I was wondering if it is normal that there is a pressure beam of water coming out from the toilet's siphon. And also, what I should do to fix this? I have the feeling this should not happen during 'normal operation'.

I tried tightening or losening the ring, but when I do, either the beam continues, or the beam stops, but still water is flowing into the toilet, even though the water reservoir is full.

Under normal circumstances, the water source should react on full/non-full condition. In your case, I'd try to disassemble the unit to make sure there is no rust/salt/etc preventing it to stop the water beam.

Then, about the beam itself. It depends on a water pressure and effective gate size, however it affects the fulfillment speed only. Once floating bobber is high enough, it pushes a lever that intends to shut the water gate.

  • Thanks, the water beam seems to be solved partly, meaning, after a flush, there is no water beam, however, the toilet siphon doesn't stop when the water level has reached it's level. I cleaned it, and there was some dirt, but very little. – Michel Keijzers Feb 17 '19 at 12:35
  • Does it stop the water if you pull the floating bobber up by hand? – Yury Schkatula Feb 17 '19 at 13:02
  • No, instead the water beam starts, so the water level part seems to work, but still water gets out through a small hole (resulting in the water beam). Before the water level is reached, there is no beam, but the water goes down somewhere else (assuming that's the default way). – Michel Keijzers Feb 17 '19 at 13:18

    I am unfamiliar with this particular model of valve. Most toilet valves sold in the US have a soft "elastomer" seal which is available as an individual part. For those valves that is the only replaceable part that I know of. In the US an entire new valve assembly is fairly cheap and a common course of action is to replace the entire assembly rather than determining the exact failure point and trying to repair it. – Jim Stewart Feb 17 '19 at 15:15
  • Sorry for the late acceptance. After some try, I found out it was easier to buy en entire system, which didn't cost much anyway. Thanks for the help/insights. – Michel Keijzers Jul 22 '19 at 20:14
