    Pentair WhisperFlo WFDS-28: repair or replace?

    My Pentair WhisperFlo WFDS-28 has been making noise all season. It makes noise like it has loose parts inside and also vibrates. Bearings maybe???

    It is 10 years old. Should I repair or replace?

    Repair: replace bearings?

    Replace: just the motor (and a seal kit)? or replace the whole pump assembly (but then I would need to re-plumb?)?

    Any recommendations?

    Amazon has new whole pump assembly for $710.

    inyopools has new motor only for $390.

    Thanks in advance!

    Consider upgrading to a 2 speed motor. There is not usually a need to replace the entire pump.
