I'm having some issues with my PMUP pump. It is running my carbon reactor. Every 3 or so days it starts to rattle and make a loud sound. I think this is when my carbon becomes clogged.

I used an MJ pump in the past and when the carbon is clogged the flow slows down dramatically the pump doesn't rattle this loud.

Is there something wrong with the PMUP or is there a way to detect when something is wrong and have the pump shut down? This was one of the major selling points and why I paid 800 bucks to upgrade.
