Need some advise on a new pump please. Pool is only 6 years old but motor needs replaced and pump needs parts also so i figured now is the perfect time for an upgrade. Currently have a whisperflow wf-28 2HP single stage uprated pump. i do have a spa. I was considering the Jandy Pump as my control panel is the JandyRS-8 with the aqualink spa control. I have no idea why my PB mixed the control panel and the pumps. I do have 2" piping. If i buy the Pentair intelliflow can i just slide the motor and assembly in to the WF-28 pump housing ? That sure would make things super easy without having to do any plumbing. Any thoughts please.
