Secondary drainage does not belong to public equipment, but belongs to indoor equipment. Therefore, when the secondary drainage is blocked, you can't find a property company to help repair it, and you can't apply for a house maintenance fund to repair it. I have to pay for it myself.

You can pour an appropriate amount of pipe dredging agent into the secondary drainage, wait for a while, and then pour a lot of hot water to dredge the secondary drainage. You can also pour an appropriate amount of baking soda into the secondary drainage, then pour an appropriate amount of boiling water, wait for about half an hour, and finally pour a lot of clear water to dredge the secondary drainage.
