an instructional diagram titled "PLUMBING MEASUREMENTS: SINK." It provides a visual guide for the standard heights of bathroom sink components, measured from the finished floor. VISUAL BREAKDOWN The image features a wall-mounted white ceramic basin against a blue-tiled wall. The plumbing is exposed, showing the water supply lines and the drainage system. 1. VERTICAL HEIGHT MEASUREMENTS The diagram specifies three critical vertical measurements: • Basin Rim Height (85 cm): The top edge of the sin

This diagram represents a residential DWV (Drain-Waste-Vent) system. In plumbing, there are two distinct flows happening simultaneously in these pipes: 1. Gravity (Waste/Water): Flows down to the sewer. 2. Air (Venting): Flows up to the roof to balance pressure and allow the water to move smoothly without gurgling or stopping. 1. The Venting System (The "Lungs") The pipes extending upward are crucial for air circulation. Without them, water would get stuck (like putting your finger over a straw)
