Presumably a dual flush siphon doesn't have this problem, for example: https://www.vivasanitary.co.uk/news/how-a-dual-flush-syphon-works.aspx https://www.vivas

  The UI can be quite confusing for these though as it’s not at all obvious that “flush and hold down” will yield different results or that the result will be less water used. I think I had one cistern that was siphon based (guessing based on needing to push the button hard) but had two buttons for different sizes of flow. Then again, it would often fail in a way that made me think it wasn’t siphon based.
