Why shouldn‘t we place washing machine or water skip on the balcony?

    Answer: Balcony floor drain is used to drain rainwater, which will be drained into the neighborhood rain water pipeline through the outer vertical pipe, a pipe used to collect rainwater on the roof and balcony. If washing machine and water skip are placed on the balcony, the sewage generated will flow into the vertical pipeline and then into neighborhood rain water pipeline, causing a mixed drainage of rainwater and sewage especially in the separate drainage system. The sewage flowed into the rainwater pipelines will afterwards flow into the watercourse, turning it into stinky black river and causing pollution to the water environment.
