Regular plumbing pipes can be utilized for which of the following purposes?

Regular plumbing pipes are designed to serve multiple functions within a plumbing system, particularly in facilitating the flow of water and waste. They are critical components that allow for proper drainage and waste management within a structure.

The use of plumbing pipes for both vents and drains is essential for ensuring that wastewater is efficiently removed and that air can move freely within the pipes. This dual functionality helps to prevent the buildup of pressure that could lead to clogs and enhances overall system efficiency. Vent pipes specifically allow air to enter the plumbing system, which is necessary for the drainage system to function properly by balancing pressure.

By recognizing that plumbing pipes can effectively handle both drainage and ventilation roles, it is evident why this answer is appropriate. The design and materials of regular plumbing pipes accommodate both types of functions, contributing to their versatility in residential and commercial plumbing applications.
