    Compares sectional, drum, and mini-reel machines by pipe size range and application. Correct machine selection reduces job time and equipment wear.

  • Lesson 4 • Cable and Cutter Head Selection

    Identifies cable gauges and cutter head types matched to blockage material and pipe size. Proper pairing maximises cutting efficiency and protects pipe walls.

  • Lesson 5 • Clearing Techniques by Line Type

    Applies machine operation to kitchen, bathroom, floor drain, and main sewer lines. Technique adjustments by line type improve clearing success rates.

Chapter 5See details

Hydro-Jetting Systems and Techniques

  • Lesson 1 • Safety Protocols for High-Pressure Jetting

    Addresses injection injury risk, PPE requirements, and bystander exclusion zones during jetting. Strict safety adherence prevents severe injuries from high-pressure water streams.

  • Lesson 2 • Jetting Technique and Hose Control

    Teaches hose insertion, pull-back flushing, and controlled advance through the line. Disciplined hose control prevents nozzle loss and ensures complete pipe wall contact.

  • Lesson 3 • Nozzle Selection and Jetting Patterns

    Covers penetrating, flushing, rotating, and root-cutting nozzles and their deployment patterns. Correct nozzle choice determines whether debris is cut, flushed, or emulsified.

  • Lesson 4 • Hydro-Jetting Equipment Overview

    Describes jetter units, hose ratings, nozzle types, and pressure gauges as a system. Understanding component roles enables correct setup and safe operation.

  • Lesson 5 • Pressure and Flow Rate Selection
