    Leaking joint on Aluminium radiators

    Hi, Where the valves screw into the aluminium rads has started to leak (all be it not that much). The system is a ordinary pressurised sealed system. The leak is hardly enough to drop the pressure. The system has been fine for 4yr+, I guess that the rubber gasket has started to fail. I have...
