What if the kitchen sewer is not underwater?

1, go to the market to buy a pipe dredger, bend the tail into a hook shape, put the dredger into the drain while draining, stir constantly after the end, take out the garbage, and repeat it several times.

2. Mix detergent or washing powder into boiling water, then pour it into the drain and soak for a while. If the blockage problem still cannot be solved, you can pour a cup of vinegar.
