There is a lot of green cotton in the sewer. What if I can't get into the water quickly?

There are U-shaped water pipes under these basins to prevent the odor of sewers from entering the house, but there is also a disadvantage.

It is easy to accumulate oily garbage and block water pipes, and it should be cleaned at least once a year. This U-shaped deodorizing tube is detachable and can be removed by hand without tools. After cleaning, install it as it is. Generally, hair, sludge, vegetable residue and the like will be cleaned inside.
