Sanitana Reference Projects
Conventional toilets account for more than 30% of domestic water consumption, as they typically use the full volume of the cistern even when this is not necessary.
To address this issue, all Sanitana cisterns feature a dual-flush system — 4/2 L, 4.5/3 L or 6/3 L — allowing the user to select only the amount of water needed for each use, avoiding unnecessary waste.
The user can easily choose the flush volume through two separate buttons, designed for intuitive and practical operation. One button activates a partial flush, while the other triggers a full flush. This simple system significantly reduces water consumption without compromising flushing performance or efficiency.
This feature is available across all Sanitana cisterns, including both exposed systems and concealed installations for wall-hung or floor-standing toi
Equipped with a sealing system that controls the tank filling cycle, preventing refilling from starting before the flush cycle is complete. This optimizes the mechanism’s performance and minimizes unnecessary water consumption.
Compatible with most ceramic cisterns featuring a Ø40 mm hole, our universal flush mechanisms include a +/- symbol push button for a more intuitive dual-flush operation.
With an adjustable height ranging from 336 to 400 mm, our universal flush mechanisms adapt to all ceramic cisterns. Compatible with the previous generation, they can be replaced quickly and easily without dismantling the cistern¹ — simply twist and lift.
Designed for enhanced durability and reliability, our fill valves incorporate filters, non-return valves and flow restrictors that provide greater protection against failures and ensure compatibility with lower-quality water. The hydraulic shut-off system guarantees quiet and efficient operation under any water pressure conditions.
GREATER WATER SAVINGS Our universal fill valves feature fast and quiet filling, combined with a dual float and integrated delayed refill system that prevents water from entering the cistern during flushing. This reduces water consumption and allows savings of up to 1 litre per flush.
COMPACT AND ADJUSTABLE More compact and efficient, our universal fill valves adapt easily to any ceramic cistern with either bottom or side water inlet. Their wider adjustment range ensures simple installation and precise adaptation to different cistern configurations.
