So after much procrastination I took apart the machine because it was being unusually load and discovered an air bubble in the area that I will attach a picture of. I believe it is coming off of the OPV but I'm not 100% sure where the OPV is or if I'm looking at the right thing. Its is coming off of the gold cylinder toward the back of the machine. When I turn on the pump you can see it bubbling inside the tube where it is circled. There was also an air bubble in the clear cylinder filter on the right as well. I'd appreciate some advice on what to check/replace. Unless this is completely normal in that case I learned something.

That doesn't matter. That's your priming valve, it's supposed to send any air that the pump sucks in out that direction to help the pump prime.
