Water outage is often a water pipe repair project, by the repair of the vibration of many pipe wall rust will fall off and block your water pipe, because the toilet outlet is smaller, easier to block, you can unload the connecting water pipe, put water to flush off the debris, you can't ask a professional to deal with it.

See if your water supply line is clogging the sand, remove it and check it.

First of all, the water inlet valve can not stop the water, it may be that the water pressure is not enough, according to the structure of the water inlet valve, it is to use the water pressure to float the pontoon, and then use the lever to start the water stop device. Therefore, the water cannot be stopped floating on the pontoon, and it may be that the pontoon is not well adjusted, so that the water pressure is not enough. Either that, there's a problem with the water ingress.

Open the water tank, see if the float is not coming up, and adjust the position of the lower plug with your hands to see if the water inlet filter is blocked.

Open the lid of the water tank and move the water pontoon to see if it is stuck, and see if the angle valve below is open, it is okay, that is, there is a filter screen blocked in the water supply pipe between the angle valve and the water tank, close the angle valve and open it to clean it, and if you can't repair it, you can find the property department to repair it
