Hello, I have a Valliant 182e boiler which I need to top up with water as pressure is too low. I cannot find the 2 valves on the filling loop though. Maybe there's another way to do this, but I am afraid to break something. These photos show the pipes bottom to top. Please help!
Only one valve to open ,on the right hand side of your pic is the braided ,flexible ,hose with a black lever
( Partially obscured) that's what you turn.
The black lever may be cracked( common problem) and not turning the spindle below it . Remove the lever and examine ,spindle can be turned with a spanner.
