Discuss Why is the Trv leaking after removing radiator in the Plumbing Forum | Plumbing Advice area at PlumbersForums.net
yes and tighten the collar down then switch / turn the trv off but don’t do it now else you will flood yourselfFair point. Is it best to take the trv head off and unscrew fully to an open position from * to 7 and then replace back onto the needle head at position 7bwhich is fully open?
Yes these are from 1996, valliant.A 3/4 blanking cap should fit that thread but I cannot absolutely guarantee that. Like Shaun says, I too have never seen a 3/4" TRV outlet in a house before but there it is, looks like that's what you've got.
