Magiplug is a unique bath and sink safety plug that reduces the risk of scalding and flooding using a pressure activated system. When an unattended bath reaches a certain depth, the pressure plate opens and releases excess water down the plughole to prevent flooding. When desired level is reached, pressure plate will close again leaving a filled bath. Changes colour between 32 - 41C as a warning that water may be too hot. Ideal for anyone likely to forget to turn off the taps. Attaches easily to your existing plug chain. Also available in attractive chrome style finish for the bath.
