Tips for dredging sewers:

1. Now there is a special waterway dredging agent on the market, which is especially effective for dredging blocked water pipelines. It is often used in some restaurants and hotels. When in use, clean up the accumulated water in the sanitary ware first, and pour a proper amount of waterway dredging agent into the blocked sewer pipe. If there is no water in the pipe, then pour half a cup of clean water into it, wait for about 21 minutes, and then flush it with a large amount of water.

2. If the sewer is blocked due to the accumulation of hair, you can buy a hand-operated spiral steel wire in the market, push it down from the mouth of the floor drain, shake the spiral steel wire when it touches a foreign object, and slowly pull it up, so that foreign objects such as hair blocked in the pipeline will be brought out by the spiral steel wire.
