow to eat away the blockage, leaving the structures and systems themselves intact. The use of mechanical methods of cleaning the sewer should be extremely careful to avoid damaging the plastic material.
It should be noted that sewer pipes made of plastic deliver less problems in terms of formation of blockages than cast iron. The latter differ by the roughness of the inner surface.
Installation, operation and replacement rules for each type of plumbing pipe are individual. Therefore, one should seriously approach the choice of material depending on specific parameters, as well as preliminary calculating their cost.
