When you clog the sink, use soda and vinegar!
You do not need to call a plumber to deal with a serious sewer clog. Experienced hosts have discovered simple improvised tools such as soda and vinegar.
This method is excellent because it does not require separate vessels to prepare the cleaning solution. The soda and vinegar are poured directly into the tube.
First, pour about half a glass of baking soda. And immediately pour the same amount of vinegar.
Put the sink cap tightly. The pi reaction will release gas, which is better directed inward.
You have to wait a few hours and pour hot water into the pipe. This method eliminates even serious blockages.
