The part that is actually running, not the whole cistern · review
The only fill valve in this catalogue that publishes a fill rate and a noise figure — and the only listing that tells you which cistern it does not fit.
The bottom line The valve for a quiet flat, and the most honest listing in the hub. Slow filling is the price of silence, and it is stated.
A compact float-operated fill valve with a stated fill rate of 3.6 l/min, a noise level of 13 dB(A) in noise group I, a brass connection spigot, snap and push fittings, and a steplessly adjustable float.
3.6 l/min. A deliberately slow fill. That is what makes it quiet, and it means the cistern takes about two and a half minutes to be ready again rather than one.
13 dB(A), noise group I. The quiet classification under the German standard. If your bathroom shares a wall with a bedroom, this is the specification that solves the problem.
“This item does not fit a TECE cistern.”
Concealed cisterns are brand-specific inside. A valve that does not fit means the panel comes off twice. Naming an incompatibility in your own bullet points costs sales, and it is the most useful line on this entire shelf.
The thread size on that brass spigot, and the inlet position. Take the old valve out and look before ordering.
On sale from 17 € to 21 € on the German, French, Italian and Spanish Amazon stores at the time of checking.
Also on sale on the American and British Amazon stores, in the local currency: the range above is measured on the euro stores only.

The quietest classification under the German standard for sanitary fittings. A cistern refilling behind a bedroom wall is one of the loudest things a flat does at night, and a valve rated in group I at 13 dB(A) is a specific answer to that.
Because concealed cisterns are brand-specific inside, and a valve that does not fit is a wasted afternoon behind a wall panel. Almost no listing admits an incompatibility. This one names it in its own bullet points.
