Review on Sewer installation AquaTIM AM-STP-600 (600 W) by Micha Osiski ᠌

I didn’t see what kind of chopper there is, I think it’s just a pump impeller. I think they are all noisy, but I do not like the drain algorithm itself. A full tank of water is collected at the station. Then the pump starts for 1 second, with noise. Dumps 1 liter into the drain and waits until the station is full. That is, he does not empty the entire station with a cut, but only 1 liter and freezes. If water from the tap is constantly pouring, then with such second noisy spitting he throws off 1 liter of water
