There were the following reasons why the floor drain would turn back if it was blocked. First, the diameter of the sewer pipe was too small to meet the drainage needs, and water would come out from the floor drain. Secondly, if the sewer pipe was blocked, it would cause poor drainage, especially when the water from the floor drain had dirt and an unpleasant smell. This blockage was more obvious. Third, when the washbasin and the floor drain shared a pipe, the water pipe could not withstand the water flow, and the water would overflow from the floor drain. In addition, if there was construction waste blocking the sewer pipe, or if the owner and the property were negligent in maintenance during the use, if there were large objects and non-decomposing sundries thrown into the sewer, or if the kitchen food residue oil was directly poured into the sewer, it would cause the sewer pipe to be blocked and lead to the floor drain. Especially in old houses, the sewer pipe had been used for a long time. The dirt and impurities stuck to the inner wall of the pipe, making the pipe diameter smaller, and it was easy to cause water to flow back. Also, during the renovation of second-hand houses, if the design and construction of the drainage pipe had problems such as the diameter of the pipe being thin, the bottom horizontal pipe being too long, the angle of the bend being too sharp, and the slope being insufficient, resulting in insufficient drainage capacity, or the construction waste being directly discharged into the sewer pipe during the construction and renovation stage, causing blockage, it would cause the floor drain to reverse.
