Magnaclean air vent

[Tally101]

HI All
On a Magnaclean air vent is it the square nut in the vent thats supposed to move or the whole round vent as on mine its the whole round vent that moves. When I tighten it back up it feels like its going tight then loose again. Should I replace it ?

The square part. It might have blinded slightly, so using your bleed key turn that one way and secure the nut with your tools of choice: spanner, grips et al.

I have ordered a new air vent as its leaking as its not tightening up properly. however I am still having loads of air after 3 weeks , I have automatic air vents in all upstairs rads , is there anything else I can do ?
