New to the market from Geberit is the Sigma70, featuring Hydro Server technology. Said to be simple to fit with no tricky electrical work required, Sigma70 can be used for new installations or upgrade projects alike. Made from a single piece of glass or stainless steel, the flush plate uses a combination of pneumatic and hydraulic power for the flush, which is triggered by the lightest of touches. A slight push on the left side of the plate flushes solids clean away, while gently pushing on the right side flushes liquids.
