With an independent water drain organization at the house, complex measures are to be implemented, thanks to which the adjacent territory will be protected and preserved in integrity. The rules for installing the gutter are simple: you will have to calculate the diameter of the pipes, selecting a silent trough material, and installing the system under the necessary slope, organizing a catchment and water disposal.

On the need to install a drain
It is known that an attractive view of the gutter system is adorned by the house, and technologically correctly selected gutter elements and located troughs provide protection from bad weather.
Moreover, the installation of drainage systems, including the details and dimensions of downpipes, are regulated and implemented in accordance with the requirements of SNiP RK 4.01-41-2006 *. Correctly carried out by hand, the drainage installation should ideally ensure the safety of the supporting structures and the foundation of the house from the strength of the water.
When choosing a drainage system, it is recommended to take into account the climatic conditions and location of the house, taking into account the periodicity of precipitation, the geometric features of the roof and the material of its manufacture, the angle of inclination of the slope.
Elements of a drain or how the system works
The technology of assembly and installation of the drainage system on the house represents a sequence of steps: "fixing the mounting elements" - "gutter and funnel installation" - "drainage organization" - "riser and elbow installation".
Gutter system from the serial manufacturer consists of the following elements:
• catchments and funnels
• connecting risers and elbows
• Fasteners
• Final drains.
The main receiver of water are gutters, which are attached either to the frontal board of the roof, or installed on the lath of the roof and are a problematic part of the drainage system in winter.
Connecting risers and knees are needed to turn the system to the building's façade and ease of attachment.
The connecting elements of the gutter system between the drain pipe and the gutter is a funnel.
Pipes drainage and connecting, as well as a tap provide a drain of water.
The most important element for the safety of the system are couplings and holders.
Helpful Tips
Many people are interested in the question: "Which material is preferable to buy a drain?". Let's say that the elements of the drainage are made:
• of steel roofing δ = 0,63 or 0,7 mm
• from corrosion-resistant materials (plastic with polymer coating, galvanized steel) δ = 0,6-0,75 mm
• from polyvinyl chloride coated with 100 μm of plastisol.
Most developers prefer a drainage system of galvanized steel roofing with a polymer coating with rich RAL color varnish options. It is advisable to install a plastic drainage system in conditions of mild winter, which excludes the likely damage to the building by pieces of ice.
The installation rules and the system assembly algorithm are identical for all roofing materials and assumes a build sequence of the elements. Naturally, for installation and installation of a water drain will require a simple calculation and plan of the system.
Calculation of the drainage system
calculate the slope area and the number of angles
The calculation of the elements of the drainage system begins with the calculation of the area of the roof slope and the number of internal and external angles. Preliminary for the calculation of the drain, determine the size of the diameter and calculate the area.
Based on the results obtained for an area of 60-100 square meters, it is recommended to use a small gutter system, for a ramp area of more than 100 square meters, a large system is chosen. For a small gutter system, the diameter of the round or profile pipes is 90 mm, and the diameter of the chute is 125 mm.
The calculation of the number of angles depends on the configuration of the roofing sheet. For the configuration of a four-pitched roof, the number of corners is: 4 outer corners and 2 internal corners.
calculation of the number of gutters
Preliminarily determine the total length of the eaves. To do this, add the length of the sides of the roof - this will be the total length of the overhang. Then we divide the received sum by the length of one gutter (for reference: the standard gutter length is 3 m). The result is rounded up and gets the required number of gutters for installation.
calculate the number of funnels, connectors and plugs
According to regulatory documents, the length of the gutter for installing one funnel is 10 m, the number of connectors determines each junction of the gutter and corner. Plugs are placed on the end parts of the gutter.
On determining the number of funnels, which are the beginning of the gutter, we calculate the necessary number of risers.
It must be remembered that each riser technologically envelops the overhang of the cornice, therefore it is recommended to provide a tributary bend at the rate of 2 pieces per one riser.
Helpful Tips
There are plenty of gauges for calculating the drainage system. Naturally, you can miss something with a manual calculation. Therefore, the calculation on line on the Internet calculator will graciously help to eliminate inaccuracies and errors.
Rules for self-installation and assembly of the gutter
formation of slope and installation of hooks
For correct installation of the system, it is necessary to organize the slope of the trough, the formation of which is carried out using fasteners with a decrease in the level by 1 pm.
Installation of the drainage system begins with the installation of hooks (holders) of the gutter, which are installed in steps of 0.7 m, forming a slope towards the water receivers.
Installation of the holders can be made in two ways: on a wind or rafter board, install hooks on the crate. To strengthen the drainage structure at the junction of corners and gutters, additional holders are installed. Long hooks are designed for the cornice overhang, short for the end of the rafters and the frontal board.
we install gutters and funnels
The gutter is installed using connecting segments. The funnels are installed in the grooves of the receiving hole of the gutter, the diameters of which must correspond.
gutter assembly
The assembly of the sections of the drainage pipes starts from the top downwards. The lower bell of the link of the element is placed on the upper link of the next element until it stops. Funnels are pre-fixed to the gutter on special clamps and seal the docking points.
To make the correct layout of the system, select the docking configuration.
