Read and understand safety and operating instructions in this manual before doing any work on pump!
Only qualified personnel should electrically test pump motor!
Problem
Possible Cause
Corrective Action
The pump will not prime.
The suction piping leaks or
there is no prime.
The pump must be primed. Make sure that the
pump volute and trap are full of water. See
Priming Pump.
Make sure there are no leaks in suction piping.
Make sure suction pipe inlet is well below the
water level to prevent pump from sucking air.
If suction trap gasket is defective, replace it.
The water level is below the
suction pipe inlet.
Make sure pump is not trying to lift water more
than 10 ft. (3 m).
Make sure suction pipe is at least 1-1/2 in. (38
mm) in diameter.
The pump operates, but
it pumps little or no
water.
There is a clogged pipe, trap,
impeller, or there is a worn
impeller.
Make sure suction trap is not clogged; if it is,
clean trap and strainer.
Make sure impeller is not clogged (follow
instructions in Removing Old Seal; check impeller
for clogging; follow
instructions in Installing New Seal for
reassembly).
Impeller and diffuser may be worn. If so, order
replacement parts by calling customer service.
Problem
Possible Cause
Corrective Action
The pump may be
running too slow.
There is an error in the wiring or
the voltage is not set correctly.
Check voltage at motor terminals and at meter
while pump is running. If low, see wiring
instructions or consult power company. Check
for loose connections.
The pump suddenly
stops working.
There is a blown fuse or tripped
breaker.
Replace the fuse or reset the circuit breaker.
The pump may be too hot.
Check line voltage; if less than 90% or more
than 110% of rated voltage consult a licensed
electrician.
Increase ventilation.
Reduce ambient temperature.
Tighten any loose connections.
The pump is
experiencing mechanical
troubles and noise.
The pipe assembly is incorrect.
If suction and discharge piping are not
adequately supported, pump assembly will be
strained. See Installation.
The pump is not mounted
correctly.
Do not mount pump on a wooden platform!
Securely mount on concrete platform for quietest
performance.
