Report "The rubber stopper blocking the internal water tank has broken and I need a new one. Does anyone know where I can get one, or what size stopper I need so I can ask my DIY store? I phoned Amcor for help, but they were rather unhelpful saying they wouldn't ship a replacement as the costs were too high (even though I offered to pay all costs + something extra.) Without the stopper the unit is useless as I have no surface strong enough to take a unit of such great weight. Argh!"
