Grundfos issues

[jreinke]

Hey yall,

My grundfos is making a constant rattling sounds - i have never encountered this nor is there a youtube of it.

Wondering if i should buy the same one to replace it, or if there is a better model, or if the models are even interchangeable.

I like in a 3 story townhouse.

I'm pretty handy, as in I can comfortably clean out tankless water heater, install dishwasher, etc... will this be manageable or should I call in an expert?

Appreciate teh help,

-J

That seems to be 18 years old. I would replace it, since they do get worn out occasionally.
