Please look at my above video. Do you think I should just run it on 2 or do I need to get it replaced?

I think the link might be wrong unless you are using a roomba as a pump
Found the correct vid. If you have technical knowledge drain system and open pump, sounds like something in it or blades failing.
I would say get fixed asap as it's probably not going to fix it's self and will probably fail at worst time possible.

Noisy pump is sign of failing pump. Investigate reason for failure, which on an open vent system is usually air in system due to blocked cold feed or clogged air separator. Bleed pump and, if system performs, leave on 2 until opportunity to investigate further.
