Pressure Switch
Well Pump Control Box
Pump controls regulate source production to maintain adequate flow rates and water pressures. Water systems adjust their well control systems to maintain a minimum water pressure as well as an adequate water level in your well pressure tank.
When the pressure switch for your well pressure tank detects low water pressure, the switch closes, which turns on the electricity to the well pump control box. Once the water pressure reaches the pressure switch’s high-pressure limit, the switch opens, turning off the electricity.
Well pumps with a control box have start and run circuits. During start-up, the well pump control will send power to the well pump through the start circuit. Once the well pump reaches operational speed, the control box switches the electrical feed to the run circuit.
Your well pump specialist will need to access your control box for well pump inspections and repairs.
