DIY: How to Replace the Shaft Seal on Your Clearwater Well Pump

Identifying When to Replace the Shaft Seal

Water seeping around the edges of your pump housing or water accumulating near the pump can signal a worn or damaged shaft seal. However, these symptoms can also be caused by other issues like improper installation, insufficient pressure, or a malfunctioning pump. Regular maintenance, including checking the water level in your well and ensuring the pump is functioning properly, is crucial to prevent these problems.

Gathering the Necessary Tools and Materials

Replacing a shaft seal requires the right tools and materials. Here’s what you’ll need:
- A flat wrench or pump tool
- A set of Allen keys or magnetic bar
- Pliers
- Insulation tape
- A new shaft seal kit (specifically designed for your Clearwater well pump)
It’s a good idea to have a spare shaft seal kit on hand in case you need to replace the seal multiple times. Using the correct seal kit is essential to prevent a poor fit and potential leaks.

Prepping the Area and Turning Off Power

Before you can replace the shaft seal, ensure the area is safe and the pump is shut down properly. Turn off the power to the pump and the main electrical supply to prevent electrical hazards and protect yourself from electric shock.
To do this, locate the electrical panel connected to your well pump and switch off the power. If you’re unsure about how to do this safely, consider consulting a professional. Once the power is off, drain the remaining water from the pump and well to prevent moisture from entering the pump housing.

Removing the Old Shaft Seal

Careful disassembly is key to removing the old shaft seal. Start by unscrewing the pump housing from the well casing. If the pump housing is secured with multiple screws, use a flat wrench or pump tool to loosen and remove them one at a time. Be sure to keep the pump housing in place until you’re ready to replace the seal.
Once the pump housing is removed, locate the old shaft seal and prepare to replace it. Carefully remove the old seal using Allen keys or a magnetic bar. Be gentle to avoid damaging the pump shaft, which could lead to further leaks or damage.

Replacing the Shaft Seal

Replacing the shaft seal is a precise process that requires attention to detail. First, select the appropriate shaft seal for your Clearwater well pump. There are several types available, including rubber, metal, and composite seals. Rubber seals are durable, flexible, and resistant to fatigue.
Once you’ve chosen the right seal, clean and lubricate the pump housing surface to ensure the new seal fits properly and reduces friction. Align the new seal with the existing seal on the pump shaft, ensuring no gaps exist. Apply the appropriate amount of pump oil or lube to ensure proper lubrication.
Finally, reassemble the pump housing, securing it with all screws, and realign it with the pump shaft. Ensure all bolts are properly tightened. This completes the shaft seal replacement process.

Reassembling the Pump and Testing Operation

After replacing the shaft seal, reassemble the pump and test its operation. Reconnect the electrical connections, turn on the pump, and let it run for a few minutes to ensure it’s functioning properly.
Pay close attention to the base of the pump for any leaks or water accumulation. If you notice water seeping from the base, it may indicate a problem with the new shaft seal or the pump housing. Also, check the water level in the well to ensure it’s within the recommended range for your pump.
If everything seems to be in order, your pump should run smoothly for years to come. Regular maintenance, including checking the water level in your well and ensuring the pump is functioning properly, is key to preserving your pump’s longevity and preventing costly repairs.

Long-Term Maintenance Considerations

While this guide focuses on replacing the shaft seal, adopt these long-term maintenance practices to ensure your well pump continues to operate efficiently:
- Regular Water Level Checks: Ensure the water level in the well is within the recommended range to prevent overwork and potential damage.
- Inspected Components: Regularly inspect the pump housing for signs of wear or damage, such as cracks or holes.
- Replacement of Worn Parts: Replace any worn-out or damaged components, such as gaskets or bearings, to prevent further issues.
- Professional Consultation: If you notice any problems with your pump, consult a professional for assistance.
