My mother slipt and fell on the radiator last night and it has been leaking very slowly from the bottom of the valve. does this mean i will have to drain the system and replace the valve. is there a short cut? the rad is downstairs in the hallway and we have a combi boiler which is upstairs in the airing cupboard. The radiator is very old and the pipework is twisted and bent (but it was like this before she fell on it!)
it might just be a case of nipping up the compression nut a little tighter with a spanner.
if this does not work then it will mean a drain down and ptfe the thread (at the very least) or better still replace the valve (which you may as well do as you are draining down anyway). and if it's an old system it's a good opportunity to flush the system and add cleaner/inhibitor.
