My neighbor has a Pentair 3HP VS pool pump that recently went out. The pump is most likely not worth fixing, so I am trying to help him pick a new pump. I think that a 3HP pump is bigger than he needs, and he can go with a smaller pump. I am thinking of a smaller pump because of the cost. The current equipment pad is maybe 15ft to 20ft from the skimmer. He also has solar that is almost directly above his equipment pad. The solar consists of four 12x4ft panels. The house is one storey. I think the filter is a Hayward Swim Clear 225 or 325. I believe all the pipes are 2". Would a 1.5HP or 2HP pump be able to prime the solar system?
