I'm guessing it is in the bottom, but it wasn't stirred up when
you tried draining from the bottom. Filling just the bottom and
emptying it a few times might do it. Does it have any kind of
access panel such as immersion heater tap that you could look in
when it's drained down (or drained below the access panel)?

No access panels. I think the main problem is that there is no separate
drain point and the lowest accessible point to drain it is the cold water
inlet which is about 18" up the side. I suspect the only way to do this
might be to syphon it down with a hosepipe inserted in the top but that's
going to involve disturbing quite a lot of soldered pipework. :-(

I have visions of having to remove the cylinder, so you can
give it a good shake and sloshing out.
And then compression fittings, so it's easier to do next time;-)

Also a good excuse to buy one of those colonoscopy cameras from
Aldi/CPC/Maplin, if you haven't already...


I noticed that CPC were selling one with a USB I/f for £20-30 a couple
of weeks ago

(I bought a chainsaw - watch out world !)
