You’re planning to build a new well. The relay switch is a part of this process. As of that, you would like to know the necessary information about this switch.
What is a well pump relay switch?
The relay switch of the well pump is used when your pump is turned on or off. It’s used in submersible pumps with higher horsepower. A pump relay switch mostly controls the operation of the electric motor of your pump. This switch is quite useful for the well or any kind of pump.
This information is not enough for you. So, spare some time and stay back to get the information in depth.
Sounds good? Let’s get started right away!
How Does A Well Pump Relay Switch Work?
In well applications, a well pump relay switch is frequently found. This relay switch is used in submersible, reciprocating, and jet pump systems. It’s utilized as a way to transport water from the well to your house.
With greater horsepower submersible pumps, a pump relay switch is utilized. This switch tells the pump when to power on and off.
Relay switches are known to monitor your water system. They electrically start or stop your well pump.
It also helps to pressurize the home’s plumbing system. Additionally, this can also prevent water pressure regulator issues.
On the other hand, electrical wire supplies the relay switch with the electricity. Because this is needed to operate. Besides, wiring connects the submersible water pump on the other side.
This is the functionality of a well or water pump relay switch.
How To Install Well Pump Relay Switch Easily?
After going through the info, you can move to install the switch. Make sure the area where you’re going to work is dry.
You also have to get these tools mentioned below-
- Hand gloves
- Two-pole pump relay switch
- Wire stripper
These are the equipment you need. By the way, for this task, you have to use rubber insulated or nitrile gloves. This type of gloves is used while attaching duct board plenums to your air handler too.
Not sure where to get the gloves from?
Don’t worry! Here are some suggestions-
After getting the gloves, make sure you wear them properly.
Anyway, install this switch following the simple methods provided below-
Step 1: Connecting The Wires Accordingly
Understand that the two-pole relay switch will have three pairs of wires attached to it. The first wires should be attached to the control coil of the relay. Then a magnetic field is produced by the coil, which controls the electrical contacts of the relay.
The second set of cables will come from the electrical source on the main panel. A circuit breaker (Two-pole) or two fuses are needed for a 220 VAC pump.
Finally, the last pair comes. This pair of wires that are attached to your relay will go to your pump motor.
Step 2: Placing The Relay Switch
Place the two-pole pump relay switch somewhere dry. Do it at least 5 feet off your ground.
Utilize the mounting screws provided by the vendor afterward. With the screwdriver, fasten the switch mechanism to a sturdy wall.
Step 3: Turning Off The Power
Turn off the electricity to the pump motor circuit. Turn the circuit breaker off as well. You can also turn off any fuses that supply electricity to the pump motor.
Because power being on while installing the relay switch is extremely risky. This might eventually force you to replace the well pump later on.
Because you’ll see signs that your well pump is going bad. This is why make sure you turn off the pump’s electricity.
Step 4: Separating The Bare Copper Wire
It’s time to employ the wire strippers. The wire insulation should next be removed to a depth of about 3/4 inch. This will assist in separating the bare copper wire from the other wires.
Step 5: Connecting The Wires to Terminals
The wires from the pressure switch need to be linked to each screw terminal now. Simply put, one wire should be connected to each terminal. You’ll notice that one of these wires is a voltage-carrying “hot” wire.
On the other hand, the electrical system neutral will be connected to the other cable. The voltage should be 120 VAC between these two wires.
An important point should be added. While connecting these, you may have some unknown issues. In that case, your well pump turns slow to build pressure.
Step 6: Attaching Cables to Pump Motor
Identify the labels that follow on the relay switch now. Label one pair of screw terminals as “Line”.
The opposite pair of terminals should be identified as “Load”. The wires from the main power fuse or circuit breaker must then be connected.
Attach them to the “Line” marked screw terminals. Remember to connect one wire to each terminal once more.
Attach the cables going to your pump motor now. Connect these to each of the “Load” labeled screw terminals. Each terminal should have only one wire.
Step 7: Turning On The Power Again
Last but not least, re-energize your main power. To do so, turn on the circuit breaker. Or you can also replace your power fuses.
That’s all! You’re now done installing the relay switch.
Question: How to troubleshoot a well pump?
Answer: Ensure the well switch near your pressure tank hasn’t been turned off first. Then look to see if the well’s double-pole circuit breaker has tripped. If it has, it should be reset. A breaker that is constantly tripping indicates a problem with the well pump. This requires the assistance of a professional.
Question: How to test a well pump’s pressure switch?
Answer: Start by cleaning and inspecting the switch relay contacts. Look for burning or pitting on the surface of the four contacts afterward. If the pressure switch shows symptoms of wear, it may need to be replaced. If not, sand it down with fine-grit sandpaper. This will aid in the removal of any dirt or debris, revealing the gleaming metal.
Question: Why is my switch not turning on?
Answer: The switch not turning on is quite a common issue. This could indicate that your tank pressure is higher than the switch’s cut-in pressure. To fix this, run water from another location in the structure. This would aid in lowering pressure below the cut-in point. You can also lightly tap the switch, the pressure gauge, and the tank.
Now, you know what a well pump relay switch is! We tried to bring out the information about it and how it works. We hope you like our information regarding the well pump relay switch.
All the best with your home improvement!
