Automatic water level control system with alarm Answered

Tank Full Tank Empty what???
A simple circuit like this will alert when the tank is full.

You could make it using a two floats, wires (for the circuit), switches and a power source. You'll also need a pump motor and an audio alarm.
Ping, if you want to know how to connect the various elements of the system.

Is that a question?
Is there a problem with the system?
Do you have enough water?
