Review of the plastic drainage system "Technonikol"

Drainage systems "Technonikol", produced in Russia, differ in the material of manufacture and the type of installation. They are used for efficient collection of rain and melt water from the roofs of private houses. They are distinguished by ease of installation, attractive appearance and the presence of special fasteners that reduce the number of holders.

Varieties of drainage systems "Technonikol"

External gutters of this brand are made of 0.5 mm thick steel with a double-sided polymer coating and durable PVC.

The systems consist of several elements that fit perfectly together:

• gutters;
• pipe sections;
• connecting elements - corners and couplings;
• drain funnels with protective grids;
• fasteners.

The length of the Technonikol system gutter is three meters. Width - 12.5 cm. The size of drain pipes with a cross section of 8 cm is also three meters.

The manufacturer offers elements for internal plumbing made of plastic. These are funnels of a special type, designed to collect and further drain water on flat roofs covered with roll materials. They are installed in places with the lowest height marks. Such devices can last longer than a quarter of a century. Equipped with slamming foliage catchers, which are placed on the water intake bowl. If the roof is not insulated, electric heating equipment is possible.

Advantages and disadvantages

The common advantage of plastic and metal structures is their ease of assembly and ergonomics. The design of gutters is universal and suitable for any style and architectural solutions of private houses. The connection of the parts is hermetically sealed: all elements are equipped with rubber seals and latches to avoid leaks.

The roundness of the outer corner and the funnel, which exactly repeats the gutter shape, give aesthetics and prevent the accumulation of debris and snow. Such devices can be used in any climatic zone - they can withstand temperatures from minus 50 to plus 50 degrees.

The plus is the varied color variation of the gutters. In the catalogs of the manufacturer or its official representatives, you can choose the desired shade to match the roof, facade decoration or site fencing.

The difference between Technonikol systems and gutter models of other brands is that the number of connecting and fastening parts is minimized.

Other advantages are based on the characteristics of the materials used to manufacture. Due to the polymer layer, metal-plastic structures are difficult to corrode, they are strong and durable. The parts are made in such a way that it is extremely difficult to damage the coating during assembly. The inner steel layer makes the structure resistant to mechanical damage.

The advantages of a plastic drainage device include:

• the impossibility of corrosive changes - there is nothing to rust;
• resistance to ultraviolet radiation and chemically active media;
• light weight, which simplifies installation;
• budget cost.

The light weight makes it much easier to carry out any repair work or change a part that has become unusable. The system easily adapts to any roof shape and size thanks to a wide range of accessories and additional elements.

PVC products are plastic. They do not crack under the influence of water pressure or temperature changes, but stretch and then take their previous shape.Silicone sealants can be used to increase the watertightness of the joints when assembling plastic parts.

The disadvantages of the plastic system include damage to the elements with a direct impact. But this damage is quite difficult to do.

Metal-plastic parts are stronger, but they have their drawbacks. During the descent of water, the sound of a droplet fraction occurs, as in heavy rain.

Due to the not too large cross-section, the pipes may not cope with the abundance of precipitation, therefore, this system is rather weak for tropical showers. For Russian conditions, this diameter is sufficient.

The company gives a guarantee for the goods for a period of 15 years, even under intense loads. In fact, the device will last at least twice as long, provided that all operating rules are followed, and the installation was carried out correctly.

Installation rules and stages

It is not too difficult to mount the structure if you follow the following guidelines:

• Focus on sealing the joints between the funnel, gutter and pipe.
• When tracing a complex roof, use connectors with different angles of the sweep.
• Be sure to align the center of the gutter with the edge of the roof, and set its inner side 50–80 mm from the wall of the house.
• Slope the gutter about 3-5 degrees.
• Fasten the brackets at a distance of half a meter from each other.
• Prepare safety equipment, tools and carefully study the instructions from the manufacturer.

Before proceeding with the installation of the spillway, a frontal board is installed. When assembling the drainage system using funnels as load-bearing elements, the installation begins with their fastening. In another situation, first fix the holders on the eaves board, which are necessary to support the gutter.

Installation instructions for both metal and polymer gutter systems "Technonikol" differ little. The assembly is carried out in stages:

1. Conduct an inspection of the building to identify where the weir details will be located. At this stage, the main thing is to calculate the length of the system and the exact dimensions of the pipes, as well as their number.
2. Determine the location for the main drain and, 15 cm away from the wall, install the first holder. Fix the bracket in the corners of the cornice and reinforce it with twine. Fasteners are mounted from the inside to the outer edge. The latches must be snapped in to the end, otherwise the structural integrity will be violated.
3. Beginning with the drain funnel, install the gutters into the brackets. Their ends are inserted into the funnels from the inside out until they click. Use couplings to connect them together.
4. Begin installing the drain pipes. The first one goes to the main funnel. Fasten the pipe elements securely using clamps.

After all items are in place, fit the outer plug and protective grilles to prevent clogging by leaves, branches and debris.

The cost of components

The price for plastic and metal drainage systems "Technonikol" is formed depending on the following indicators:

• roof area;
• the complexity of the geometry and size of the building;
• the required number of elements used;
• the size of the roof overhang above the wall;
• the amount of indentation for the installation of the water intake.

You can see the prices on the manufacturer's website. Plastic parts will come out cheaper: a funnel costs about 200 rubles, a pipe elbow - 130 rubles, and the pipe itself - 340 rubles. The spillway will cost 130 rubles, fastening and damping parts cost in the range of 50-100 rubles.

The cost of the system will increase due to professional installation if gutters are installed by a hired team.

If you have never held tools in your hands, it is worth investing in specialists. Indeed, its service life directly depends on the quality of assembly and fixing of the drain.
