Toilet water leaks into the tank, and when it overflows, it leaks into the toilet

According to the figure, this type of toilet is an old-fashioned toilet, and the reason for the leakage is simply that the rubber gasket that presses the water inlet pipe is broken. The whole set of water tank accessories can be bought in ordinary hardware stores, very cheap at about 10 yuan, if you want to repair, it is recommended that you first remove the float (you can also remove the nut at the bottom of the tank and the hose, take out the water inlet pipe in the toilet and then repair), and then hold the water inlet pipe with your left hand to prevent it from turning, and hold the top of the water inlet pipe with your right hand (the part of the circle connected to the float rod) can be disassembled by turning it counterclockwise, to see if the rubber pad inside is worn and cracked, if it cracks and find a way to make it yourself, If it doesn't crack, only if it's worn, turn the rubber over, as long as the next side is smooth and not cracked, it's still easy to use, and then put it on as it is.

It's the inlet valve valve of the tank fitting that is broken, and you just need to replace it.

Use plastic cement to seal the toilet perimeter, drip leakage, and also repair tiles, metal, ceramic, and glass. After wiping the area to be mended, rub it into strips and stick it on!

Since the ball valve can stop the water when it is pulled up, it proves that the underneath is good (where the arrow is). The problem is in the big bump on the arrow, there should be small impurities in it, try if you can remove it and clean it, if it doesn't work, change it.

It is speculated that there is no problem, it is that the inlet valve is broken, it depends on whether you can buy accessories to replace it, and if you can't buy it, you will replace it with a new toilet.

To sum it up, it is... There is a problem with the water stop part of the inlet valve, you pour it yourself, it is better to contact the dealer where you bought it, although the warranty period has passed, the original accessories should have wow, and the inlet valve can be replaced again? I can only speculate on what went wrong by repairing it myself, and I still have to replace the accessories in the end, isn't it?

There is too much attachment in one position, which causes the water to be stopped by pulling the thin wire by hand, and there is no strength to automatically rely on the float to stop the water. Let's figure it out for ourselves.
