When our pool was built in 2011 the original installed pump was a Jandy Stealth SHPF2.0 (2HP). It lasted till 2017 and then it was replaced by a Pentair WhisperFlo WFE-6 (1.5 HP) now this one is starting to fail and I would like to transition into a new variable speed pump. I'd like to stay with the Pentair brand because all their IntelliFlo models share the same volute with the WhisperFlo ones and thus will make the swap out much easier. Can you suggerst which IntelliFlo model would be my best choice for the replacement? Since the original Jandy was 2.0 HP and the Pentair is only a 1.5 HP is that lower HP rating a possible cause for it lasting a shorter time than the Jandy?
