Viega Prevista 3L Concealed Cistern - 804664

Introducing the revolutionary Viega Prevista 3L Concealed Cistern - the perfect combination of precision engineering and innovative design for your floor-standing WCs. Featuring dual-flush technology, you'll have the power to conserve water at your fingertips. And with backflow prevention for added safety, you'll have peace of mind too. Not to mention that all components that are manually installed or movable are coloured yellow, making it an extremely installer-friendly solution. For example, the drain valve features two yellow sliders that allow you to easily change the partial and full flush volumes in 0.5L increments to suit your toilet pan.

But what really sets this product apart is that it comes with advanced German construction and is both WRAS and KIWA approved, so you can guarantee the highest standards and reliability each and every time. Add one of Viega's stunning flush plates for Prevista, available in a vast range of styles and colours, to give your bathroom a lovely finishing touch.
