Certificates and instructions Prices and catalogs WATER SUPPLY Water sources The water supply for a home consists of a water source, water supply system, filters and plumbing fixtures in the home. The best source of water is an artesian well with a depth of 100 m, but it is very difficult and expensive to obtain a permit for the construction of such a well. Therefore, as a rule, one such well is drilled for the whole village. Then the water is accumulated in the water tower and supplied to the plots (houses) through the summer (aboveground) or normal (underground) water supply. Decentralized water supply system. Decentralized water supply systems (Fig. 1) consist of individual water intake structures (wells, hood chambers, springs, wells), external (if the water intake is outside a residential building) and internal pipelines, sanitary devices and fittings, a water-pressure or hydropneumatic tank. It is possible to arrange a common water intake structure for 2-3 neighboring houses. The site for the water intake device should be selected in an unpolluted place, upstream of the groundwater flow. Water intakes should be removed from possible sources of pollution (latrines, cesspools, stockyards, landfills, burial sites, etc.) at a distance of at least 50 m. Water intakes should be located on a dry elevated plot of land. General information about the internal water supply. Internal utility and drinking water supply is arranged in all residential buildings with a sewerage system. In residential buildings, you can arrange a combined utility and drinking and fire-fighting water supply system or two separate water supply systems. The internal pipeline network is divided into main pipelines, risers and connections. The main pipelines of the internal water supply, laid at the bottom or top of the building, serve as distribution lines for supplying water to the desired sections of the pipeline or risers. Risers - vertical sections of the distribution pipeline through which water is supplied to the piping to sanitary appliances. Cold water supply systems. The internal water supply system consists of the following elements: entering the water supply system into the building, distributing pipelines, booster installations, which include increasing pumping, water supply tanks and reservoirs located inside the building. Depending on the water supply scheme to the water points inside the building, the following systems are arranged Connecting water fittings. В пониженных местах магистрального трубопровода ставят спускные тройники. Повороты трубопровода под углом устраивают с помощью фитингов или изогнутых труб. В дымовых и вентиляционных каналах прокладка водопроводных труб не допускается. Чтобы обеспечить нормальную эксплуатацию, на внутреннем водопроводе устанавливают запорную арматуру вентильного типа: на каждом вводе — для отключения здания; на кольцевой разводящей сети — для отключения отдельных участков, но не более чем полукольца; у основания пожарных стояков; на ответвлениях, питающих пять и более точек; на подводках к смывным бачкам, смывным кранам, водонагревательным колонкам к душам и умывальникам; перед наружными поливочными кранами; перед приборами, аппаратами и агрегатами специального назначения; на всех ответвлениях от магистральных линий водопровода. Recommendations for the installation of cold water pipelines. For internal cold water pipelines, plastic pipes and fittings made of polyethylene, polypropylene, polyvinyl chloride, polybutylene, metal-polymer, fiberglass and other plastic materials are used - for all water supply networks, except for a separate fire-fighting water supply network. For all internal water supply networks, it is allowed to use copper, bronze and brass pipes, fittings, as well as steel pipes with an internal protective zinc coating against corrosion.
