NON-COMPLIANCE WITH PLUMBING CODES IN CHINA: THE CRISIS OF SEWER GAS LEAKAGE
Keywords:
China, Plumbing Code, Sewage, Drains, Sewer Gas, Water Trap, Public HealthAbstract
Sewer gas leakage in China is a pervasive public health issue caused by widespread non-compliance with building codes requiring water traps and proper toilet installation. Despite the existence of national standards, the lack of enforcement and oversight has resulted in hazardous conditions in residential and commercial buildings. This study examines the plumbing deficiencies in the Dinis Hotel in Luoyang and the Anhui Tower Hotel in Beijing following major renovations in 2023. Findings reveal improperly sealed toilets, absence of water traps in drains, and reliance on inadequate air valves, contributing to persistent sewer gas leakage. Sewer gas exposure poses significant health risks, including respiratory illnesses and toxicity from hydrogen sulfide. Addressing this issue requires strict enforcement of building codes, public education on the risks, mandatory training for construction professionals, and adoption of international best practices. Resolving these deficiencies is critical to safeguarding public health and ensuring the effectiveness of China’s construction standards.
