I am going to be changing out my 2 HP Hayward Super Pump and am thinking about going with a Variable Speed pump. I see most companies carry Variable Speed and Variable Flow both with Safety Vaccuum Release options. Would a Variable Flo pump with Vaccum release be overkill for my residential pool in MD? Does any law mandate I have a variable speed or Vaccum Release for that matter?
Any recommendations on which manufacturer has best pump on market? Intelliflo by Pentair was brought to my attention...Does it matter I have Hayward Valve and Hayward Filter?
