A. Be sure suction pipe is in the water.
B. Be sure suction pipe does not leak.
C. Be sure that pump is not trying to lift water too high
(see "Piping in the Well", Page 3).
D. As long as foot valve and check valve function
correctly and suction pipe does not develop leaks,
pump should not need repriming in normal service.

shaft seal in the pump is water lubricated and self-
adjusting.
