How to install A Well Pump: Step-By-Step Guide
Well pumps come in two main types: submersible well pumps and jet pumps. These different types of well pumps have different installation processes:
Submersible Well Pump Installation
Learn the step-by-step process on how to install a submersible well pump
- Preparation and Safety
Measure how deep your well is and determine the suitable pump cable length. Make sure the well casing diameter suits the pump size.
The first step is to turn off the breakers and disconnect the electrical connection.
If you have plenty of sunlight where you live, you might want to consider buying a solar submersible well pump. They use less energy.
- Lower the Pump
Carefully lower the pump and discharge pipe assembly down the well. Use a strong rope or wire to hold it in place and stop it from getting caught on anything. You might need special parts called borewell submersible pump fittings, depending on how your well is set up.
- Electrical Connections
Connect the pump's power cable to the electrical box located at the top of the well. Run the cable to your pressure tank and electrical controls, which will regulate pump operation.
Ensure the electrical connection is safe by following local electrical codes
- Test and Activate the Pump
Fill the pressure tank with air according to the manufacturer’s specifications. Switch on the power and monitor the pump for any leakage and check if its functioning correctly.
Shallow Well Pump Installation
Here are the basics of how to install a shallow pump.
- Fix the Shallow Well Pump
Install the shallow well pump according to the manufacturer's guide. Make sure all the pipe joints in the suction pipe are airtight and watertight.
- Provide Proper Alignment and Support
Adjust the pump mounting height to connect to the plumbing system. Secure the pump with clamps or sturdy brackets. This will prevent them from being pulled down by their weight or fittings.
- Install the Valve
Install a one way check valve in the feed line that connects to the pump. This will keep the water in the shallow well pump and the plumbing system instead of going back down to the well.
- Test the Shallow Well Pump Samples
Run the shallow well pump and check various water samples before you use them. Check if the water is clean and it should be free of silt, sand and other materials such as minerals and chemicals.
- Add a Pressure Tank
Consider adding a well pressure tank when installing or replacing a shallow well pump. This will help keep the water pressure constant and reduce wear and tear on the pump motor.
Deep Well Pump Installation
Follow these steps, which will help you on how to install a deep well pump.
- Measure the Well Depth
Choose an appropriate pump size depending on how deep your well is. If you don't know how deep your well is, attach a weight to a string at least 500 feet long and drop it into the well until it touches bottom. Mark the string where it is level with the ground.
- Choose a Larger Pump
Consider a larger pump than the depth of your well, especially if you are pumping water uphill or over a long distance. Ask for professional help if you are not sure which well pump is suitable.
- Choose the Right Pump Control Box
Select a pump control box with the same horsepower rating as your deep well pump. This is because the control box is responsible for regulating the power supply to the pump.
Underpowering a pump can lead to overheating and potential safety hazards.
- Install a One-way Check Valve
A one-way check valve is an essential component of any well pump system. It prevents water from flowing back into the well when the pump is turned off. It also makes sure the well delivers water immediately when the pump is restarted.
- Install a Pressure Tank
A pressure tank is a valuable addition to any well pump system that will keep the water pressure constant. With the help of a pressure tank you can also reduce the wear and tear on the pump motor.
The final step is to follow the manufacturer’s instructions that come with your well pump. While it is possible to do it yourself, it is highly recommended to consult with a licensed professional if you are unsure about any part of the process.
Installing a pump in a well requires careful planning and attention to detail to make sure ideal performance and longevity. By following the manufacturer's instructions and seeking professional assistance when necessary, you can achieve a successful installation.
