Mechanical water filters are devices that prevent the penetration of foreign mechanical bodies, which are present in tap water in our household network. They should not be confused with the filters for drinking water. These devices are completely different tasks. Mechanical cleaning filter does not protect you from the dissolved chemical elements and compounds and not get rid of bacteria, but will prevent faucets and appliances from premature failure. Typically, the cause of breakdowns of household appliances and fittings in the house - it is the poor quality of tap water. The set is insoluble in it in large quantities of solid particles leads to a rapid deterioration of taps and, hence, to frequent their repair. This is especially true gentle imported bathroom. Choosing the right water filter - it is half the battle. However, this choice should be made depending on the tasks to be solved and, naturally, on the financial capacity. First of all, should decide on what pipe you need to install a filter: horizontally or vertically - not all models of filters can be placed in any position. Regardless of the type of filter, its bulb should be strong enough to withstand water pressure. Flask for hot and cold water are made of different materials. Flask under cold water is made of shockproof synthetic material such as plexiglass, for hot water - made of bronze or reinforced nylon as the bulb should be much stronger. Brass bulb are equally good and hot and cold water. Normal water pressure should not exceed 6 bar, but in our water supply networks often arises unpleasant thing as a hammer - a multiple, a sharp increase in pressure. Therefore, the quality bulb must withstand the pressure of 16-25 bar. Maximum pressure filter must be specified on the case and the passport unit. Many filters are equipped with pressure reducing valve, the device, decreasing the water pressure at the entrance to the apartment tower. Installing the filter - it is quite simple, it can be trusted with any plumbing. In the tube, serves hot and cold water in your apartment, embedded filter, which is a flask, from which depart the input and output connections. Now all the water entering the apartment, passing through such a device. The choice of mechanical cleaning filter water is dependent on the specific requirements and conditions of use are cartridge filters and rinse. Cartridge filter is a collapsible flask, into which is inserted into the filter element replaceable cartridge. Each time a cartridge is clogged and it needs to be washed, you must disable and dismantle the water filter. In turn, cartridges can be divided into cellular and filament. Net cartridge - a metal cylinder with small holes resembling a sieve. Filtering ability of it - from 20 to 100 microns. The smaller the hole, so more particles will be delayed filter. Metallic cartridges can be used for both cold and hot water, they are fairly easy to wash and reuse. Such filters are installed as off cold and hot water is the maximum operating temperature - 1200S, maximum working pressure of 20 bar. Main advantages: low cost, simplicity of design, installation versatility (ability to install on vertical and horizontal distance pipelines), wide operating temperature range, the lack of necessary supplies, etc. The disadvantages include: the prevention of ingress into the system only large solids ( larger than 500 microns), the need to dismantle the plug and break the cycle of water delivery and filtration to clean the filter mesh. Used for hot and cold water supply in apartments, offices, suburban homes and other filament coil cartridge is a nylon filament or a reinforced nylon mesh wound around the tube. The higher the density of the cord-winding, the higher the filtering ability of the filter. In filament cartridges, it can be 1 micron. Unfortunately, they can not use hot water because of its impact yarn swells, and filtering properties deteriorate. In addition, they can not be reused because it can not be washed. In cases where you do not want every time to disassemble the filter for cleaning, you can get free of this shortcoming, but more expensive, washable filter. It also consists of the flask and the filter element, but cleaning it is not necessary to disassemble. In contrast to the cartridge, washing the filter has a drain hole, which usually connects directly to the sewer. Thus, you can periodically pour the dirt accumulated in the sump. Fairly easy to determine how clogged the filter element: if the water flow decreases, so it's time to clean the filter. More efficient and user-friendly filters with the function of the backwash. There are two types of backwash - manual and automatic. In the first case, you must own at regular intervals to perform washing of the filter. Usually, this should be reversed, depending on the construction, crane, or the filter cap. Then the water out of the total water supply comes from the reverse side of the filter mesh, washed precipitated in her elements and then merges into the sewer. Ideally, the filter backwash shall be connected to the sewer. In the absence of such a possibility, you can use a separate tank of at least 10-12 liters. In any case, wash the filter should be conducted periodically. With what frequency it is - hard to tell, because too much depends on the degree of contamination of incoming water. If you do not want to do this dirty work and not low on money, buy filters with automatic cleaning. Filters with automatic backwash is very easy to operate. At the time of maximum pollution grid or a set time on the washer automatically cleaning the filter element. Determination of the maximum contamination is based on the measurement of pressure. When the pressure loss reaches a certain size, mode is flushing. Customize intervals flushing depends on the quality of water, determined by the content in it of impurities. Usually sufficient to clean the filters once or twice a month. Performance of mechanical cleaning filter depends on the size of flanges (bandwidth pipes), the cell size of the filter element and hydraulic losses. With the current deterioration of water pipes of the system to do without mechanical cleaning filter practically impossible. The alternative can only be a permanent repair water networks.
