When the water pump is in normal operation, if the water level is low, it is obvious that the water is easily to be drawn up. If you adopt this pressure switch, when the pressure is below 10PSI, it can automatically cut out, which can protect the electric machinery of the water pump from being destroyed. And when there is water, the switch can help the pump to operate again. When the pump is to operate, please adjust the metal spanner on the right till the pump works.
