Main highlights

Toilet cistern with adjustable flush volume (6 - 9 litres) via adjustment on the float. This allows you to limit the inlet of water and it is used less.
The toilet cistern is condensation insulated and quiet when refilling. With integrated polystyrene insulation to reduce noise when filling. A tip: if it is still too loud, it is because you have the tap too wide open for the inlet. Reduce this so that the water flows slower and automatically the noise level is further reduced.
The toilet cistern can be connected on both sides - simply insert the built-in fittings inside the mirror inverted and you can adjust the cistern so that it fits your specifications (left or right). The toilet cistern is compatible with all standard toilet systems.
Surface-mounted toilet cistern: you will receive everything you need for installation. Cistern, filling valve, flush pipe, gaskets up to dowels and screws (please watch the video so that you can assemble them correctly to ensure 100% waterproof).
Please refer to the installation video to get a 100% result. The video can be found in the pictures here on Amazon.
Cistern with flush-stop function - cost savings due to lower water consumption.
