Friends have one of these , installed late 2012. They say they were told by an RGI it was OK to leave the plastic key in the manifold in the locked position. Surely this is wrong? The WB video on YouTube says when you withdraw the key, some water may leak out. I see the key has 2 "O" rings on it so presumably it seals in the manifold? Where does this water come from?
The boiler was down to 0.5 bar yesterday, could the key being left in cause the problem?
I've had a look at the instructions but it doesn't include the internal filling loop.
