NOTE: Suction leaks are the largest
cause of poor pump performance
and are difficult to detect. Ensure all
connections are completely sealed
using thread tape only. Do not use
sealing compounds or pipe dope.
WHERE TO USE CHECK VALVES
AND FOOT VALVES
Installations with a suction lift require a good quality
foot valve to avoid loss of prime.
Installations with flooded suction require a gate
valve so water supply can be turned off for pump
removal and servicing.
Installations with overhead tanks and pipe work
require a one-way check valve to avoid water
draining back past the pump while not in operation
and causing possible pump damage.
PRIMING AND OPERATION
1. Ensure outlet nearest to pump is open.
2. Fill pump body and suction line through priming plug
hole located above suction inlet and replace plug.
3. Switch on.
