I have the largest one... i think 220 and its a piece... i guess for the price it does whats expected but the venturi clogs all the time... i just ripped the thing out and put an air pump right into the intake of the pump. the smallest adjustment to the knob any your either 10'' below the cup or overflowing. i have it in the first part of my sump where the water level is consistent and it still decides to overflow sometimes.... save your money and buy something better.
