Study Notes

Plumbing Fixture Traps

The primary function of a plumbing fixture trap is to prevent sewer gases from entering a building through the drainage system.
Trap Seal: The water retained in the trap, preventing gas entry, is known as the trap seal.
Deep Seal P-Trap: This type of trap has a deeper water seal, ranging from 4 to 6 inches, which is beneficial for preventing siphoning and trap seal loss.

### Sanitary Drainage System

Indirect Waste Systems: Serve waste from fixtures not directly connected to the sewer system, like floor drains and sump pumps.
House Sewers: The portion of the drainage system that connects to the main sewer line, starting at the building's sewer connection.

Trap Types and Features

Common Seal P-Trap: Features a water seal depth of 2 inches.
Objectionable Traps: These traps are considered undesirable due to their tendency to lose the water seal, promoting odors and gas entry.
Permissible Traps: Acceptable trap options that meet standard requirements.
Trap Seal Loss: Primarily caused by siphoning, evaporation, and air pressure fluctuations.

Plumbing Ventilation Systems

Ventilation Systems: Essential for creating pressure balance and preventing sewer gas accumulation within the drainage system.
Yoke Vent: A type of vent that connects to a fixture and extends to the outside air, serving as a ventilation pathway.
Wet Vent Structure: This vent allows liquid waste to pass through regularly, acting as both a vent and a waste conduit.
Loop Vent: Primarily used for fixtures located away from partitions, providing a ventilation path for those fixtures.
Individual Vent: A terminal vent for smaller individual or grouped fixture traps.
Circuit Vent: Specifically designed to ventilate two fixture traps discharging into a sanitary cross fitting.
Soil and Waste Vent: Installed to ventilate the soil and waste pipe and its connecting branches, enhancing the overall air flow in the system.
P-Traps: Commonly available in diameters ranging from 1 1/2 to 2 inches.

Plumbing System Components and Design

Cleanout Ferrule: Used for cleaning and inspecting sections of piping and drains.
Sumps: Basins or pits intended for collecting and draining water, commonly used with drainage systems.
Color Coding: Used for identifying pipe types and materials within a plumbing system.
Orange: Indicates plastic pipes used for conveying potable water.
Vertical Opening: A shaft or passage through a building, providing access for various purposes.
Wall/Under-Floor Installation: Refers to the installation of all pipes in plumbing systems within walls and under floors.

### Module and Program Information

Module 03: Covers the fundamentals of the sanitary drainage system.
Course Facilitator: The instructor responsible for guiding students through the sanitary drainage system module.
Commitment: The organization is dedicated to student development and promoting their success.
Vision: The organization aims to create a positive impact in the field of plumbing, guiding students and contributing to industry growth.
Reference for Plumbing Design: The design principles and standards are based on a specific edition of a recognized plumbing reference book.
