Why should I pour oil down the sink?

Immediately it should say that this is not my idea and I went trick "inherited" from my father, so that the method has been tested by two generations of people! I'm so used to it that he always thought that it is aware of all the people, but recently asked me about this friend and I decided to tell you, and I hope it will be useful :)

Get to the point - why am I doing this?

In fact, everything is simple and butter allows me to get rid of the unpleasant smell of sewage when I'm leaving for a long time in the city and in the country no one lives. As a result, the water in the trap under the sink can evaporate over time, and the smell of sewage fills your home.

The oil also has a lower density than water and is always on top, creating a protective layer, and preventing its evaporation. If you constantly live in the house, in the siphon (or fermentation lock) always have water and you do not need oil. But if you are going on vacation or to the country, it is highly recommended - only 30-50 ml of vegetable oil in your apartment is not even a month to smell like a garbage!
