TapMagic is a easy to fit solution for cutting water use in buildings. Simply screw into the tap to convert your tap to a Magic Tap. On low flows the tap will produce a spray (saving up to 70% of water), but if you need to fill the sink simply turn the tap on more and it will revert back to a full flow. Brilliant. Comes in three fittings - 22 and 24mm screw and 15-19mm push fittings.
