Can You Put a Hand Pump on a Deep Well? Exploring the Possibilities

by

Can you put a hand pump on a deep well? The answer is yes, but the feasibility and installation process depend on various factors, including the well depth, water table, and the type of hand pump used. In this comprehensive guide, we’ll delve into the technical details and explore the possibilities of installing a hand pump on a deep well.

Understanding Hand Pump Capabilities

Hand pumps are a versatile and reliable water-lifting solution, but their effectiveness is largely determined by the depth of the well. Generally, standard hand pumps can lift water from depths up to 25 feet. However, for deeper wells, specialized deep well hand pumps are required.

Shallow Well Hand Pumps

Shallow well hand pumps, also known as suction pumps, rely on the creation of a vacuum within the pump cylinder to draw water up from the well. These pumps are suitable for wells with water tables less than 25 feet deep. The pumping mechanism is located above the water level, making them a popular choice for shallow applications.

Deep Well Hand Pumps

For wells with water tables deeper than 25 feet, deep well hand pumps are the solution. These pumps have the pumping mechanism lowered into the well, allowing them to lift water from greater depths. The pump cylinder is submerged in the water, eliminating the need for suction and enabling the pump to function effectively in deeper wells.

Types of Deep Well Hand Pumps

When it comes to deep well hand pumps, there are several types to consider, each with its own unique features and capabilities.

Force Pumps

Force pumps are a type of deep well hand pump that are particularly useful when the water table is more than 22 feet below the surface. These pumps can generate higher pressure, allowing the water to be discharged with greater force, making them suitable for applications that require water to be pumped through a hose or other delivery system.

Piston Pumps

Piston pumps are another common type of deep well hand pump. These pumps use a reciprocating piston mechanism to draw water up from the well. Piston pumps are known for their durability and can be used in wells up to 200 feet deep, depending on the specific model.

Diaphragm Pumps

Diaphragm pumps are a variation of deep well hand pumps that use a flexible diaphragm to create suction and push water up from the well. These pumps are often preferred for their low maintenance requirements and ability to handle water with suspended solids or debris.

Installation Considerations

When installing a hand pump on a deep well, there are several important factors to consider:

Well Casing Size

The most common well casing size for hand pump installation is 6 inches in diameter. However, hand pumps can also be installed in 4-inch well casings, though the options may be more limited.

Pump Placement

The hand pump unit is typically installed directly on top of the well, replacing the sanitary cap. The pump’s pumping mechanism is then lowered into the well, with a separate pipe running alongside the submersible pump’s pipe.

Compatibility with Submersible Pumps

In many cases, hand pumps are installed in the same well as a submersible pump. This allows for both manual and electric water-lifting capabilities, providing a backup water source in the event of power outages or other emergencies.

Installation Costs

The cost of installing a hand pump on a deep well can vary significantly, depending on factors such as the well depth, the type of hand pump selected, and the location of the installation. It is recommended to consult with a professional water well drilling service to obtain an accurate estimate for your specific project.

Maintenance and Troubleshooting

Proper maintenance and regular inspections are crucial for ensuring the long-term performance and reliability of a hand pump installed on a deep well. This includes:

  • Regularly lubricating moving parts
  • Checking for wear and tear on the pump components
  • Ensuring the pump is securely mounted and the well casing is in good condition
  • Addressing any issues with water flow or pump performance promptly

In the event of a malfunction or reduced water output, it’s important to troubleshoot the issue and identify the root cause. This may involve inspecting the pump mechanism, checking for blockages in the pipes, or verifying the water table depth.

Conclusion

Installing a hand pump on a deep well is a viable option, but it requires careful consideration of the well depth, water table, and the specific type of hand pump required. By understanding the technical details and following best practices, you can successfully integrate a hand pump into your deep well system, ensuring a reliable and versatile water-lifting solution.
