Geberit Series 290 Dual Flush Mechanism d40

The Geberit series 290 d40 dual flush mechanism, reference 282.302.21.2, is an innovative and efficient solution for ceramic cisterns, enhancing water consumption control and management. Manufactured by Geberit, a leader in sanitary solutions, this mechanism is designed to be compatible with ceramic cisterns with a ø 40 mm hole, offering excellent functionality and reliability in use.

The flush mechanism includes an adjustable dual flush, allowing selection between a full or partial flush, helping to save water by adapting the flow to the specific needs of each use. Both the full and partial flush can be adjusted according to the amount of water stored in the cistern, thus optimising resource use. This efficient design not only contributes to environmental sustainability but also helps to reduce water consumption in homes or commercial installations.

One of the most notable features of this mechanism is its adjustable height, which facilitates its installation in cisterns of different sizes and models. The overflow pipe can also be adjusted in height, allowing greater flexibility and customisation of the installation. This adjustability ensures that the mechanism can perfectly adapt to a wide range of cisterns, regardless of their configuration or capacity.

The Geberit flush mechanism is designed for use with both potable water and greywater (rainwater), provided a filtering system is used to maintain the pH between 6.0 and 9.5. This makes it an ideal option for systems aiming to utilise rainwater to reduce potable water use in toilet flushing.

Compatibility and applications:

This mechanism is compatible with the flush mechanism baskets of series 280 and 250 (Twico 1), meaning it can be used as a replacement or upgrade in installations already using these systems. Compatibility with different series of baskets facilitates its integration into renovation or improvement projects of existing cistern systems.

Additionally, the Geberit dual flush mechanism includes a cistern lid fastening system, ensuring a secure and hassle-free installation. Thanks to its robust design and the quality of materials used in its manufacture, this mechanism guarantees a long service life and reliable operation for years.
