My 10 year old Hayward 1 HP pump has been leaking for almost year and is now sending out a high pitch howl so it's time for a new unit, which I hope will actually be a lot more efficient and a lot quieter in normal operation. We had the pool refurbed back in 2005, including new 2" PVC from the skimmer/main drain and a 1-1/2" line from the cleaner. At the time I didn't realize the Hayward was only 1-1/2", otherwise I would have replaced it.
I was considering the Pentair Whisper-pro line but the local shop where I get my chemicals recommended a Sta-Rite Max-E-Pro product. What experience with or knowledge about the pros and cons of these two pumps do folks here have? I realize they are now both made by the same firm, Pentair, so I am guessing they both have their own following.
One thing that impressed me about the Sta-Rite was that you can access the impeller housing by simply removing a stainless steel clamping ring...can't get much easier than that for future maintenance.
Price wise, they are basically the same, so it's down to quietness, efficiency, reliability and ease of maintenance.
