My radiant heat high head 26-96f Grundfos is about 12 years old and I am getting some vibration. Bearings getting tired.
I can get an eqiv. taco for about 215$ or get a new Grundfos cartridge for 120$. I know if the stator is scored, the pump is shot, but in no mood to take it apart without a ready replacement. Still pumping fine.
Opinions? Check amp draw to see if over specs would determine bad stator?
They can be had for about $180 at other sites.
