Federal Law No. 416 “On Water Supply and Sanitation” regulates the quality of drinking water, the safety of effluents discharged into natural reservoirs or soil, the rules for the supply of hot and cold water, and the accounting for the amount of its consumption. The law is amended annually, which suppliers and subscribers must consider.

Flexible pipes for water supply are used when laying a trunk in hard-to-reach places, as well as when installing a warm floor, in a gas supply and air conditioning system. The material should be selected depending on the operating conditions. It can be polymers, metal, steel.

Water pipes 32 mm, as a rule, are used for internal wiring of the highway. Technical characteristics and the method of joining depends on the material: steel, metal-plastic, polypropylene, polyethylene, polyvinyl chloride.

Users of central water supply are required to install water metering devices. Counters are mechanical, pulsed, ultrasonic, vortex, electromagnetic. After installation, an employee of the management company seals the device and registers the initial readings.

The quality control of drinking water is regulated by SanPiN. Epidemiological and radiation safety, chemical composition, organoleptic indicators should be regularly checked. In case of any violations of the norms, the water supply from this source should be stopped.

The site for entering the water supply into the building must be designed before construction begins under the non-residential premises. It must be protected from mechanical damage and insulated. For a free drain, it is necessary to provide a bias towards the external highway.

The rules for using water supply and sewerage systems are regulated by RF Government Decree No. 167. They stipulate the supplier’s obligations to provide apartments with clean water and the subscriber’s obligation to pay for the services provided according to the tariffs. The operating instructions and possible problems are also indicated.

The cold water supply scheme of a residential building can be sequential, collector or combined. The first is used most often, it is easy to install and economical, however, difficulties arise during repair. The collector circuit is easy to maintain, but it is quite expensive.

To ensure that the water supply system runs smoothly at any time of the year, a station should be installed to supply water to a private house. The equipment will provide a constant pressure, will allow to raise a column of water to the second floor and higher if necessary. The main thing is to choose the right place and correctly connect the unit.

The scheme of water consumption and sanitation is drawn up before laying the foundation of buildings.All slopes, turns and intersections must be taken into account in order to prevent breakthroughs, blockages, freezing of pipes, to ensure uninterrupted water supply and drainage. Installation and operation are regulated by regulatory documents.

Booster pumps for cold water supply are necessary if the water pressure has become too weak due to insufficient pressure in the pipeline. Models differ in the principle of operation, type and method of installation, as well as the main parameters: power, performance, throughput.
