Currently I have an approx. 11 year old Pentair Whisperflo WFE-26, 1.5 hp, 1.1 service factor pump that started making some noise at the end of last season and it was doing ok so far this season until recently and now it has become very loud. I'm leading toward just replacing the whole pump with a 2 speed pump. Is there much of a difference in the Whisperflo and Superflo pumps? It looks like the superflo 1.5 hp is about $200 less than the whisperflo, or at least it is here: http://www.poolsupplyunlimited.com/best ... 0043/69112.
Am I correct in thinking that since the pump motor has the high/low switch built into it that I wouldn't have to deal with any additional electrical work? Should it be simple to just disconnect wiring from the pump that is currently there and attach it to the new pump? Or is there something else I may possibly need to install it besides plumbing related items?
Thanks for any help & advice!
