Vent stacks are components of which system?

Heating system
Electrical system
Plumbing system
Cooling system

The correct answer is: Plumbing system

Vent stacks are an integral part of the plumbing system. They serve the crucial function of allowing air to enter the plumbing system, which helps maintain proper pressure within the pipes. By facilitating the airflow, vent stacks prevent vacuum conditions that could impede the flow of wastewater and potentially lead to sewer gas backflow into the building. Additionally, vent stacks allow for the safe discharge of gases produced by the wastewater system into the atmosphere, thereby contributing to both safety and sanitation. The proper functioning of vent stacks is essential for effective drainage and the overall performance of plumbing fixtures in residential and commercial buildings.
