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?)?
Amazon has new whole pump assembly for $710.
inyopools has new motor only for $390.
Thanks in advance!
