casuing pump not to flow.
(11)
Pumprunning backwards.
(12)
Check valve is partially
closed or installed
backward.
(8)
fixtures are leaking.
(13)
Groundwater is entering
basin.
(17)
Wiring or electrical current
is inappropriate.
(1)
The total dynamic charge
is below the
recommended minimum.
(6)
Impeller is jammed or
bounds near the pump
body.
(10)
Excessive water
temperature (internal
protection only).
(14)
Worn bearings, the motor
shaft bent.
(4)
Obstruction in the cavity
of the impeller or is
impaired.
(10)
Impeller rotation is
incorrect.
(12)
Piping attachments to
build dtructure too loose
or rigid.
(15)

escape. Verify that turn-off level of switch is set so
that the suction is always flooded. Clean vent hole.
(12)
Check rotation. If power supply is three phase,
reverse any two of three power supply leads to
ensure proper impeller rotation.
(13)
Repair fixtures as required to eliminate leakage.
(14)

pumped, which must not exceed 160 ° F ( 71 ° C).
(15)
Replace portion of discharge pipe with flexible
connector or tighten existing piping..
(16)
Turn to automatic position.
(17)
Check for leaks around basin inlet and outlets.
E) The pump turns on and off
