Is it ok to put this on the start of the downstairs run on the 22mm pipe on
the flow side, just before the first radiator. Or must it go the 15mm
radiator pipe, or should it be on the return side?

TIA

Don't think it matters - it only has to be as low as possible. A
combination sort on a rad close to a door so you can run a hose outside
can be a good idea.

They should be fitted to all the lowest points, such that you
can completely drain the system. It doesn't matter were logically
that is in the radiator circuit. I always fit in the flow and
return at such points.

Or pick a spot along a pipe that is level with a gully outside, fit a
tee and an inline valve then connect it to a pipe that goes through the
wall. That way when you want to drain the system you just open the valve
- no need to mess about with hoses etc.

Sounds awfully organised to me. ;-)

In my case it required less organisation than trying to find a spare bit
of hose each time! ;-)

Anywhere on the lowest point. You might want to tee off the lowest point
and take a 15mm pipe to a position over say a gully, and terminate the drain
cock there. Then no hose pipe involved in draining down. Get a good quality
drain cock.
