I'm a bit of a DIY novice, so was hoping that some of you may be able to help!
We have old skirting radiators (fitted in the 1960s) which are lukewarm, so I figured a bleed was probably the best place to start. I've attached a pic of what must be the bleed valve, as the other end of each radiator is a on/ off knob.
I tried a standard radiator key and it was too small. I have seen 'meter keys' which have a larger square key, but I can't get these to line up as there is a limited space from the top of the valve to the radiator housing, which doesn't come off as it's all plastered and painted in with the walls.
I am now trying sockets, and only had 8mm (which was too small) and 10mm (which was too large) so I'm planning to buy a 9mm one which will hopefully fit.
My question is... has anyone come across these radiators before and tried to bleed them? Am I going about it the right way? Any advice welcomed.
Also I read somewhere that hot water can be affected by bleeding your radiators. Is this true? Would it be better to bleed one radiator every few days rather than do a job lot (we have 10 of these things throughout the house)
Also, I read somewhere that it is best to start with the radiator furthest from the boiler, so perhaps upstairs first and then downstairs?
Thanks all!!
