Saved a few hundred dollars with this rebuild kit
This kit was ordered to rebuild a Grundfos MQ3-45. The Supply House team answered some technical questions I had, and I received it quickly. The kit contained exactly what I needed to rebuild the mechanical side of the pump (there was nothing wrong with the motor or control unit).
The only thing not included was assembly lube, so make sure to get some of that separately.

Grundfos = quality
this rebuild kit is worth the money!
I've tried other booster pumps - switched back to Grundfos after a few weeks
