Mental Simulation: After Pressing the Toilet Lever

Simulation target: a flush toilet. The process from the moment you press the lever, through the water going down, until the tank refills and stops. Don't look anything up — run it using only the mental image you have right now.

Close your eyes and build an image of a cross-section with the tank lid removed, then press the lever. From the moment you press the lever until the tank fills completely again and the water stops, describe step by step with numbers what moves in what order, inside and outside the tank. Then, at the very end, you MUST report the 'point where the image went blurry' — where in some part or moment the picture got hazy or you skipped ahead — honestly in one or two sentences.
