Hi, I'm trying to top up the pressure on my Vaillant combiboiler (Ecotec Pro 28).
I've watched a few videos and I think I know which pipes to connect with the filling loop, but I'm not sure. I tried and the pressure didn't rise, although I don't think I heard water flowing like in the videos.
The pipe which the water comes out of when I turn the tap is labelled as "C H flow" with an "out" arrow, and the water smells and is hot. Is this the right pipe?
I connected it to the "cold water mains / cylinder return" which has an arrow pointing in.
Any advice would be helpful. Thank you!
