Valve Replacement: All inlet and discharge valves can be serviced without disrupting the inlet or discharge
plumbing. The inlet and discharge valves are identical in all 66 TSF series models.
To service any valve:
1) Remove valve cap and examine o-ring. Replace o-ring if there is any
evidence of cuts, abrasions, distortion or wear.
2) Remove valve assembly (retainer, spring, valve, valve seat) from
valve cavity.
3) Remove valve seat o-ring from valve cavity.
4) Inspect manifold for wear or damage.
5) Install new o-ring in valve cavity.
6) Insert valve assembly into valve cavity.
7) Replace valve cap and torque to specification.
NOTE: Only one valve kit is necessary to repair all the valves
in the pump. The kit includes new o-rings, valve seat, poppet, spring and
retainer. All are pre-assembled.
