Independent cleaning
In many cases, you can do your own, especially if you do it regularly. As a rule, clogging occurs due to sticking fats on the walls of the pipes. For cleaning, you can simply boil a bucket of water and pour into the sink. If this was not enough, a cable will come to the rescue. In general, cleaning the sewage system in the apartment solves the problems only locally, because the central pipeline can clog in high -rise buildings.
