The question of how to unclog a main sewer line without cleanout is common, but many people don’t know what to do. Fortunately, there are several ways to clear this problem, including using a plunger. This method involves applying high pressure to the obstruction and forcing it to move along the pipe. If you’re not comfortable using a plunger, you should wear safety gear and protective eyewear. Sodium hydroxide is an effective chemical for removing organic materials from your pipes. To use this chemical, you should dilute it first and then pour it down the drain.
Baking soda is caustic, so it’ll break down the grease and blockage that’re clogging the pipes. To use this remedy, mix 1 part baking soda and one part vinegar. Then pour it into the cleanout opening. The mixture should fizz as it goes into the sewer line, so don’t wait too long. If you’re using vinegar, make sure to choose the one that doesn’t contain any colorants.
If a conventional solution doesn’t work, you can always try baking soda and white vinegar. This solution will react with the clog and break it up. After the mixture has soaked for about 15 minutes, you should be able to flush the blocked drain through hot water. You can repeat this process until the clog is clear. If the problem continues, call a professional plumber to solve it.
