Reveal the features of connecting kitchen equipment to engineering communications.
Installing a modern kitchen, in addition to the furniture assembly, suggests connection to the water supply and sewage systems of some devices, namely: dishwasher and washing machine, water purification filter, chopper and washing. Despite the seeming simplicity, the connection of equipment and sanitary priborov causes many questions.

Connecting the kitchen
Connection scheme
After buying a kitchen, it becomes necessary to connect equipment to engineering networks. Usually, kitchen furniture suppliers are connected to the instruments to in advance organized points of water intake and sewage, and the problem of pipe gasket to these points falls on the shoulders of the customer.
Serious Suppliers provide each client technical documentation for the kitchen, which indicates the coordinates of the places of connecting equipment and Santehpribors. According to this project, the pipe layout is performed. It must be remembered that all sizes given in the document are given from the chisty marks of the floor and walls. If you ignore these parameters, problems occur when installing the kitchen.
Wiring pipe
Wiring water and sewage is made from the corresponding risers. Often there are general risers for the bathroom and kitchen, but in some series of houses for water supply kitchen, separate risers are organized. The wiring is performed at the initial stage of repair in the process of sanitary work and immediately in all rooms where it is provided.

Installation of shut-off reinforcement
First of all, it is necessary to install shut-off valves on the taps from hot and cold water risers. Best for this purpose are suitable ball valves. High-quality shut-off reinforcement produces Bugatti, Giacomini, ITAP (Italy), Naval (Finland) and many other companies.Installing the filter
The ball valve is necessarily mounted with a coarse water purification filter. Such filters are divided into mesh and cartridges. The filtration degree in the cartridge filter may be higher than that of the mesh, however, the cartridges require periodic replacement. Filters are recommended to purchase with the size of the cells of the filter element not more than 100 microns.
Mesh models produce such firms as RBM, Bugatti, Tiemme (Italy), Honeywell Braukmann (USA- Germany), Syr (Germany). Cartridge filters manufacture usfilter (USA), Atlas Filter (Italy), etc.
Installation of the reducing valve
If the pressure in the water supply system exceeds 5 atm, it will be necessary to install a reduction valve, or a pressure reducer that is located after the filter. The valve will prevent the vehicle outflow due to excessively high pressure in the system, besides, the installation of devices on both risers will allow you to set the same pressure in the apartment highways. Miscellaneous pressure causes inconvenience when using mixers (it is difficult to adjust the necessary temperature and water pressure), and may also cause noise and vibration in pipelines.For the work of Santechniborov and household appliances, the pressure of 3-4 atm is considered optimal. To save space in the plumbing cabinet, it is better to establish combined filters with a built-in pressure gearbox. Reduction valves produce RBM, Honeywell Braukmann, Tiemme, etc.
Mounting counters
The meter allows you to significantly save on the payment of bills for water supply. In order for the calculation to be made according to the meter readings, it must be registered in DEZ.
Currently, a collector (fan) layout of water supply systems, eliminating pressure drop at various points of water resistance, was quite widespread. Its use allows you to block the flow of water on any of the consumers without affecting the work of others. The wiring along the collector scheme involves the gasket to each point of water consumption of a separate pipe, which significantly increases the reliability of the entire system. Today, polymer and metal-polymer pipes are used for this purpose.
Modern pipeline systems
Polymer and metal-polymer pipes have practically disapplied traditional steel and copper products from this area thanks to a number of advantages. Such pipelines are not subject to corrosion, their inner layer is resistant to abrasion and does not contribute to the accumulation of deposits. Due to this, the diameter of the pipe cross section is kept constant during its service life (at least 50 years). An important property is a high degree of pipe hygienicness. In this case, the installation of such pipes is simple and does not require much time.Metal-polymer pipes
The most common type of pipes used in water supply systems is metal-polymer. They consist of an inner layer, usually made of stitched (PEX) or heat-resistant (PE-RT) polyethylene, aluminum shell, an external protective layer and bonding layers based on adhesive compositions.
The advantages of pipes, besides excellent performance properties (10 atm operating pressure at the maximum temperature of 95 degrees), include a small coefficient of temperature expansion, as well as the high stability of the shape specified during installation (the pipe is not inflicted spontaneously). For metal-polymer pipes, a wide range of fittings is produced. There are crimp, or compression, fittings and press fittings (mounted using press clamps).
Metal-polymer pipes produce many companies, such as Oventrop (Germany) under the trademark COPIPE, VALSIR (Italy; PEXAL Pipeline), PRANDELLI (Italy; Multirama products), Geberit (Switzerland), Altais, Metal Falimer (Russia).
Polypropylene pipes
Polypropylene tubes are often used. The cooker of their compounds with fittings is based on diffusion of materials: performed by contact thermal welding of parts into a slur, the compounds are a single structure and do not understand. The reliability of them is very high.
Polypropylene tubes are produced both for cold and hot water supply. In the latter case, to reduce the coefficient of linear expansion, the product is supplied with a reinforcing layer of aluminum tape or fiberglass layer. Such pipes are record holder recorders: working pressure up to 25 atm at temperatures up to 95 degrees.
Such products in our country are supplied by Aquatherm, Wefatherm (Germany), Dizayn Group, Pilsa (Turkey), Ekoplastik (Czech Republic) Idre. Polypropylene pipes and Russian manufacturers, such as buildingPolymerprogram, are manufactured.
Pipes from polyethylene
Pipes made of crosslied or heat-resistant polyethylene are not less popular. Operating properties of products (operating pressure of 6 atm at a temperature of up to 95 degrees) allow them to be used for cold, and for hot water supply.Such products are published by Wirsbo (Sweden), Rehau (Germany), Kan-Term (Poland), Uponor (Finland), Revel (Czech Republic), Vantubo, Birpex (Russia) and others.
Pipes from chlorinated PVC
In Russia, pipes made of chlorinated PVC are also common. Connections of pipes with fittings are usually carried out by gluing. The advantages can be classified a very low linear expansion coefficient and non-combustible material. We mainly have products of American companies (Genova Products, etc.).
Sewerage
As a rule, the sewer (horizontal removal) of the kitchen is connected directly to the riser. For this purpose, sewer pipes with a diameter of 40 or 50 mm are used. Typically, pipes are hidden, observing the minimum bias in the direction of the riser of at least 2.5 and avoiding sharp turns (for example, 2 decodes of 45) are made for 90 degrees).
In order for the unpleasant smell from the sewage to penetrate the room, hydroplays (siphons) are installed at the site of connecting to the SantechPribar. Connecting to the system of dishwasher or washing machine is performed either through the siphon of the kitchen sink, or through a special valve immediately to the sewer allure. Also, the sewage waste and water purification filters operating on the principle of reverse osmosis are connected to the sewage system.
Polypropylene tubes are optimal for laying sewage networks. Compared to common products from PVC, they are high temperatures (up to 95 degrees) and the effects of most solvents, and their cost is only a little higher. Polypropylene pipes for sewage systems and fittings to them are issued by Valsir (Italy), Wavin (Denmark), Synikon, Politek (Russia).
Connecting the kitchen
After finishing the room and assembling furniture, it is processed to connect equipment to engineering communications. Here, as for the wiring, the following materials and components are used: lock fittings, fittings, eyelid, siphons, etc. Conventional flexible eyeliners have a limited service life (not more than 10 years), after which it is better to replace them. For this reason, some firms prefer to use or copper tubes with appropriate fittings instead, or flexible liners of a bellows type of stainless steel (service life - at least 50 years).
The dishwasher is connected to the water supply system by means of a flexible lining supplied. Keep in mind that many household appliances manufacturers strongly recommend increasing the eyeliner equipped with an Aquastop device. To the sewage system, the machine is connected only through the siphon. Otherwise, smells from the sewage network will penetrate it. When connecting through the siphon during the operation of the machine, there is sometimes boulurs in the sink, this can be avoided by connecting the device through a special valve.
Installation of food waste chopper does not create special problems, usually it comes with all components for installation.
Reverse osmosis filter is mounted mainly under the sink. All its components are connected to each other with special styled polyethylene tubes supplied in the kit. The reverse osmosis filtering system necessarily includes a storage tank, the location of which under the sink is capable of creating certain difficulties. For their overcoming, it is possible, for example, to separately purchase the tube of the required length and make a drive beyond the kitchen. Also, with the help of an additional tube, a refrigerator equipped with an ice generator can be connected to the filter. Any such filter has a tap for feeding drinking water, which is installed on the sink or near it on the table top.
