The fill valve is likely the most sophisticated part of the cistern. Comprehensive tests conducted in Geberit's acoustic lab identified and addressed noise issues caused by traditional fill valves. The water inlet has been designed to minimize noise propagation in the supply line. The extended downpipe ensures silent filling below the water level. Geberit Unifill, classified as acoustic-grade, has earned the NF certification.
To further enhance near-silent soundproofing, Geberit activation systems are equipped with small rubber seals that dampen the noise produced by mechanical components when pressure is applied to the control plate.
The cisterns are designed and tested to withstand loads of up to 400 kg.
