What to do if the bungalow is low and the sewer backs up

Firstly, caustic soda or pipeline dredging agent can be used to dredge the pipeline, and secondly, the pipeline dredging device can be used to clean up the impurities and garbage in the pipeline; Finally, a high-pressure water cannon can be used to clean up the oil from the pipes.

How to Prevent Sewer Blockage:

In life, we must develop a good habit of use, it is best not to throw all the garbage into the waterway, for example, you can clean up the bones, fish bones and other residues into the trash can first.

Then use a paper towel to wipe the grease in the tray and wash it with warm water, so as to prevent the grease from flowing into the sewer and clinging to the pipe, which can cause the sewer to be blocked.

For the sewer in the bathroom, special attention should be paid to the flow of hair into the sewer when washing hair and bathing, and the hair on the floor drain should be cleaned up in time, otherwise it is easy to form a blockage network and cause blockage.

When using water in the kitchen or bathroom, you can use a container to fill it up, and when it is finished, put the water in one go, which will form a force that can wash away the dirt on the sewer pipe wall.

If you use it in winter, you can pour boiling water into the water pipe regularly, which can effectively flush off the oil attached to the water pipe wall, but if the sewer pipe at home is relatively thin, be careful not to use too high temperature boiling water, otherwise it is easy to cause sewer deformation.

Generally speaking, there are three reasons.

1. The hydraulic conditions are not good, the residential drainage is generally gravity self-flowing drainage, and the sewage is discharged into the drainage riser by the sanitary appliances of the residence, and then discharged into the drainage horizontal trunk pipe. Finally, it is discharged into the outdoor drainage inspection well.

Generally, the drainage speed of the drainage riser is greater than that of the drainage horizontal trunk pipe, and when the sewage is discharged to the bottom of the drainage riser and transferred to the drainage horizontal trunk pipe, instantaneous congestion will be generated, and a positive pressure water column for a short period of time is formed at the bottom of the drainage riser, if the hydraulic conditions are not good, such as the drainage riser and the drainage horizontal trunk pipe are not connected with two 45. When the elbow is rotated, the diameter of the drainage horizontal trunk pipe is small, the slope is small, or when the blockage occurs, the positive pressure water column is relatively high, and when the positive pressure water column is higher than the sanitary appliances of the ground floor residence, the sewage overflows from the sanitary appliances of the ground floor house, which is commonly known as the sewer backwater.

2. Pipe problem, in the past, the drainage pipe of the residence was generally sand mold cast iron pipe.

The inner wall is rough, easy to hang dirt, and it is easy to rust if the anti-corrosion is not done well, resulting in poor drainage. The inner wall of the plastic drainage pipe and the mechanism centrifugal cast iron pipe is smooth, and the dirt is not easy to hang up and cause blockage, and the water passing capacity is 10% 26% larger than that of the sand mold drainage cast iron pipe. Local construction committees have explicitly prohibited the use of sand mold drainage cast iron pipes in new residential projects, and promoted the use of plastic drainage pipes and mechanism centrifugal cast iron pipes.

3. The settlement of the house is large, and the slope of the drainage trunk pipe during residential construction generally meets the standard slope, and the flow rate of sewage in the pipeline can reach the self-purification flow rate. It is normal for the house to settle due to its own weight and unreal foundation when it is first built, but it is not attached great importance to the design and construction, and corresponding measures are taken, resulting in a large amount of house settlement, and the drainage outlet pipe is pressed, resulting in the reduction of the slope of the drainage outlet pipe, or even the reverse slope, and the drainage outlet pipe will be crushed when it is serious, resulting in poor drainage.
