We “inherited” our pool with the house we bought four years ago. We know that it is technically an above ground pool, though dug and built partially into the ground. It is 15x30 with a shallow end that is approx 4 ft and a slope down to 6 ft. The pump broke and last year we were noticing some sand in the pool. I was thinking that something inside may be cracked. I realize this can be fixed, but being that the pump also broke, and we know nothing about how old any of the equipment is, we figured we would start from scratch and buy both new. I’m stuck on size of the filter. I’m fairly certain the current pump is 1.5 hp. Also. We’ve been tossing around the idea of removing and replacing with an in ground, though not this year. Is there a filter pump combo we could get for this pool that could transition to an in ground? Thanks so much!
