4. Use snap ring pliers to remove snap ring and E-clip. Remove check ball and examine
foot valve for debris and/or damage. Replace as necessary. Replace Teflon O-ring and
re-assembly foot valve with ball, snap ring and E-clip.
A NOTE ON FOOT VALVES:
All foot valves have been converted to a higher flow
capacity. This is a design element to reduce out-gassing and suction pressure within the
pump. While the foot valves are readily interchangeable with the older style the internal
components are not, so take care when ordering replacement parts.
5. With a strap wrench close to outlet housing, unscrew the air cylinder taking care NOT
to bend the piston rod in the process. Examine air cylinder for damage to the interior
cylinder wall by looking through the cylinder at an acute angle to a light source.
