Sanitary systems

The residential plumbing system is often taken for granted, but it is an important part of the structure.
A complete plumbing system provides an adequate supply of water and removes waste.
There are three principal parts:

1. Water supply system.
2. Water and waste removal system.
3. Plumbing fixtures.

The Plumbing Plan is a plan view that shows the complete plumbing system. The plumbing plan shows the location, size, and type of all plumbing equipment.
The plumbing plan should include:

• Waste lines and vent stacks.
• Drain and plumbing fixture locations.
• Size and type of pipe to be used.
• A plumbing fixture schedule.
• Symbols Legend.
• General notes.
• A plumbing plan is required for each floor of the house.
