Quick Answer
Regular maintenance for a deep well hand pump includes inspecting and lubricating moving parts, checking for corrosion, and testing the pump's performance to ensure proper function and longevity.
Inspection and Cleaning
Inspect the hand pump’s moving parts, such as the piston, cylinder, and valves, for signs of wear or corrosion. Clean any debris or mineral buildup from the piston and cylinder using a soft brush or cloth. Apply a thin layer of pump oil to moving parts to maintain lubrication and prevent corrosion.
Piston and Valve Maintenance
Check the piston seal for signs of wear or damage, replacing it if necessary. Adjust or replace the valves if they are not functioning properly. Use a valve adjustment tool to ensure proper valve alignment and function. Typically, valve adjustment should occur every 6-12 months.
Testing and Performance
Test the pump’s performance at regular intervals to ensure proper function and longevity. Measure the pump’s pressure and flow rate to identify any issues. If the pump is not meeting expected performance levels, inspect and adjust the valves, replace the piston seal, or replace the pump as necessary. A good rule of thumb is to test the pump every 3-6 months.
