For more severe clogs, mix 50 grams of regular and soda ash and pour the mixture into the drain hole.
Next, you need to pour in 150 ml of 9% vinegar and chlorine (liquid chlorine bleach will do).
Close the drain hole with a stopper to prevent smell from entering the kitchen and leave for half an hour.
You can use regular baking soda powder - half a pack per toilet or drain hole.
Also, some recommend boiling a kettle, dissolving a pack in it and pouring it all into the clogged Soda + Vinegar pipe.
You can also use another recipe - add half a glass of powder and pour in the same amount of vinegar.
The most effective way to prevent blockages is to regularly diagnose the condition of your pipes and flush them periodically.
To do this, it is recommended to contact specialists who carry out tele-inspection and hydrodynamic flushing.
Cleaning the sewer system in a private home as a preventive measure is recommended every 18-24 months.
