Is it the responsibility of the property to clear the blocked kitchen sewer?

The kitchen sewer pipe is blocked and the property has no responsibility to clear it. Because the property is not responsible for the maintenance of living facilities at home, and because most problems in daily life are caused by man, it needs the owner to bear it personally. The property is only responsible for the maintenance and protection of public facilities outside the house, such as elevators, parking spaces, overall greening of the community, park facilities, etc., which belong to the management scope of the property. If there is a problem with the facilities within the above management scope, the property is responsible for maintenance and protection, so it is suggested that the products that need maintenance should first be clear whether they are at home or outside.
