BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Monitoring level of water inside tank or other water sources associated with buildings, houses, and other apartments is challenging as checking threshold value of the water level frequently is problematic. Also, entity cannot turn on switch of electric motor without knowing the water level inside the tank. As a result, due to empty tank, air gets filled inside water pipes which need to be explicitly squeezed out from the water pipes with the help of pressure pumps. The entity should be aware about the water level of the tank, and accordingly can turn the switch for motor.

[0005] There is a need to overcome above mentioned problems of prior art by bringing a solution that helps entity in identifying different water level inside the tank with help of different alert units and also removes air from water pipes automatically.
