Introduction

A hand pump provides a reliable water source during power outages, emergencies, or off-grid living. This guide combines techniques from multiple sources to ensure functionality for depths up to 75 feet, though performance may vary based on design and materials.

Materials Required

  • 1-1/2″ PVC pipe as a guide sleeve with a cap on the bottom
  • 1/2″ holes drilled above the cap for water intake
  • 3/4″ NPT to hose adapter
  • 5/8″ garden hose (ID)
  • 1/2″ carriage bolts, washers, and nuts
  • 3/4″ PVC schedule 40 pipe and adapters
  • 1/2″ nylon cord
  • 1-1/2″ PVC collar
  • 3/4″ foot valve (ensure compatibility with hand-pumping pressures)
  • 1/8″ weep hole in the pump shaft (for cold climates, drill below frost line)
  • PVC solvent and glue
  • Drill and bits
  • Wrenches, pipe wrenches, and crescent wrenches
  • Allen wrench
  • Well cap
  • Optional: copper/brass components for fuel compatibility (heavier and more prone to freezing)

Assembly Steps

  1. Prepare the 1-1/2″ PVC guide sleeve with a cap on the bottom and 1/2″ holes drilled above the cap for water intake.
  2. Secure the sleeve to the well casing using 1/2″ carriage bolts, sealing bolt holes with rubber washers or caulking.
  3. Install the foot valve at the bottom of the pump shaft, ensuring it opens during the downstroke and closes during the upstroke.
  4. Drill a 1/8″ weep hole in the pump shaft above the foot valve but below the frost line to prevent freezing in cold climates.
  5. Attach a hollow shaft to the guide sleeve, extending at least 3-5 feet below the water table for optimal function.
  6. Connect the pump to a garden hose or pipe for water discharge.
  7. For storage, use a prussik knot or hook system to hang the pump inside the well casing.

Key Considerations

  • Ensure all PVC components have matching thread counts.
  • Disinfect hands and pump parts before installation.
  • Test well water for contaminants if using untested sources.
  • Use copper/brass components for fuel compatibility, though they are heavier and more prone to freezing.
  • Pump efficiency decreases beyond 50 feet; two people may be needed for deeper wells (some sources suggest effectiveness up to 20 feet).
  • Trim foot valve closure springs if necessary to ensure compatibility with hand-pumping pressures.

Operation and Maintenance

  • The foot valve opens during the downstroke, allowing water to flow upward. Repeated pumping creates a hydraulic ram effect, discharging water through the hose on the downstroke.
  • Keep the well cap sealed when not in use to prevent contamination.
  • Clean and disinfect stagnant wells with a power pump if necessary.
  • Use water treatments (boiling, filters) for untested water to prevent disease.
  • Regularly inspect and replace worn parts, especially seals and valves.
  • Maintain sanitation around the well area to prevent disease transmission.

Safety and Depth Limits

  • Test well water for contaminants before use.
  • Avoid contact with sick individuals.
  • Local health departments can assist with well testing and sanitation.
