Water pressure switches in well systems control the amount of water pumped to the systems storage tank. 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.

Water Pump Wiring Troubleshooting Amp Repair Pump Wiring Diagrams
Well pump pressure switch wiring diagram. A wiring diagram is a streamlined standard photographic representation of an electric circuit. Collection of well pump pressure switch wiring diagram. It reveals the parts of the circuit as simplified forms and the power as well as signal connections between the tools. Well pump pressure switch adjustment. Step 4 locate the bare copper wire or ground wire from both groups of wires and connect them to the ground lug or terminal on the well pressure switch housing. Insert the wires from the well or pump the wires marked from pump or well in the same manner.
Your well pump gets its marching orders from the switch mounted on the pressure tank. As the tank is filled the water pressure increases within it. A wiring diagram is a simplified traditional photographic representation of an electric circuit. In this video we show you the best way to a pressure switch for 115v and 230v pumps. When the switch acts up and they all do eventually youll see all kinds of strange behavior pump wont turn on turns on erratically or wont shut off. 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. Pressure switches are used on water pumps for the accurate control of the pump as it produces pressurized water. Replacing the pressure switch is cheap and takes only about. It shows the components of the circuit as streamlined shapes and also the power and also signal links in between the devices. Without the use of the switch the water pump would always be on or off.
