Working principle (automatic water injection tower):
The water level rises:
When the water level is lower than the "low level", the water pump starts to supply water to the water tower; when the water level is higher than the "high level", the water pump stops water supply.
The water level drops:
When the water level is lower than the "high level", the water pump does not work and the water level continues to drop. When the water level is lower than the "low water level", the water pump starts to supply water to the water tower.
Working principle (automatic pumping of water tower):
Contrary to "automatic filling of water tower"
