    This valve has reached the end of its life and was leaking underneath where it's now covered in black RTV silicon. As said, the problem in replacing it is that it appears to have a 1" thread on the radiator outlet which must have been common when I fitted it 15 years ago. This size fitting no longer seems to be available unless someone knows better?

    I have now been to both the main plumbing merchants in Abingdon (Grahams and Plumb Centre) and nobody in either had ever seen a Lockshield valve with drain with a 1" thread to the radiator. The guy in the Plumb Centre said he'd worked there for 25 years and never seen one even though my radiator is only 15 years old.

    How come I can then walk into Screwfix of all places and buy one over the counter as recommended by you guys on the forum? It seems to be a standard size for Screwfix but to nobody else in the industry?
