The layout of water pumps meets the principle of spacing and compactness, and takes expansion and development into consideration.
High water tank
Effective volume
Determine the amount of water adjusted according to daily life
The height should ensure the required outflow head at the most unfavorable water distribution point
The water tank is generally arranged on the top floor or in the stuffy roof, and a cover plate should be installed. There should be ventilation holes in the cover plate. The net height of the room where the water tank is installed should not be less than 2.2 meters. The load-bearing structure where the water tank is installed should be non-combustible. The indoor temperature should not be lower than 5 degrees Celsius
Pipe layout and laying
Introduction pipe
When water is used uniformly, the house is introduced from the center
water meter node
Buildings that must separately calculate water volume should install water meters on the inlet pipes or on the main branch pipes of each household.
Water meter nodes can be located in outdoor water meter wells in warm areas of my country, and the wells are more than 2 meters away from the exterior wall of the building. In cold areas, they are often installed in indoor heating rooms.
