When the hot water is on I can hear air going through the pump and also through the pipes in the airing cupboard where the megaflow tank is.
I know how to pressurise the central heating system and would bleed the central heating system through one of the radiators.
I know to re-charge the air bubble in the tank itself I would switch the incoming water off and open a tap.
What I want to know is how do you pressurise and bleed the hot water circuit?
