What is the reason why the toilet potty does not get water

1) There is also a filter inside the toilet water filler, and the filter screen is blocked by too much limescale for a long time, so that tap water cannot come in. Just remove the strainer and clean it.

Remove the filter and clean the solution steps:

Close the valve on the hose that connects the water inlet to the tank, or the operation will spray water after a while. Flush the toilet again and drain the remaining water from the tank.

Along the water inlet hose, look at the bottom of the toilet, there is a hexagonal nut to connect the hose and the water replenisher (a standing plastic pipe) in the water tank together, turn the nut with a wrench, and then look up along the position of the nut, there may be a nut in the same position, the same turn, the same function, also unscrewed, after two processes, the water filler can be taken out from the inside of the toilet.

Take off the water replenisher, see that there is a small square column in the middle of the inner tube, and pull it out with needle-nose pliers, you can see that the square column and the filter screen are one, and they come out together.

Use a waste toothbrush or something to clean the filter. It's better to have a scale cleaner, no and it's not a big problem, I just use the scale remover to soak the filter for a while, it is very clean, you can also pour some of this mixture into the water filler, you can also remove the scale inside. All cleaned.

Finally, it can be installed back as it is.

2) The water in the toilet is automatically fed by water pressure, is the angle valve of the water supply not opened, or the water pipe is blocked? Or if the float can't fall, check the water tank.

3) Or is the main switch forgotten to turn on?

One is that the water pipe is blocked, and the other is that the float in the tank can't fall, please check the water tank.

I don't know what your question means, but you can ask the property to deal with it.
