Just bought a bailey header tank. At the moment, I have a standard header tank with a braided hose going from the top of the tank to the top of the swirl pot.

Can I just use any hose between the swirl pot and header tank, like a normal vacuum hose or does it have to be a samco water hose or similar?? Is this just some sort of over flow??

Im not quite sure how swirl pots actually work and what they do??

Thanks in advance.
