Please see the picture, these radiators must be 15-20 y.o.
I managed to remove one (top one) by pulling it off, but part of the screw was already exposed and, I believe, I broke some small plastic bit from the inside by doing so.
I really fail to see which screwdriver I could use to unscrew the others (like the bottom one), the screw is perfectly round inside with no head.
Also, is there a way to change just these plastic caps (leaving the old pipework) to the basic ones that b&q, wickes etc. sell e.g. http://controls4heating.co.uk/images/TRV PACKING1.JPG, they do not seem to be using this small fixing screw approach ?
Thanks!
