So I have a I just bought a house and the pool is older around 13000 gallons with 600 gallon spa. The problem is the pool only has one skimmer with 1.5" return line. Main drain is plumed to the skimmer. Spa also has main drain connected to spa skimmer and again 1.5" return to pump. Pool runs on aqualink RS and single speed pump that is dieing. I will replace with variable speed. The question. Is which one. Intellifow will be to powerful so I am thinking of going with pentair Superflow or Jandy Epump. Now the Jandy may not be as good but will fully connect with the aqualink or the Superflo that only connects useing up aux relays.with is really annoyeing. So any suggestions? Thank you
