I have decided to replace my pump with a Pentair IntelliFlo3 VSF 3.0. There is a reputable online retailer (1600 google reviews, 4.8 average) that will sell me the pump for $1600. I am waiting on additional local dealer quotes but so far have one at $3000, apples to apples, no install included. After looking at the Pentair warranty page it seems to me if I get it "professionally" installed and register the product my warranty coverage is identical to buying from a dealer. Is there anything I am missing in this?
