 GENERAL INSTRUCTIONS  

The initial data for the development of working drawings  are architectural, construction and technological drawings.  

The norms of water consumption and the calculation of water supply and sewerage systems are made according to SNiP 2.04.01-85 *. installation of the water supply system, sewerage should be carried out in accordance with the chapters of SNiP 3.05.01-85 and CH 478-80.

    Production of sanitary and technical works, testing and acceptance into operation should be carried out in accordance with SNiP 3.05.01-85 and CH 478-80.

    COLD WATER PIPE.  

The source of water supply is the projected on-site networks.  The project provides for one input with a diameter of ∅40 with the installation of a water meter for household needs. To supply water to the required head in the network above the meter. 0.000, requires the installation of a household water pump with parameters Q=3.0 m³/h, H=25,5 m, N=0.55-0,75 kW

Pump (Calpeda MGPM 403) Water supply network is installed from reinforced-plastic pipes.

    HOT WATER SUPPLY  

Hot water supply is decentralized. For the preparation of hot water there are electric water heaters of the company ARISTON. The system is adopted with lower piping, dead-end.

With a hidden gasket, provide a hatch for access to the fittings.
