The unit of drainage system - a very serious matter which can not be done by eye. Circumvent many pitfalls will only truly rigorous and balanced approach.
Water drainage system is very complicated and consists of many elements, such as pipes, clamps, elbows, tees, plums, brackets, gutters and so on. A necessary condition is to match the number and size of gutters and roof area of the configuration volume of diverted rainwater. As a rule, to 100 square meters. m square pitch enough to bring the trench to a small water pipe. For twice the area required slope or install an additional drain pipe, or increase the number of items. There is a limit on the length of the gutters to the receiver of water - it should not exceed 10 feet, otherwise you should install another drain pipe.

To avoid errors in the project are tentative plan of the drainage elements. The most convenient way to depict a plan for photocopies of drawings of the roof, in order to clearly see the entire system and its individual elements. When the plan is checked, proceed to installation.
Standard mounting scheme is as follows: first, strengthen the horizontally placed details such as plums and gutter. Then hang the vertical drain pipes. Carry out the installation depends on the type of building, the facade of the characteristics and features of the roof. When you replace the drain can be re-erect the new elements to the old mount. Is important, at what stage of construction is carried out installation of drainage. It is advisable to do so during roofing work, using available scaffolds. But if the walls are plastered or paneled be siding, then drain the system better to mount at this stage, or already reinforced drainage pipes will interfere with decorating.
A separate problem is the choice of form and materials runoff. On the one hand, round gutters are cheaper than rectangular, because made by a simple technique and requires less material, but sometimes it's better to choose rectangular drains, if required by design. The capacity of sewers with shaped cross-section may be smaller than that of counterparts with a circular cross section, also more likely to clogging.
Drains can be made from various materials such as PVC, aluminum, zinc, copper, metal-coated. Plastic gutters keep their own characteristics, but are less resistant to mechanical damage, such as a load of snow masses. Copper gutters are more reliable and better looking. Compounds of copper structures propaivayutsya, so the copper gutters and pipes can bend around different parts of construction. Copper has only one drawback - the highest price. The German firm offers a compromise solution Braas - painted the color of copper PVC gutters that are relatively inexpensive and attractive look.
Various coatings solve both aesthetic and practical problems. Polymer coatings increase the service life of drainage and increase their resistance to weather conditions, protecting the metal from the harmful effects.
We should not forget about the so-called winter factor, or at any time you can find icy roof. Russian experts from the State Oceanographic Institute have developed an interesting way to Roshydromet prevent the formation of icicles. To do this, change the design of the roof so that water could not get to the edge. Therefore, the water should fall into the drain pipe before the edge of the roof, and the pipe must not bypass the eaves overhang, and pass it through to the water flowed at once, but did not get to the overhang. When the drain pipe installed vertically on the wall and permeates all exposed structural elements, drainage time is minimized and the probability of icing is significantly reduced. Also, scientists are advised to press the downspouts to the warmer wall construction, and gutters along the warm place of the surface area of the roof.
You can also use more conventional methods such as anti-icing system. In this case, the gutters and downpipes are paving the heating cable, which does not allow water to freeze.
There is a method of protecting the gutter and the roof, as snegozaderzhateli that prevent the fall of large masses of snow. In some countries snegozaderzhateli required, and if they are missing, the house can not be accepted from the builders. Snegozaderzhateli not spoil the look of the house, since the color can be matched to the color of the roof. The company offers a whole Braas kits, including roofing, gutter system, snegozaderzhateli and other items made in the same style that enhances the appearance of the building and construction simplifies the installation and follow it up.
And melt and rain water should withdraw not only from the roof, but also on the way home. If the water is supposed somehow to use, it is collected in a tank, usually underground. If water is not needed, then send rainwater into the drainage system to prevent water from getting into basements through the ground. Drainage is open or closed. In the case of subsurface drainage pipes are placed at a certain depth in the soil around the perimeter of the building or site.
Open drainage, or livnevku use in areas with low groundwater levels. The question of drainage organization should be solved as soon as possible, because of the drainage system depends on the appearance of the site. If for any reason, it is impossible to arrange drainage, the gutter provides knee at an altitude of about 20 cm above the ground, which prevents water flow directly to the base.
On the drainage system is often overlooked, leaving aside the decision of a major construction problems, but the comfort of home is determined by such seemingly small things.
