Toilet outlet valve loading and unloading method @ Zhang Zhichen 100 refining experience 50

Absolute personal experience: The toilet leaks and a tank of water doesn't have a drop of water left overnight. Searched the Internet, a lot of experience, but none of the use. There are many people who ask how to unload the water valve, but the answer is: find a professional, their own unloading is broken, pull down, replace... And just take the waterproof off. As a result, I'm still overwhelmed. However, I am the person who has a famous saying: Can't fix it still fix it? So he forcefully turned the water valve and finally brought it down. Look at it, my God, so simple: first, the appearance of the water valve: [meaning that this thing is the water valve] Second, there is a white protruding in the middle of the gap, the size of the corn kernels [in fact, it is in a slide] Close look: vertical direction and look again: [under the blue material, near the left water] Third, the upper part of the rotating water valve: it can actually move! Look, the white bulge has slid to the right! Four, in the vertical direction of the slide upward pull: five, separate the appearance: six, from the top down, there is a screw in the middle: seven, the cause of the water leakage to find: screw maneuver, only it is tight: Result: if I had known this, there is no need to the whole water valve hard twist down.
