Geberit flush valve type 212, 4.8/3 liters, for Sigma, Delta and UP300 concealed cisterns 244.822.00.1

Functionality and Universal Application in Sanitary Installations

This complete control element has been designed for precise water flow regulation in modern concealed cistern systems. Its primary function is to ensure effective flushing while minimizing water consumption, achieved through the ability to select between two operating modes: 4.8 liters for standard flushing or 3 liters for an economical cycle. This division allows flexible adaptation of operational parameters to individual user needs and installation requirements, without the need to replace the entire device.

The device features wide compatibility with popular mounting frames and Geberit systems. It operates seamlessly with models from the Sigma, Delta, and UP300 series, making it a universal solution for both new installations and the modernization of existing systems. Installation takes place directly inside the cistern housing, where the valve plays a key role in the control mechanism. Thanks to its construction, this element guarantees stable operation over a long period, minimizing the risk of failures related to leaks or incorrect water dosing.

Key Construction Features and Operational Benefits

Several important aspects distinguish this model from other solutions available on the market:

• Two-stage water economy – the ability to set two different doses (4.8 l / 3 l) allows for a real reduction in utility bills without compromising toilet usage comfort.
• Complete readiness for installation – the product is delivered as a complete set, eliminating the need to purchase additional accessories or gaskets during installation.
• Wide compatibility range – one valve type supports three main series of concealed mounting frames (Sigma, Delta, UP300), simplifying logistics and spare parts storage for professionals.
• Precision operation – the valve mechanism has been refined to ensure repeatable water doses with every flushing cycle.

For installers, this means less time spent selecting appropriate parts and faster completion of installation work. For end users, it guarantees reliable operation of the sanitary system and water savings over the long term. The device construction has been designed to withstand frequent operating cycles typical of public facilities and single-family homes.

Practical Application and Operating Conditions

The valve is primarily used in bathrooms equipped with concealed WC systems. It is an ideal solution where aesthetics (absence of visible mechanical elements) and functionality are priorities. Thanks to the possibility of installation in Sigma, Delta, or UP300 frames, the device performs well in various interior designs – from modern apartments to offices and commercial buildings.

Keep in mind a few rules during its operation:

1. Before commissioning, verify the correctness of the hydraulic connection and the tightness of the joints.
2. Water dose settings must be performed according to the manufacturer's instructions included in the kit or the technical documentation of the cistern system.
3. In case of maintenance or gasket replacement, access to the mechanism is facilitated by the standard Geberit system construction.

The main parameters of this model include operation with two water doses: 4.8 l or 3 l, and full compatibility with Sigma, Delta, and UP300 systems. The device is delivered as a complete mounting set intended for concealed (hidden) cisterns. Thanks to these features, the valve constitutes a reliable link in the liquid waste disposal system, combining ease of use with high technical performance. It does not require complex service procedures, and its service life meets the expectations set for Geberit brand products.
