Working principle: 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 supplying water.
Water level reduction: When the water level is lower than the ``High level``, the water pump does not work and the water level continues to decrease. When the water level is lower than the ``Low water level``, the water pump starts to supply water to the water tower.
