Hi all,
I need your help. I have a new Grundfos UP 26-96F on my system and I have noises in the two nearest hydroheating radiator. I made the pump work for 2 hours after which I stopped it in order to remove the air in the system. There is no air anymore and I still have that noise which is like a running tap.
Please help me, I do not understand what it is going on.
A big thanks,
