Fitting A Telescopic Radiator Tail, in the real world

** I am not a plumber. I do not take any responsibility whatsoever for the information in this video. If in any doubt, consult a professional plumber. ** My old radiator was imperial, the new one is metric. There is now a gap between the old valves and the new radiator. I could not work out how some 'Radiator Tail - Telescopic' systems worked when looking online. I fitted one and it leaked. This one worked first time, so you save someone else about 5 hours, heres the video.... taken by my six year old....
