Hayward TriStar Pump System SP3215, 8 yrs old. HW Pro-Grid DE Filter, 60SF

  1. Need to replace Hayward SP3215Z1BE 1 1/2HP pump and want to upgrade to 2HP motor, should SPX3220Z1BER be the correct upgrade pump? Or, pump B2748 on P/N-B748 or pump P/N-B855? What are the major differences in these 3 pumps?
  2. Current impeller is SPX3215C 1.50JP/2.0THP. Does current impeller need to be upgrade to SPX322C?? Why???
  3. What other parts are required to be replaced or upgrade to complete motor replacement?
