Question

I just bought a Keurig home brewing system from Costco. It is Model B66. I know that the water reservior itself is made of plastic.However, I need to know, when the water leaves the water reservoir and goes into the brewer to be heated, is the water sitting in a container made also of plastic or is it sitting in something made of metal or glass while being heated.
