Sorry if this isnt the right place to post. I have recently moved into house and the boiler has not been used for a long time so it needs topping up - pressure is well under 1 but I cannot find how to do this and dont have a manual. I checked on FAQ and found the filling loop picture nad thus the filling loop but one end has a screw driver slot the other a nut - neither has a lever. I know that this may be dense but how do I fill this up?
Thank you
Thank you
