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.
