Actually very good - only the Hall sender

I've purchased the pump, after I had water in the basement. I found out after a long search that this occurs through the basement window. This year I was not able to revise, so I put a pump into the cell holder. The cellar was now Another month dry.

However, there is no "fire and forget" solution. The problem I see in this (as in probably all other pumps with Hall encoder sensor), the sensor may not function properly when dirty.

I have found the following behavior: The sensor triggers pollution (this is enough a slight layer of dirt) and leaves the pump through the sump until the electronics detect dry running and the pump shuts off. That would not be so bad if the pump would run on again. However, it can be brought out of this state only by pulling the power plug. Means: Next time sensor under water pump does not do anything. In my case I had the water back in the basement.

I have the next day brought the pump from the light well and solved the pollution of the sensor. Now it works again ... but probably only until the sensor again produces false signals. Already a pity that the pump (in my case) but then every week must be checked again. That's why I can not give full credit to the pump. A pump with float sensor would be there probably have been a better solution in my case.

The pumping power itself I would describe as good and the pump makes a high impression. After unpacking it has a strong smell spread (not to Köllnisch water or roses ...), but it is indeed there and now the smell is gone.
