Morinaga Engineering Ventilation Valve Mini Dolgo for Kitchen Sink MDK-40N

[Prevents odors and gurgling noises caused by insufficient ventilation] By installing the mini dolgo, air is smoothly drawn into the drain pipe, improving the drainage environment. *However, it is not effective for problems caused by positive pressure caused by double traps, reverse gradients, and blocked drain pipes. [Double backflow prevention function] Even if the drain pipe becomes clogged, the double backflow prevention function prevents water from flowing back into the drain pipe.

Mini Dolgo is the first product in Japan that makes it possible to install sanitary appliances under the overflow rim. By preventing water seals from running out of equipment traps, unpleasant odors and sounds are prevented. In the unlikely event that the drain pipe becomes clogged, the double backflow prevention function will prevent the backflow of wastewater. There are two types for each (4 models in total), one for the kitchen sink and one for the handwasher.
