A wiring diagram is a simplified traditional photographic representation of an electric circuit. Water pressure switches in well systems control the amount of water pumped to the systems storage tank.

Wiring a well pressure switch. It reveals the parts of the circuit as simplified forms and the power as well as signal connections between the tools. To replace the two wire pump. Pressure switches are used on water pumps for the accurate control of the pump as it produces pressurized water. However with the pressure switch the pump can be adjusted to turn on and off at predetermined settings to control the pump and subsequent pressure. The diagrams for both the two and three wire pumps can be downloaded using adobe. It shows the components of the circuit as streamlined shapes and also the power and also signal links in between the devices.
Flip the breaker to the pump switch and check it with a voltage sniffer to make sure its off. Without the use of the switch the water pump would always be on or off. Loosen all of the terminal screws enough to place the wires under them. Then disconnect the wiring photo 1. Collection of well pump pressure switch wiring diagram. A wiring diagram is a streamlined standard photographic representation of an electric circuit.
After determining the voltage is zero disconnect the motor wires directly from the pressure switch box m1 and m2. Wrap the pipe threads with teflon tape and reassemble. Close the valve from the pressure tank to the house. Locate the uninsulated ground lug or terminal on the housing of the well pressure switch. Collection of well pump pressure switch wiring diagram. Then drain the pressure tank.
As the tank is filled the water pressure increases within it. Check both sides of the switch to confirm zero voltage and you are ready to remove the pump. Replace a two wire pump. In this video we show you the best way to a pressure switch for 115v and 230v pumps. Remove the cover from the well pressure switch and locate the four terminal screws in a row. This method will work for any pump that runs directly off of a pressure switch including jet pumps well.
When the tank reaches its peak pressure typically at 60 pounds per square inch the switch cuts the electrical power to the water pump. Next remove the old switch photo 2 and gauge photo 3.
