Using a Control Relay for Well Pump Operation

	©Copyright Dave Rongey - About Me - Summary: How to Build a Control Circuit to Operate Two Well Pumps – The control circuit could be a 120 or 240 volt protected circuit which may be powered by a transformer which is wired to the primary side of one of the pump circuits or it could be a separate circuit.

A Basic Control Circuit Can Operate Well Pumps

I have two water wells and both produce too little on their own to provide sufficient water for our home.

• They are almost identical in every way, including the submersible pumps and pressure switches.
• Each has its own 220v 30a breaker and circuit.
• Can I combine into one circuit, increase that circuit’s breaker to 60a, wire that single circuit into a single pressure switch, have two circuits come off the pressure switch (one to each pump) and put a 30a breaker on each of these circuits between the single pressure switch and their respective pumps?

Thanks for your electrical wiring question Scott.

How to Build a Control Circuit to Operate Two Well Pumps

Controlling Two Well Pumps

• You can accomplish this simply by using a basic control circuit that would run through the pressure switches and activate 30 amp rated motor controls (larger relays) which would start or stop the pumps.
• The control circuit could be a 120 or 240 volt protected circuit which may be powered by a transformer which is wired to the primary side of one of the pump circuits or it could be a separate circuit.
