    Penrair Challenger Different sound after shaft seal.

    I replaced the shaft seal on my Pentair Challenger pump yesterday. Everything went ok and the leak is gone. However either the motor or the pump has a slightly higher pitch sound to it now. Should I be concerned? Here is the video: April 23, 2016 - YouTube
