Bath & Sink plugs that prevent floods About Magiplug® See www.magiplug.com for photos (cant seem to cut & paste photos from websites ????). Also no prices of these wonderful little plugs - need to email company I think. Magiplug is a unique little device that allows the bath to be filled only to a specific level. Ever left a bath running only to return to find a flooded bathroom? The water damage caused by an overflowing bath can be extensive and costly. Sometimes taking months to completely dry out, Not to mention the damage to the rooms below. Magiplug® Is considered by many to be the best little plug in the world because of its unique features. It prevents your bath from flooding over and causing water damage to your property. It works using a pressure-activated system. When an unattended bath reaches a certain depth the pressure plate opens and releases the excess water safely down the waste exit or plughole prior to flooding, this level will be maintained until the taps are turned off. When the desired level is reached the pressure plate will close again leaving you a filled bath. Magiplug® Is available in a wide range of colours: including Chrome and gold. With the increased pressure on the plug as the bath fills, the unique mechanism opens and allows the water to flow away maintaining a constant level. Which means you never need to worry about thousands of pounds in damage as a result of an overflowing bath. Magiplug® NOW WITH A BRAND NEW DESIGN Making Magiplug even more streamline Also with a great safety feature, "COLOURTHERM" the plug will change colour according to the water temperature. Colourtherm is an amazing material that tells the user when the water is dangerously hot, By changing colour at about 32 - 41 degrees C This is a fantastic breakthrough in safety features and combined with its anti-flood mechanism Magiplug is a unique dual-purpose safety device that no self respecting property owner should be without.
