The solar rain water level reads 100%, but what if the overflow pipe overflows?

Hello! This shows that the highest end of the overflow pipe is slightly lower than the highest water level when the water is full, the top of the overflow pipe is slightly lower, so overflow will occur will produce however. The water tension is not very low, the water will overflow. The water level gauge (which is inherently inaccurate) also shows it's almost full! ! !

It is recommended to add a piece of hard pipe to the end of the overflow, or when adding water, do not fill it as full as a Gade, it should go!!!
