Plumbing Vent Pipe Outside House
A plumbing vent pipe extending outside a house plays a crucial role in preventing sewer gas and odors from escaping into the living space. It allows air to circulate through the drainage system, equalizing pressure and preventing siphoning of water from traps. Typically made of PVC or ABS plastic, the vent pipe runs vertically through the roof or exterior wall, ensuring proper ventilation and preventing sewer gas buildup within the home.
