I stand back, sipping a cuppa thoughtfully provided by my lovely
wife, admiring my two newly installed radiators sporting some of
the most complex pipework and soldering I have ever dared attempt,
and then it dawns on me.

I didn't put in any draincocks.....

Arghhhhhhh......
Can you not use these?

I'm surprised nobody makes a two-piece drain that just clamps around a
pipe and seals "from the outside" - fit and then take the drain plug
off and drill a drain-hole through the pipe beneath.

I'd be surprised if modern materials couldn't make it work. Heck, you
could even solder it I suppose. Maybe there's just no market for it.

.... but personally I'd go with Screwfix 12381 as suggested.
