## Long description

VIEGA Viega 3821 is a freestanding cylindrical tank with an outer diameter of 165 cm, an inner diameter of 100 cm and a height of 900 mm. The tank is intended for situations that require a compact vertical storage vessel with a clearly defined internal volume and stable cylindrical structure. Constructed in two parts from plastic, the design provides straightforward installation and integration with standard WC connection components.
Advantages
The two-part plastic construction reduces weight while maintaining dimensional stability and resistance to corrosion. A clear marking for a 22.5° angle cut simplifies on-site adjustments and ensures accurate alignment with plumbing connections. The combination of outer and inner diameters gives a predictable internal volume suitable for installations that need a compact vertical footprint and reliable structural performance.
Suitable for
 Plumbing installations requiring a compact vertical storage vessel
 WC outlet and connection assemblies using WC connection elbow or WC connection pipe
 Industrial or utility installations where a defined internal volume and cylindrical shape are needed
 Sites where corrosion-resistant plastic components are preferred
