Description of the elements of the drainage system and methods of their connection- Review + Video The gutter on the roof of the house plays a very important role in preserving the entire structure in its original form. Experts say that a roof without a drain will last several times less. In addition, the walls of the house, the blind area, the basement lend themselves to destruction.

The cement mortar is washed out, the masonry is destroyed. In order to avoid such problems, you need to take care of the drainage of rainwater.

The elements of the drainage system make up a single whole, thanks to which you can keep the house safe and sound.

A gutter is a system through which water enters a gutter, and through it is discharged into a tank or drain. Everything is done by itself, without any outside interference. The main thing is to equip the drainage system correctly. You can cope on your own without involving specialists.

You shouldn't have any special difficulties in your work.

The principle of operation of the drainage system

First of all, familiarize yourself with the principle of operation of the drainage system and its installation. Examine the elements and types of systems (internal and external). An internal roof drainage system is installed in high-rise buildings with a flat roof. Installation is carried out inside the house.

External gutters are installed in private houses with pitched roofs. All elements are fastened outside the building. They are usually divided into 2 types:

  • Description of the elements of the drainage system and methods of their connection- Review + Video Industrial;
  • Self-made.

Everything is obvious from the name. A homemade drain is constructed from sewer pipes or galvanized steel.

Industrial types are produced according to a certain standard, they have installation instructions in the package, all the necessary elements are in a ready-made kit, which is very convenient, you do not need to look for anything else. Products are available in many hardware stores. Just buy the kit, fix the roof gutter system to the rails and transport it to the installation site. But, before buying the entire system, decide on the material of the elements.

The modern market offers customers a wide range of products for various purposes.

The same applies to drainage systems. Now you can choose not only a functional water drainage system, but also one that has an attractive appearance. This needs to be done to give the house a complete look. As for the cost, there are drainage systems for different wallets - from the cheapest to the most expensive.

Types of systems

Plastic drainage systems

  • Advantages:
  • Affordable price;
  • Light weight;
  • Long service life;
  • Resistance to aggressive external environment (alkali, temperature fluctuations, sun rays);
  • Easy to install;
  • Noise isolation.

For the installation of a plastic gutter, the socket method is used together with seals or glue. In addition, plastic does not corrode and is not subject to putrefactive processes. The service life of such a drain is about 25 years.The choice of colors of the drainage system is also quite wide, which makes it possible to choose exactly what you need. Of the shortcomings, it is worth noting that in the cold season, the water can stagnate, freeze, and the gutter will crack as a result.

Galvanized gutter systems. Such options produce their galvanized with the imposition of a protective coating (zinc or polymers). This makes the system elements resistant to rust formation, extending the service life. The disadvantages include high noise levels and possible installation difficulties. The shape of the gutter can be rectangular or round.

The service life of the metal gutter system is 15 years.

Copper gutter systems. This is the most expensive and attractive type of these systems. Copper has the ability to resist rust formation, is strong, reliable and has a long service life. An important advantage is the fact that the entire structure is lightweight, so there are no difficulties with installation.

The elements of the system are connected by soldering. Copper has the ability to darken over time, but this does not spoil it at all. The service life of copper gutters is the longest and is about 150 years. Therefore, we can say with confidence that the high cost of the system pays off completely precisely because of this quality.

When choosing a material for making a drainage system, pay attention to what the roof of the house is made of.

The tiled roof will blend in with the copper gutter. Any other roofing material will look great with both plastic and galvanized gutters. However, as they say, the owner is a master, you can choose any material, both for the roof and for the drainage.

Elements of the drainage system

The system of drainage from the roof, consists of elements that are attached to each other, forming a single whole. Each of them has its own function, and the design itself is outrageously simple.

Let's try to consider each element separately.


This is one of the main elements of the system, which is a kind of channel responsible for collecting rain and melt water. The sediment is subsequently discharged through a chute into a drainage system or reservoir. The shape of the gutter can be square or round. You can choose any, at your discretion, there is not much difference in functionality.

Note. Square gutters are more difficult to clean than semicircular gutters as dirt collects in the corners and is difficult to remove.

Installation of the gutter system takes place at the eaves of the roof, in the area of ​​the lower lathing. Flowing down the ramp, water enters the gutters. An important point is the choice of the optimal diameter for this element.

It depends on the area of ​​the roof, and the larger it is, the more water will enter the gutter. The length of the element will directly depend on the perimeter of the building. The components of the drainage system include connecting elements for gutters.

Gutter system pipes

Description of the elements of the drainage system and methods of their connection- Review + Video In second place after gutters are gutter pipes ..

. And this is logical, because it is in them that waste water gets. The installation is carried out vertically, and the precipitation is sent to a specially designated place.

One pipe consists of several small parts. The connection takes place using several methods, which depend on the material of manufacture of the pipes.

From the pipe there is a branching of the outlets of the drain (drain bends), and the pipe bend, at a certain angle. The height of the house dictates the length of the pipes. Section in the range of 75 - 110 mm, depending on the angle and area of ​​the roof slope.

Drainage funnel

This element of the system is designed to connect gutters with pipes. The main function of the funnel is to direct waste water from the gutter into the pipe.

The system is pretty simple, no secrets.

Types of funnels:

  • Flat - designed for installation on flat roofs.
  • Bell caps are used for installation on complex roofs.

When calculating and fixing the drainage system, take into account that the number of pipes affects the number of funnels. It is important not to allow clogging of the element, since the system will overfill with water and will not fulfill its purpose.

Waste water will flow outside, pouring out onto the facade and houses. In frosts, the water will freeze and the entire system will fail. To prevent a possible development of events, the funnel must be protected with a special grate that prevents debris from entering.

Note. Like funnels, gutters also need to be protected from debris and dirt using a grate.

Plugs and brackets

Gutter system brackets are special fasteners that fix the gutters. At first glance, it may seem that such a small detail does not really matter. But in fact, you cannot do without it. Fastening is carried out to the roof lathing or to the cornice. The brackets are attached to the wooden crate with self-tapping screws.

The fixing distance between this element made of plastic is 60 cm, for metal 110 cm.

The main function of the plugs is to prevent the flow of waste water from the free end of the gutter.


This element is used to fix the vertical drain pipes against the wall. Each type of metal has its own specially designed parts. For installation, they need to be screwed into the wall, after which pipes are inserted into them.

For low-rise buildings, it is enough to fix 2 clamps. The higher the building, the more elements will be needed. For metal they are one, for plastic they are different. They are screwed into the wall and then the pipes are inserted. The number of pipes determines the number of clamps.

There are not many elements in the drainage system, but they are all interconnected, although I each perform their own function.
