Complete novice here - so please excuse if these seems stupid questions
However would appreciate any help from you experts.
Have seen referene to a vent valve on the CH pump. What does this look like? May it be opened/closed?
Also ref seen to anti-gravity valve near boiler - also a diverter valve somewhere. Where are these usually located? and what do they look like? May they be disturbed? Any diagrams?
