Introduction

Water extraction from deep wells can be challenging, especially in off-grid situations. This guide covers two DIY projects to help you build a manual PVC well pump and a high-volume hand pump using common materials. These pumps can be used for emergency water extraction or as a cost-effective alternative to commercial options.

Understanding Well Depth vs. Water Level

Before starting, measure the static water level in your well, not the total depth. This ensures your pump length matches the water level, not the well’s total depth. For instance, if your well is 100 feet deep but the water level is at 60 feet, your pump needs to be 60 feet long.

Building a Manual PVC Well Pump

Materials

  • PVC pipes
  • Foot valve
  • Couplers
  • Safety rope
  • Chlorine solution

Assembly

Cut and glue PVC sections together, ensuring smooth inner edges for the pumping rod. Allow ample curing time. Attach a foot valve to the bottom of the main pipe and a spout at the top. Use a safety rope to lower the assembly into the well carefully. Replace the well cap with one that has an additional port for the pump.

Operation

Push the rod down slowly and pull up quickly to maximize water flow. The pump can deliver 2-3 gallons per minute with minimal effort (15-30 lbs of force).

Safety and Sanitation

Turn off power, relieve water pressure, and use safety ropes during installation. Dilute chlorine to sanitize pipes. Test water for bacteria post-installation.

Building a High-Volume Hand Pump

Materials

  • PVC pipes
  • 4″ plastic drain covers (Oatey No. 43569)
  • PVC pipe cutter
  • Grinder/lathe
  • Measuring tape

Assembly

Cut and modify the plastic drain covers to fit into standard high-pressure PVC pipes. Create a piston mechanism using the modified drain covers as valves. Assemble the pump using standard PVC pipes and the modified valves. Test the pump to ensure it delivers 50-60 gallons per minute.

Operation

The high-volume hand pump operates similarly to the manual pump but delivers a higher flow rate. Use it for high-demand water extraction scenarios.

Key Takeaways

Both pumps offer cost-effective solutions for water extraction. The manual pump is ideal for deep wells up to 60 feet, while the high-volume hand pump is perfect for high-demand scenarios. Ensure proper sanitation and safety measures during installation and operation.
