What is the difference between a washbasin and a washbasin? When should I use the washbasin?

Personally, public buildings are not used by one person. From the health point of view, it is washbasin, running water to wash your face and hands. After the family receives water from the washbasin, they can store the water in the washbasin for washing their faces and hands, so as to save water.

The washbasin just washes hands; Wash your hands and face in the washbasin;

Residential buildings are calculated according to washbasins, and general public offices are calculated according to washbasins;

Hospital outpatient service is calculated according to washbasin; The inpatient department of the hospital has to be counted according to the washbasin.

The drainage equivalent of washbasin is different from that of washbasin. For public buildings, consider washbasins; For residential buildings, the washbasin with plug is considered to have a relatively large primary displacement; For washbasins without plugs, direct drainage has little overall impact.

Laundry balls are mostly used in public buildings, only cold water pipes. Laundry balls are mostly used in residential buildings. See atlas 09S304 for hot and cold water pipes.
