How many types of plumbing systems are commonly recognized?

Plumbing systems are commonly recognized in three main types: potable water systems, drainage systems, and vent systems.

Potable water systems are designed to deliver clean water for drinking and sanitation. This involves the use of piped networks that bring fresh water from treatment facilities to homes and buildings.

Drainage systems, on the other hand, are responsible for removing wastewater from these buildings. They capture and transport greywater (from sinks, showers, etc.) and blackwater (from toilets) away from the property, ensuring proper disposal and sanitation.

Vent systems are essential for maintaining proper air pressure in the drainage system and preventing the buildup of harmful gases. They allow sewer gases to escape while ensuring that wastewater flows smoothly through the plumbing pipes.

Recognizing these three distinct types of plumbing systems is fundamental for understanding how plumbing works, as each type plays a critical role in the overall function and efficiency of a building’s plumbing infrastructure.
