Hi , I have a 16 x 32 Doughboy pool with a deep end that I put entirely in the ground. The pool came with a 1 hp pump and sand filter set up . The problem I'm having is when I try to clean the pool with the automatic pool cleaner it doesn't seem to prime itself , like the pump isn't strong enough. The pump is on the ground ,so it's pumping up at the most 6 feet of head. I want to put the pump and filter in a shed which would be another foot or so above the lowest point of the pool . I'm considering a 1.5 HP 2 speed pump to help my situation. Just wanting feedback or suggestions.
