Can I drain a radiator?

Question

I have one leaking radiator (rusted at the base) but my local heating engineer can't come out to it for a few weeks. Can I drain it while I wait for a repair? I have a combi boiler, so I assume it's possible?

Just shutting both valves down to off should air lock the radiator and stop and leak . But failing that shut both valves and crack a nut closest to radiator and drain in to a washing up bowl .

Hi turn both valves clockwise put a bowl under it and will slowly stop when radiator is empty

Yes you can empty it to stop further damage. Make sure both valves are closed properly.

Turn both valves off be make sure they are turned off as the valves do let by sometimes..crack a nut on the radiator tail and drain radiator down..I prefer using plastic bag.

You maybe able to just close both radiator valves clockwise and then just place a bowl underneath the leak till it stops dripping however some thermostatic valves do not shut off completely unless you have the decorators cap.
