How does a pressure switch work on a well pump?
Pressure switches rely on water pressure to do all the work. The change in pressure that activates the switch is provided via the water from the well. The pressure moves up through the diaphragm which presses against a piston and spring, which in turn opens or closes the contacts.

Does the pressure switch go before or after the pressure tank?
Never start with a larger size for any distance and then change over to a smaller size pipe before the tank. Always have at least 12" of pipe from the main line to the tank. Install the pressure switch tap on a tee at the end of this length of pipe as close to the tank as possible.
Can you run a well pump without a pressure switch?
Can You Run A Well Pump Without A Pressure Switch? If you do not have a pressure tank, your well pump will not stop running or switching on and off. A well pump can overheat, burn out, or at the very least shorten its useful life if this condition is not addressed.

Can you wire a well pump backwards?
A common myth is that in reverse rotation, the pump causes backward flow, that is, IN the discharge and OUT the suction. In reality, a pump operating in reverse rotation because of wiring or phase change will pump in the normal direction. Now, it won't pump very well. Its flow will be reduced, as will its head.
What is the difference between a 2 wire and a 3 wire well pump?
The main difference between 2 wire and 3 wire well pumps is characterized by where the starting components for the motor are located. Three wire well pumps house the starting components (starting capacitors, running capacitors, relays, and thermal overloads) in a control box or panel.

How do you reset the pressure switch on a well pump?
Hold the reset lever in the start position until the pressure builds up and the gauge reads over 40 PSI; then let it return to the AUTO position. The pump should now run on its own and continue until the pressure reaches the cut out setting, (usually between 50 - 60 PSI), and then shut off.
What is good water pressure for a well?
40 psi to 60 psiWhat Is Ideal Water Pressure for a Well? The best water pressure for a well is 40 psi to 60 psi. Having low water pressure can be caused by many different reasons, but there are just as many ways to improve it. If your well is operating at any less, call a plumber.
How often should you service your water well?
An annual well maintenance check, including a bacterial test, is recommended. Any source of drinking water should be checked any time there is a change in taste, odor or appearance, or anytime a water supply system is serviced.

What is a pressure switch?
The Pressure Switch tells the pump that delivers water to your home when to turn on and off. When the pressure in the system drops to a preset low setting the pump will turn on (commonly known as the cut-on pressure). When the pressure in the system rises to the preset high setting the pump will turn off (commonly known as the cut-off pressure). They can be wired to work with 115 or 230 volts.
Can a pressure switch be wired?
With basic electrical knowledge, a pressure switch can be installed and wired with a few tools and materials.

What happens when water pressure increases in a water tank?
As the tank is filled, the water pressure increases within it. When the tank reaches its peak pressure, typically at 60 pounds per square inch, the switch cuts the electrical power to the water pump. As water is used, the pressure in the tank decreases.

Final Thoughts
We hope this step-by-step tutorial on how to wire a 220 well pressure switch helps you accomplish an easy task like replacing or installing a pressure switch on your pump.
How Do I Replace My Water Pressure Switch?
A pressure switch is responsible for turning the well pump on and off as the water pressure inside the pressure tank changes. Just like any other mechanical component, it is bound to wear out, and will therefore need to be replaced from time to time.
What is the lower pressure setting on a water pump called?
The lower pressure setting when the pressure switch activates the pump is called the cut-in pressure. After sufficient water has filled the tank, the pressure switch turns the pump off at the cut-off pressure.
How to tell if a pressure switch is bad?
The signs of a faulty pressure switch are exhibited by a continuously cycling pump, low water pressure or a pump that does not start, meaning no water in the house. A bad pressure switch will need to be replaced.
How to remove wires from a phone?
You will need a screwdriver to loosen the screws and pull out the wires. Before doing anything however, I would recommend that you grab your phone or a digital camera and a take a picture of the connections.
How much pressure should I use to bleed off a tank?
You can either bleed off pressure from the tank or add more using an air compressor or bicycle pump. 2-5 psi lower than the pressure switch’s cut-in pressure will be ideal.
How to check tire pressure when tank is empty?
You should always check the pressure when the tank is empty. Now that your tank is already drained, remove the cap on the air inlet valve at the top of the tank and connect a tire gauge. Check the pressure reading.
How to clean rusty wires?
If the wires are a little rusty, clean them up with an emery cloth. This helps in creating a good contact.
