Caustic soda can pass through the sewer, because caustic soda has a strong corrosive function. Caustic soda, that is, sodium hydroxide, is easily soluble in water and gives off heat when dissolved, which has corrosive effects on fibers, glass, ceramics, etc. Therefore, the fusion of caustic soda and hot water can corrode residues and dredge sewers.

during storage, caustic soda must be sealed, because it is easy to react and deliquesce when it meets water. It is recommended to store caustic soda in a cool, dry and well-ventilated place, and avoid contact with water, heat and fire sources. It is suggested that caustic soda should be stored in a sealed barrel, separated from flammable, combustible and acid substances, and mixed storage is prohibited.

1, can dredge

caustic soda can dredge the sewer, but it needs to be dredged with hot water. Mix caustic soda with hot water of 6 degrees evenly, and then pour it into the sewer. The combination of caustic soda and hot water will gradually heat up, so that the grease clothes in the sewer can be dissolved and the sewer can be dredged.

2. White vinegar and soda can be used to dredge the sewer

White vinegar and soda can also be used to dredge the sewer. White vinegar, soda and water are mixed and stirred evenly, and then poured into the sewer. After standing for one night, the clothes in the sewer gradually dissolve and loosen under the action of acid and alkali, and then washed with clear water.

3. Dredge with boiling water

Sewer blockage can also be dredged with boiling water, and the grease in the sewer tunnel will gradually solidify and adhere to the inner wall of the pipeline. The grease in the pipeline can be gradually melted by continuous flushing of the sewer with boiling water, and at the same time, foreign bodies in the sewer will be washed out under the action of water pressure.
