Background knowledge: The sewage pipe is the water that discharges urine and urine with a strong odor. The drainage pipe can be discharged directly, and the sewage pipe should be degraded and discharged by the septic tank.
If the drain pipe is connected to the sewage pipe, when the sewage pipe is flushed, the odor in the pipe may be squeezed out of the drain pipe trap through the air flow, causing indoor air pollution. In the same way, if the sewage pipe is connected to the drainage pipe, it will cause pollution of the drainage pipe, causing pollution around the mouth of the drainage pipe. According to the conventional connection method, the sewage pipe is only connected to the squatting toilet, and will not be connected to other pipes.
The drain pipe nozzle has a waterproof treatment, so there will be no problems under normal circumstances.
