Watermom, one of the other mods, has a 24' AG with a 1/2 hp inground pump, and she says it works well for her. I have no idea about the 2 speed pumps or what it will take to replace it--hopefully one of the others will chime in soon that have some experience with it.

Just out of curiousity...I had my IG pump replaced this past summer with a pump made by A.O. Smith, which I had never heard of before. How many swim seasons did you get from your pump?
