I need some advice on the best way to drain down my CH system to add
an additional radiator. I'm in a first floor flat and the pipes run
under the wooden floor. There is a drain cock on one of the radiators
but correct me if I'm wrong this will only drain to the level of the
drain cock? All the pipes under the floor will still be full of water.

Does it matter if the pipes under the floor are full or water?

If the water is drained below the level of the radiator, there won't
be any spillage when you disconnect it.

A big car sponge is useful for catching drips!
