I've previously installed TRV's and lock shields on new radiators but I am now attempting to do this on old rads. I assumed it would be the same process until a plumber was suggesting that the "tail pipes may need to be soldered". I think he was suggesting that the old copper pipe may not be the right size (certainly looks 15mm to me!) or perhaps he meant that its been tightened and hence, a new piece needs to be soldered on in order to make a clean fit. Sorry for the rambling.
Can anyone relate to this or give me a heads-up on what may await?
