In helping a customer determine which was the best pump for him to use for his application, I ran across the following article, Pentair Pool Pump Comparrison, which really breaks down the differences between the Pentair 3HP Intelliflo pumps.
Another pool builder had recommend he use a Pentair 011057 which I had never heard of. In researching it, it has a SVRS system, which is a safety vacuum release system. Typically, I recommend the 011056 because it has all the features one needs plus it currently is the most economical out of the 011028 and the 011056. The 011057 is ~$200 more than the 011056 and has a feature that most new builds don't need.
Anyway, thought I would share for those that are curious about the different pool pumps.
