illustrates a diagram of a residential Sanitary Installation (plumbing drainage system) for a single bathroom showing how the drain lines from the sink toilet and shower connect to the main waste pipe using gravity flow.

🚽 COMPONENTS AND DRAINAGE FLOW
The entire system is designed as a Drain-Waste (DW) network that relies on gravity to carry wastewater away from the fixtures. The pipe material is identified as PVC (Polyvinyl Chloride) a common material for modern drainage systems.

1. SINK (LAVATORY) DRAINAGE
* P-Trap: The sink utilizes a P-Trap (the U-shaped bend under the sink) which is essential. The trap holds a plug of water to create a seal preventing sewer gases from rising into the bathroom.
* Drain Pipe Size: The drain pipe coming from the sink is labeled as 1.5" (1-1/2 inches) which is the standard minimum size for a lavatory drain.
* Connection: This smaller drain connects to a larger horizontal pipe sometimes called a branch drain which eventually flows into the main soil stack.

2. TOILET (WATER CLOSET) DRAINAGE
* Drain Pipe Size: The toilet connects directly to a larger pipe labeled as 4-inc PVC (4-inch PVC). This size is required to handle the volume and solids of toilet waste (black water) without clogging.
* Trap: The toilet bowl itself contains an integrated trap (S-trap) so no external P-trap is needed on the drain line.

3. SHOWER DRAINAGE
* Shower Drain: The pipe connects the shower pan drain to the main horizontal line. It typically includes a P-trap (not fully detailed but implied) beneath the floor to prevent sewer gases from entering.
* Connection: The shower drain connects to the main line combining with the toilet waste.
💧 MAIN WASTE LINES
* 4-inc PVC: This large horizontal line primarily serves as the main drain for the toilet and the shower. This is often referred to as the soil line when carrying human waste.
* 3-inc PVC: This is indicated as the final diameter of the main drain line leaving the room or connecting to the main building stack. While 4" is common for the toilet the pipe may reduce to 3" if codes permit or the 3" pipe may represent the common branch drain diameter. The difference in size (3-inch and 4-inch) is crucial to ensure proper flow and prevent clogs.
Missing Component: A critical element not explicitly shown in this simplified DWV diagram is the Vent System. Without a vent pipe connecting to the system (usually extending up to the roof) the draining water would create a vacuum which could suck the water out of the P-traps allowing sewer gases to enter the home. The label "Drain" on the 1.5" line typically implies a connection point for a vent.
