Chapter 7: Troubleshooting & Repair
8. Fluid Check Valves
:
• Open the pump. Hold the pump vertically and pour water into the discharge check
valve. If water flows through, clean the valve.
• The valve assembly may be soaked in a solvent. Be careful to not damage the teflon
ball with the tools used for cleaning.
• Inspect the ball for wear. If it is too small to seal on the seat, or if it is obviously out
of round, replace the check valve.
• If the pump is a Bottom-Loading design, inspect the seat of the bottom check valve
for debris and wear. Clean or replace if necessary.
• If the pump is a Top-Loading design, remove the fluid inlet check valve, turn it upside
down, and pour water into it. If water flows through, clean it.
9.
Air Inlet Valve Timing
:
• Remove the pump casing. Connect the air supply. Push the control rod end of the
lever up to the head. Lower the rod slowly and stop at the point where the sound
of air drops dramatically.
• The levers should be nearly ±10 degrees parallel to the lower surface of the head
at this point.
• Check if the lever is jamming due to an improper adjustment.
