What is the reason for the abnormality of slow water intake into the toilet tank?

There is a water pipe control at home! I turn it off and remove the inlet valve for a wrench and clean it

When the small button is pressed, it consumes three liters of water to urinate and the large button is pressed, and six liters of water is consumed to flush the stool.

You can change the inlet valve, go to the nearby store that sells toilets, water tank accessories stores or building materials stores to take a look and ask to buy one, the water inlet valve can be divided: float type inlet valve (about 10 yuan), lifting water inlet valve (about 15 yuan), the lifting water inlet valve is better, the water level of the water tank can be adjusted, and it will not affect the drainage valve. When removing the original inlet valve, remove the iron nut of a hose connected to the outside of the water tank with the plate head, and then remove the plastic nut at the bottom of the outside of the water tank (not at the bottom of the water), and the new inlet valve can be installed according to the original method, which is very convenient.

When there is no water in the water tank, the float lowers and opens the valve to start replenishing water, and when the water reaches the limit height of the float, the valve is closed.

The nut of the pipe under the inlet valve is removed, and it can be pulled out.
