I am looking to replace my filter and pump. I currently have a American products pump 2 hp service factor is 1.1 or 1.15 and a titian DE vertical grid filter 36 sq ft . my pool is about 14,000 gal with a spa attached. It has 4 jets for the spa and 1 return in the spa and 2 return in the pool. I have a sand shark with a vac mate in the skimmer. the plumbing in the pad area is all 2 inch. I have a home warranty and they want to replace it with a waterworks pump and filter same size. I don't want this so I am taking the cash option and going to by better equipment. I am trying to stay close to dollar amount with what they are giving me. I am looking at the Pentair DE quad 60 sq ft filter but not sure which pump to go with . pool shop said the Pentair 2hp superflo is a option but I would like to go with the wisperflo but not sure I really need a 2 hp . but want good pressure for my spa. right know when I clean my filer (I have dogs that swim) about evry 7 weeks and I have so much suction that I cant regulate the flo on the sand shark I have the setting on the vac mate to the skimmer side and the sand shark climbs the walls and when it hit the water line and turns it sucks air and gets stuck. so I have a plug in the skimmer to the main drain and I have to unscrew it so it sucks some water from it to reduce the pressure . you have any suggestions on hp of a new pump
