Heater core flush

I've searched and can't find an answer to my question.

Can you flush the heater core while it is still in the car? Basically will it drain or do I need to get some extension hoses?

My heat isn't really hot but it is warm. I know it could be other stuff but I want to attempt this first based on previous experience.
