I just installed (3 days ago) a brand new Hayward Max Flo VS pump. The pump is great and I love the ability to adjust the water flow on a whim. Here is my issue I noticed this morning when I went to turn the pump on. When the pump first starts it has a slight squeak for about 5 seconds. It does it as it ramps up from 0 rpm through about 800 rpm then stops and sounds perfectly normal. It also does it when you shut it down but it only does it for about 2 seconds on shutdown. The squeak is not that loud but you can hear it. I am trying to find out if this is normal for the variable flow pumps or if I need to contact Hayward for this issue.
