Many of the Taco circulators are designed so you can replace the motor and impeller as a cartridge. I haven't actually priced that verses replacing the whole thing. If you're not paying the labor, does it make sense to just replace the cartridge verses the whole circulator? What about if you are paying for labor?

The circulator for my indirect zone is starting to make some noises, so I want to have the parts on hand to fix one route better than the other? Or, would you pick a different brand entirely?

Thanks for any insight.
