6: In addition to limiting the current draw from the mains during start-up of the pump, how does the soft-start functionality benefit operation?
Soft start reduces over-pressure in your piping.

6: In addition to limiting the current draw from the mains during start-up of the pump, how does the soft-start functionality benefit operation?
It reduces the occurrence of water hammer in the pipes and minimises wear during start-up.
6: In addition to limiting the current draw from the mains during start-up of the pump, how does the soft-start functionality benefit operation?
Soft start prevents the motor from getting warm.
