PUMP PRIMING AND STARTUP
4. Check to be sure water in the cavity of pump
stays constant. If water level goes down, it
could indicate a leak in the foot valve, check
valve or suction pipe.

6. Turn on breaker to start pump.
IMPORTANT:
If the pump hums instead
of pumping or turns off repeatedly, shut pump
off immediately. Check voltage. Make sure
your incoming voltage matches the pump
wiring voltage. See PUMP ELECTRICAL
CONNECTIONS.
IMPORTANT:
If pump fails to prime within
five minutes:
Turn power off at the breaker box and check
all pipe connections for leaks. All connections
must be water and air tight in order for pump to
operate.
7. Check suction pipe for any sagging. Support
suction pipe in a straight line to the pump.
NOTE
: Look for leaks or a milky color in the
discharged water, which indicates an air leak.
Re-prime if necessary, following steps 1 through
6 above. Reset breaker at the breaker box. All
connections must be water and air tight in order
for pump to operate.
