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.

Fixed it. I may have forgotten to add draincocks, but I did add
isolating valves for each radiator. So I closed them off, closed off
the rad valves, which left me with about a metre of pipe with water in
it, instead of the entire upstairs circuit. Cut out a section, and
remade it - with a draincock this time. Took a lot less time the
second time round as I knew what I was doing, though admittedly the
end result doesn't look *quite* as nice. However, we'll probably
redecorate in a couple of years, so I'll have to pull the whole lot
off the wall anyway....
