When repairing an apartment, it is often necessary to hide the plumbing riser, providing access to lock valves and water meters. Solve this task is easy - the main thing is to know which materials and designs to use

What option to choose?
In any apartment there are sanitary risers (risers) with water pipes and sewer pipes. As a rule, it is hidden, since SNiP 41-01-2003 prescribes to lay pipelines from polymer pipes "behind screens, in strangers, mines and canals." But when repairing old screens and plumbing cabinets usually dismantle. How to replace them?
In the standard Santechkabina, the riser is located behind a monolithic gypsum partition, asbestos-cement or gypsumless sheet. The wall is provided by the opening, closed by a lining door from laminated or painted chipboard. The design looks not too aesthetically, and it is difficult to improve - at least because the sloppy door will not stand the mass of tiled cladding. Theoretically, it is possible to install in the existing work of the modern hatch-invisible, but in practice this solution is inappropriate, as it will have to order an expensive non-standard product. It is easier to dismantle the partition and build a new one - frame.
The frame is collected from steel galvanized profiles: first to the side walls, the floor and the ceiling are fixed profiles, forming a closed frame, then enhance the design with horizontal jumpers, and if necessary - and racks. Moisture-resistant gypsum fiber and glass-proof sheets, as well as cement plates with a thickness of 10 mm are suitable for the skin. To isolate the sound flowing in water pipes and ensure the strength necessary to install an audit hatch, a two-layer casing will be required. In the partition, it should be provided with a capacity of 400/500/600 × × 600/800/1200 mm, placing it so that it is convenient to take the indications of the counters and use the locking reinforcement.

During the construction of new walls of the bathroom after the demolition of Santekhkabina and the arrangement of the apartments of free planning (where the cab is missing) the choice of materials for the mine The standing is limited only by the requirements of strength and moisture resistance. Let's say, you can use hydrophobized puzzle plates (PGP) or lightly invoked ceramic blocks. Nevertheless, the frame design remains the most popular - due to the low thickness of the walls and the speed of installation, and also because it allows you to install mounted plumbing easily.

After mounting the plumbing and finishing of the room to access the tank mechanism use the lung panel of a flush, which can be made of plastic, metal or tinted glass. Photo: Geberit.
A revision hatch for the mine is better to choose in advance. The installation of products of each company and the line has its own characteristics that it is necessary to take into account during the construction of the mine, and part of the models are easier to install before the framework of the framework. The overwhelming majority of hatches are designed for cladding tiles and mounting in one plane with the wall. The cheapest (from 1500 rubles) will cost a removable door fixed in the steel frame with spring rings. However, such a hatch is inconvenient to use, and the facing is easily damaged when opening-closing.
Much greater comfort provide retractable invisible hatches. They are offered by the practice of "Practice", "Colosseum Technologies", "RUSVENT MSK", "Sun-Group" and others; The price of 400 × 600 mm products starts from 3 thousand rubles. The design consists of a metal frame, doors, a lever-hinge opening mechanism and a latch lock. The spring snatch is more convenient than magnetic, as unlocking when pressed without suction cup or roofing. Luke needs to be put forward from the side of themselves and open either away to the side - depending on the type of mechanism. The basis of the structure can be made of aluminum or galvanized steel. Note that the corrosion durability of the galvanized is quite enough for a wall hatch (aluminum is necessary only in floor models), so it is hardly overpaying.
How to lower the noise level?
The noise from the water in the sewer pipes can penetrate the walls of the mine and the door of the audit hatch. Meanwhile, a modern approach to repair assumes that silence must reign in the bathroom and neighboring premises. (By the way, that is why Santechpribers are forbidden to mount on the walls overlooking the rooms.) It is advisable to replace regular pipes for special noise absorbing, for example, Rehau Raupiano Plus. With the same thickness of the walls as in conventional sewer, noise absorbing products have a greater soundproofing ability due to mineral additives in the material and vibrational compounds with special clamps. Note that the effectiveness of such systems is significantly increased if they are installed throughout the building.Practical advice
- Do not save, trying to make a sanitary hatch on your own or buying a cheap, but inconvenient removable door.
- It is advisable to buy an audit hatch before the construction of a masking structure.
- For a long service, the carrying capacity of the hatch loops should exceed a mass of the door with a finish by 40-50%.
- Do not refuse such an option as a loop with three-dimensional adjustment; Without it, it is difficult to achieve a dense adjacent of the door and a smooth gap around the perimeter of the hatch.
Manufacturers offer pipes of different lengths and diameters, as well as fittings for them. Photho: Rehau
The loop mechanism of sanitary hatches is able to withstand the load in hundreds of kilograms-forces and is designed for tens of thousands of opening / closing cycles. Photo: "Practice"
