This is my first post to a forum. I'm planning on upgrading/replacing all my equipment as I've had some electrical issues and lost use of the pump for my spa years ago. I was told the electrical lines were likely wet and wires have gone bad. I'm going to have at least a minimum 50 AMP subpanel installed (i have a gazebo that I want wired as well as the pool equipment). Here is my plan, Replace 49 sq ft sand with cartridge CCP520, replace 1.5 MaxEGlass with Intelliflo VS, add CCP320 cartridge to the Caretaker/Waterfeature (i'm tired of cleaning the screens and have worn out the threads on the Caretaker valves). My question is figuring out the correct, most energy efficient pump for the caretaker and waterfall. I need the same advise for the spa pump. I was thinking Whisperflo WFE-6 for both.
