Anyone got any ideas on emptying the pipework? I can cut into
it under the floor (actually, the reason for draining it is
to move towel rail connection to it, so I will be cutting
it anyway). Obviously don't want it pouring through the
ceiling below though, as it's literally just been decorated.

Would it be feasible to feed a long length of narrow flexible tube (I'm
thinking aquarium aerator-type) down a radiator tail as far as you can
and syphon it out?
