Heya, as you can see the question is stupid, and this is maybe not the /r/ but i couldn't find an answer on google, tried with a few different phrasing... I'm just at my brother's temporarily and he had shut off the radiator but it's gotten kinda cold now and i want to turn it back on :D But the thing is that the exit valve (not the big one with the 1-5 numbers, but the one on the other end) is broken, what i mean by broken is that not the valve itself is broken, but the plastic knob that actually turns it. I have no pliers/tongs.... It's one of the 4-sided flat surface ones not the one with a lot of little "teeth".... Any idea what i can do at home to fix this? via /r/DIY http://bit.ly/2Tr9AMO
