Understanding Your Jet Well Pump System

Before we get started with the installation, it’s crucial to understand the basics of how a jet well pump works. These pumps are designed to draw water from a well using a suction process. They are commonly used for shallow wells (up to 25 feet deep) and can be configured for deeper wells with a few adjustments. In this guide, we’ll focus on the more common shallow well setup, where the ejector is located within the pump itself.

Shallow vs. Deep Well Systems: Key Differences

It’s essential to correctly identify whether you have a shallow or deep well system. This guide specifically addresses shallow well systems, where the water source is less than 25 feet deep. If your well is deeper than this, you’ll need a different type of pump and installation approach, so please refer to our deep well pump installation guide or consult a professional. Understanding this difference is the first step to a successful installation.

Voltage Configuration: 115V or 230V?

Our convertible jet pump comes pre-wired for 230 volts but can easily be switched to 115 volts, making it adaptable to most household electrical systems. If your home uses 115 volts, you’ll need to change the setting before installation. Here’s how to make the switch:

1. Access the Switch: Carefully remove the top cover of the pump to expose the internal components.
2. Locate the Selector: Find the voltage selector switch, which is initially set to 230 volts.
3. Adjust the Switch: Slide the switch to the 115-volt position.
4. Replace the Cover: Securely replace the top cover of the pump.

Your pump is now correctly configured for a 115-volt electrical system.

Step-by-Step Installation Guide: Replacing Your Jet Well Pump

The installation process can be broken down into three main sections: removing the old pump, installing the new pump, and testing the system. Let’s get started!

Step 1: Prioritizing Safety First

Before you begin any work on your well pump, it’s critical to prioritize safety. Improper installation can lead to damage or injury. Follow these safety measures:

• Read the Manual: Thoroughly review all safety information and instructions in your new pump’s installation manual.
• Power Off: Turn off the power to the pump at the main electrical panel or disconnect box. Double-check using a non-contact voltage tester to confirm the power is completely off.
• Water Off: Shut off the main water supply to prevent any water from flowing during the removal and installation process.

Step 2: Removing the Old Well Pump

With all safety precautions in place, it’s time to remove the old pump.

1. Relieve Pressure: Use an adjustable wrench to carefully loosen the pressure relief valve on the existing system. This will release any built-up pressure in the system.
2. Drain the Pump: Locate the drain plug at the bottom of the old pump. Loosen and remove the plug, allowing any remaining water to drain completely. Use a container to collect the water and prevent a mess. Once drained, replace the plug to prevent spillage.
3. Disconnect Piping: Use pipe wrenches to disconnect the incoming suction line from the shallow well and the outgoing line to the pressure tank. Be prepared for some resistance and use steady, controlled force.
4. Disconnect Pressure Switch Wiring: Carefully unscrew the nut securing the pressure switch cover. Disconnect all electrical wires, including the ground wire, ensuring to note their positions for reinstallation.
5. Remove the Old Pump: Now that everything is disconnected, carefully lift the old pump out of its place. You may need assistance if it is heavy.

Step 3: Preparing for the New Jet Well Pump Installation

Before installing the new pump, it’s crucial to inspect and prepare your well system components for optimal performance.

1. Inspect the Foot Valve: The foot valve, a crucial check valve at the bottom of the suction pipe, is essential for maintaining prime in a shallow well system. Check it for any damage, wear, or debris. If it’s faulty, replace it with a new one. The foot valve is typically located at the bottom of the suction pipe, either inside or just outside the well.
2. Check the Piping: Examine the suction pipe for any signs of rust, calcium buildup, or other damage. Replace the pipe if necessary to ensure a secure and efficient connection.
3. Prime the Suction Pipe: Remove the priming plug from the suction side of the pump and fill the suction pipe completely with water. This is critical to help the pump create suction and draw water effectively.

Step 4: Installing the New Jet Well Pump

Now let’s get the new pump in place.

1. Connect the Outgoing Line: Begin by connecting the outgoing line from the pump to the pressure tank. Use Teflon tape on all threaded connections to prevent leaks.
2. Connect the Incoming Line: Next, connect the pump to the incoming suction line from the shallow well. Again, use Teflon tape on all threaded connections.
3. Tighten Connections: Ensure all pipe connections are snug and secure using your pipe wrenches. Do not overtighten.
4. Prepare the Priming Port: Attach your pressure outlet line valve and make sure it is in the closed position.

Step 5: Priming the New Jet Well Pump

Priming the pump is essential to remove air and allow it to draw water correctly.

1. Fill the Pump Housing: Remove the priming plug on the top of the pump housing. Fill the pump housing completely with water until it’s full, and you see air bubbles escaping.
2. Replace the Priming Plug: Once the pump housing is full, replace the priming plug, ensuring it is tightly secured.

Step 6: Connecting the Electrical Wiring

Now, let’s connect the electrical wiring to the pressure switch. Note: If you’re not comfortable with electrical work, consult a qualified electrician for assistance.

1. Access the Wiring: Carefully remove the cap of the pressure switch to access the wiring connections inside.
2. Install the Ground Wire: Connect the ground wire to the designated ground pin inside the pressure switch.
3. Connect Power Wires: Attach the two incoming power wires to the appropriate terminals on the pressure switch, as per your manual.
4. Replace the Grommet: Reinstall the grommet to create a tight seal and protect the wiring from moisture and debris.
5. Secure the Cap: Reattach the cap to the pressure switch, making sure it’s securely in place to protect the electrical connections.

Step 7: Testing the Newly Installed Jet Well Pump

With everything connected, it’s time to test the pump and ensure everything is working correctly.

1. Restore Power: Turn the power back on at the breaker or disconnect box.
2. Open Valves: Make sure all the water valves that were previously shut off are now open.
3. Start the Pump: Turn on the pump and listen for the motor starting.
4. Evacuate Air: Open a faucet slightly to allow any remaining air in the system to escape. Monitor the water flow to ensure it’s consistent.

Troubleshooting Common Jet Well Pump Issues

Here are a few common problems you might encounter after installing your new jet well pump and some troubleshooting tips:

• Pump Fails to Prime: Ensure the foot valve at the bottom of the suction pipe is working correctly. Double-check that the suction pipe is completely full of water and all connections are tight and leak-free.
• Pump Runs Continuously: Check for leaks in the system, including pipe connections and the pressure tank. A faulty pressure switch could also be the cause.
• Low Water Pressure: Make sure the pump is primed correctly and that there are no clogs or blockages in the system. Check the pressure tank and pressure switch settings.

Key Takeaways for Successful Jet Well Pump Installation

Installing a new jet well pump is a manageable project if you follow these steps carefully. Remember to prioritize safety, prepare thoroughly, and double-check all connections for leaks. By following this guide, you can ensure a smooth and efficient installation, bringing reliable water flow back to your home.
