Reasons for the smart toilet flushing problem

There are many possible reasons for the smart toilet flushing problem, one of which is impurities entering the flushing valve along with the water flow, causing the flushing valve to become blocked. At this time, it is necessary to remove the cover of the smart toilet, remove the flushing valve for cleaning, and then reinstall the flushing valve to prevent blockage.

One important reason for impurities entering the flushing valve is that there was no drainage operation performed before installing the water inlet pipe of the smart toilet. During renovation, there may be dust, small stones, impurities, etc. hidden in the water pipe. 
Therefore, before installing the water inlet pipe of the smart toilet, it is necessary to drain the water inlet hose for at least three minutes to ensure that there is no dust, small stones, impurities, etc. in the water pipe before installing the water inlet pipe on the smart toilet. 
At the same time, it is necessary to use the angle valve equipped by the factory with a filter screen to ensure the removal of impurities in the water. Regularly remove the filter screen for cleaning to ensure that the filtering function is not affected.
