Just removed a radiator from the wall, I thought both valves were closed as i was able to drain it fine and remove it with nothing pouring out of the pipes. However when I went to re-pressurise the boiler water came rushing out of the thermostat valve side. It goes from 'max' to '*' with no '0' setting so I assumed it was off which it clearly isn't. How do I shut the thermo valve side properly?
