Hi,
Due to a leaky rad valve the pressure on our combi has dropped. The valve has now been fixed and I need to top the system back up again. My plumber did show me how to do this when it was originally installed but its been a while and I can't remember exactly how its done. Does anyone have a step-by-step guide on how to do this on a Worcester Bosch 30si combi?
Thanks,
Paul
