Plumbing and Sanitary Design Course

Lesson 1 • Water Supply System Basics

Introduces cold and hot water distribution from the main supply to fixtures. Provides the supply-side foundation for later design chapters.

Lesson 2 • Pipes, Fittings, and Materials

Examines pipe materials, fittings, and their selection criteria. Connects material properties to system performance and durability.

Lesson 3 • Drainage and Venting Principles

Explains gravity drainage, trap functions, and vent stack roles. Prepares students for detailed drain-waste-vent system design in later chapters.

Lesson 4 • Regulatory Framework Overview

Surveys the types of codes, standards, and inspection processes governing plumbing. Establishes compliance awareness applied in every subsequent chapter.

Lesson 1 • Pipe Sizing for Sanitary Systems

Applies fixture unit totals to select correct pipe diameters for drains and vents. Ensures adequate flow capacity without oversizing.

Lesson 2 • Fixture Units and Load Calculations

Introduces drainage fixture unit values and their use in sizing pipes. Accurate load calculations are the basis for all sanitary pipe sizing.

Lesson 3 • Drain-Waste-Vent System Architecture

Details the hierarchy of drains, waste lines, and vent stacks in a complete DWV system. Builds on drainage basics to introduce full system topology.

Lesson 4 • Sanitary Layout Drawing Techniques

Translates system logic into plan-view and isometric sanitary drawings. Produces clear construction documents used by installers and inspectors.

Lesson 1 • Pressure and Flow Fundamentals

Establishes hydraulic concepts including static pressure, velocity, and friction loss. These principles underpin every supply sizing decision in the chapter.

Lesson 2 • Cold Water Distribution Design

Applies pressure and demand data to size cold water mains, branches, and risers. Produces a balanced distribution network for multi-story buildings.

Lesson 3 • Hot Water System Design

Covers geyser selection, recirculation loops, and hot water pipe sizing. Ensures adequate temperature and flow at all hot water outlets.

Lesson 4 • Water Supply Fixture Units

Introduces supply fixture unit values and probability-based demand estimation. Links fixture demand to pipe sizing using standard flow tables.

Lesson 5 • Backflow Prevention and Cross-Connection

Identifies cross-connection hazards and selects appropriate backflow prevention devices. Protects potable water quality as required by health standards.

Lesson 1 • Site Stormwater Management

Addresses surface grading, catch basins, and underground conveyance for site runoff. Integrates roof drainage discharge into the site stormwater network.

Lesson 2 • Sizing Roof Drainage Systems

Applies rainfall and area data to calculate required gutter and leader sizes. Ensures drainage capacity meets design storm without ponding.

Lesson 3 • Rainfall Intensity and Runoff Concepts

Introduces rainfall intensity data, return periods, and runoff coefficients. Provides the hydrological inputs required for all stormwater sizing.

Lesson 4 • Stormwater Drawing and Documentation

Produces site drainage plans, profiles, and detail sheets for permit submission. Reinforces documentation standards established in earlier chapters.

Lesson 1 • Pressure Zoning Strategies

Explains how building height creates excessive static pressure and how zones solve it. Establishes the zoning logic applied throughout the chapter.

Lesson 2 • Mechanical Room and Riser Coordination

Integrates plumbing risers with mechanical, electrical, and structural systems in shafts. Produces coordinated riser diagrams that avoid conflicts.

Lesson 3 • Water Meter and Submetering Systems

Covers master meter sizing, tenant submetering, and data logging for large buildings. Supports billing accuracy and water conservation management.

Lesson 4 • Booster Pump System Design

Covers pump selection, variable-speed drives, and pressure tank sizing for high-rise supply. Ensures consistent pressure at all floors under varying demand.

Lesson 1 • Industrial Process Plumbing

Introduces process water supply, chemical-resistant drainage, and neutralization pits. Adapts standard plumbing design to industrial process requirements.

Lesson 2 • Healthcare Facility Plumbing

Covers medical gas rough-in, infection-control fixtures, and Legionella prevention in hospitals. Applies strict hygiene standards to supply and drainage design.

Lesson 3 • Food Service and Commercial Kitchen Plumbing

Addresses grease interceptors, pre-rinse stations, and indirect waste connections for kitchens. Ensures compliance with food hygiene and drainage standards.

Lesson 4 • Swimming Pool and Spa Plumbing

Covers recirculation, filtration, and chemical dosing piping for aquatic facilities. Applies hydraulic sizing to closed-loop pool systems.

Lesson 1 • Water Consumption Benchmarking

Establishes baseline water use by building type and occupancy to identify reduction targets. Provides the measurement foundation for all conservation strategies.

Lesson 2 • Low-Flow Fixture Selection

Compares flow rates of WCs, taps, and showerheads against efficiency thresholds. Demonstrates how fixture selection directly reduces potable water demand.

Lesson 3 • Rainwater Harvesting Systems

Designs collection, storage, and distribution systems for harvested rainwater in non-potable applications. Integrates with roof drainage systems from earlier chapters.

Lesson 4 • Green Building Rating Integration

Maps water efficiency measures to green building rating system credit categories. Enables designers to document and certify water performance outcomes.

Lesson 1 • Plumbing Specifications Writing

Covers specification sections for materials, installation, and testing requirements. Ensures drawings and specifications form a complete, non-contradictory contract set.

Lesson 2 • Interdisciplinary Coordination

Addresses clash detection, coordination meetings, and drawing overlay with other trades. Prevents field conflicts that cause costly rework during construction.

Lesson 3 • Construction Administration for Plumbing

Covers shop drawing review, site observation, and punch list management during construction. Ensures installed systems match design intent and specification requirements.

Lesson 4 • Complete Drawing Set Organisation

Defines the sheet types, numbering conventions, and content standards for a full plumbing set. Establishes document organisation applied to all deliverables.
