The H-pipe plays an important role in the drainage system, as it not only connects various branch pipes but also provides direction and regulation of water flow.
The dual-stack drainage system consists of two pipes: one for drainage and one specifically for ventilation (also known as the vent stack). The drain stack and vent stack are connected via an"H-pipe."Through the function of the vent stack and H-pipe, the drain stack maintains a steady air-water mixed flow, preventing any positive or negative pressure differentials within the drain stack. This ensures there are no water seal failures or sewage overflow issues.
