I purchased my system 2 years ago. Within the first 6 months the pump stopped. Upon returning it to the store they did not have a 1.5 hp replacement so they gave me the 2 hp. After reading a few posts on here, I'm now wondering if it's too big?? The pump is a Pentair Turbo King and the filter is an Artesian. My pipes are 1.5 in. If you need more info please let me know.
