The main pipe of the building is blocked. Who should I call to clean it up?

The residential property is responsible for clearing and maintaining the horizontal burial in the residential area, and is responsible for connecting the unit risers. Generally, the supervisor can dredge outdoors, but the dredging of unit riser needs to enter different floors for indoor operation. However, if the facilities of * * * are damaged, for example, the sewer standpipe of the public * * * is blocked, because it is part of the public and belongs to the owner * * *, so the maintenance responsibility lies with the owner. Maintenance costs (if any) should also be shared by the owner.

The residents on the second floor came to look for it, because the water came into the house from her kitchen. At that time, I followed her to knock on the door and contacted the residents from the third floor to the seventh floor (the top floor) of her house, and everyone collectively paid the water bill. The cost of water supply and drainage is 150. For each 25 yuan, I prefer water supply and drainage risers (including exhaust risers and rainwater risers) and flat pipes connected with them at the bottom, which should belong to public facilities and the maintenance scope of property management companies. If the owner needs it, the property engineer can help or charge for dredging with dredging equipment. Owners can also hire professional dredging personnel in the society to pay for dredging. The property management company won't care if there is anything broken in your home. They are only responsible for public areas. However, there is a charge for your property.

If the main road is blocked and you pay the property management fee, the property will be responsible for handling it. If it's not the main road, your house is blocked, and you are responsible. Many cases of water plugging in the kitchen are because the property in the sump has not been cleaned for a long time, and solid garbage has blocked the nozzle of the room leading to the horizontal pipeline. In the later stage, the nozzle of the drainage pipe redone by oneself is generally higher and not easy to block. If it is used by the owner, for example, sewage from other homes also flows through your pipeline, it belongs to the used part and should be dredged by the property. Need large-scale maintenance, the cost paid from the special maintenance funds. In fact, the property management is not afraid of dredging, and it is afraid that the owner's home will be flooded and cause loss compensation. It's really hard to be reasonable and unreasonable. I think it should be reasonable to charge the sewage pipe after the property is cleared.
