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?

Because it's not a 1" lockshield with drain off :banghead:

It doesn't matter what the technical description for the valve is, I took the original one into the plumbing merchants and they said they had never seen one before with that sized thread on the radiator outlet!!

You have a screwfix and a b&q in Abingdon suggest you try either of them, b&q will have them out on display.

I didn't say it was a '1" lockshield with drain off '. In fact it is a 10mm radiator valve with drain off which can be configured either as a lockshield or a manual valve as described on the packaging but it has a 1" thread on the radiator connection.

But that's not the rad connection, it's the connection on the Union

AWJD, it is made up of 2 parts, the 1st part screws into the radiator on a tapered thread then your valve connects from this part via the large nut to your 10mm pipe.
