Abstract:
The construction of national water-saving city and the implementation of water efficiency label increase the popularity rate of water-saving sanitary appliances, and further decrease the water consumption of sanitary appliances. However, the reduction of water consumption may lead to problems such as pipeline blockage and secondary flushing. This paper constructed a full-scale test system consisting of five water-saving toilets with water efficiency grade of 1 and a horizontal drainage pipe with length of 12 m in a public toilet, and simulated the effects of scenarios such as the continuous use of the toilet seat (or not), the occupancy ratio of the toilet and the slope of the horizontal drainage pipe on the conveying performance of the plastic horizontal drainage pipe. The slope of the horizontal drainage pipes in public toilets should not be less than 0.012 in order to ensure the conveying performance of DN110 and PVC-U plastic horizontal pipes.
