Using a Control Relay for Well Pump Operation
How to Build a Control Circuit to Operate Two Well Pumps: I have two water wells and both produce too little on their own to provide sufficient water for our home.
Basic Control Circuit to Operate Well Pumps
Electrical Question: 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 type of control for two well pumps 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.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
