newbie attempting to replace pool pump

Use schedule 80 male adapters on the intake and discharge side of the pump, If the pump unprimed the schedule 80 will not melt like schedule 40 will.

From experience I can assure you that with a Pentair whisperflow 1 hp pump you will not melt the sch 40 fittings. My wife did this experiment for me. She set the valve to waste (while the pump was off) and never checked the pool again until I came back from a trip, five days later. So I know that sch 40 can hold up to 8-12 hour cycles completely dry for a week.

Thanks for all the info! One more thing, I have a whisperflo 115/230 pump. My previous motor was a hayward super II with a stated 230v. How do I make sure that the whisperflo is set to 230v?

Thanks

Specific connections should be explained in the manual that comes with the pump. Sometimes the info is on the inside of the back cover of the motor.

Schedule 40 fittings connected to pool pumps will warp if the pump overheats. Owned a pool service company for twenty years and made a small fortune repairing warped schedule 40 fitting on pool pumps (including whisperflow) installed by pool builders. Use schedule 80 fittings. The wiring diagram for the pump is on the side of the pump motor. Make sure to reconnect the bondwire to the bonding tab on the back of the new pump motor.
