Often the reason why water in the sink drains slowly is because the pipes are clogged with fat.
This type of blockage is distinguished by the fact that it is very difficult to remove using standard cleaning products.
You have to be cunning and use other means.
However, there is no need to buy very expensive gels or powders. It is quite possible to limit yourself to using water. But not plain water.
The water that you plan to use to clear the blockage must be brought to a boil.
The still bubbling liquid should be poured into the drain hole.
The result of this simple procedure should be cleaning the pipes from fat. As a result, the water will start to leave the sink again quite quickly.
There is an important precaution to remember when performing the procedure.
Boiling water should be poured into the hole gradually. If you rush, the boiling water may "shoot out".
This often happens due to the presence of a so-called “air lock” in the pipe.
As a result, the person trying to clear the blockage may be seriously injured.
Thus, the hot water should enter the hole slowly. In this case, the pipes will be cleaned without any troubles and dangers.
