Hi all, I've had low pressure on my boiler a few times and just used the filling loop to sort it. However, now I seem to have a high pressure isssue. I've managed to get it out of the red by bleeding from a radiator, but as part of the checking the issue I've looked at the filling loop and I'm not sure if it's fully open or fully closed. Can anyone tell from these pictures if it's open or closed?
Thanks
Thanks
