I have a 2 hp single speed Pentair pump that is on its last leg. 12 years old. I figured I would replace with a variable speed pump but don't know anything about them. I don't have any automation and is just run off a timer to run 10 hrs a day. I installed a circupool RJ-60 last year and was wondering if there was any advantage with going with one of their pumps or something else. Any help would be appreciated. It's for a 22000 gal in ground pool in NJ
