Pool Maintenance Course

Lesson 1 • Pool Types and Configurations

Covers in-ground, above-ground, and commercial pool designs and their structural differences. Provides context for maintenance decisions made throughout the course.

Lesson 2 • Plumbing and Valves

Covers pipe materials, valve types, and plumbing layout conventions used in pool systems. Accurate valve identification prevents errors during equipment servicing.

Lesson 3 • Heating and Energy Systems

Introduces gas, heat pump, and solar heating options and their integration with pool plumbing. Sets the stage for energy-efficient maintenance strategies.

Lesson 4 • Filtration System Components

Identifies sand, cartridge, and diatomaceous earth filters and their operating principles. Connects component knowledge to cleaning procedures covered in Chapter 3.

Lesson 1 • Cyanuric Acid and Stabilization

Explains cyanuric acid's role in protecting chlorine from UV degradation and its dosing limits. Overstabilization is a common field problem addressed in Chapter 4.

Lesson 2 • Calcium Hardness and Saturation

Covers calcium hardness targets and the Langelier Saturation Index for corrosion and scale prevention. Connects to equipment longevity discussed in Chapter 5.

Lesson 3 • Sanitizers and Disinfection

Explains chlorine, bromine, and alternative sanitizers and how they eliminate pathogens. Sanitizer selection directly affects dosing and safety protocols.

Lesson 4 • pH and Total Alkalinity

Defines pH scale relevance and total alkalinity as a pH buffer. These two parameters are the starting point for every chemical balancing procedure.

Lesson 1 • Test Kit Types and Selection

Compares drop-based, test strip, and photometric test kits by accuracy and application. Choosing the right kit prevents misdiagnosis of water chemistry problems.

Lesson 2 • Interpreting and Recording Results

Teaches result interpretation against target ranges and proper log documentation. Accurate records support trend analysis and regulatory compliance.

Lesson 3 • Sampling Technique and Frequency

Establishes correct water sampling locations, depths, and testing schedules. Consistent sampling technique ensures results are representative and repeatable.

Lesson 4 • Testing Core Parameters

Walks through step-by-step procedures for testing pH, chlorine, alkalinity, and calcium hardness. Accurate parameter readings are the foundation of every chemical adjustment.

Lesson 1 • Chlorination and Shock Treatment

Details routine chlorination dosing and breakpoint chlorination for combined chlorine elimination. Shock treatment is the most frequently performed corrective procedure in pool maintenance.

Lesson 2 • Dosing Calculation Principles

Introduces volume-based dosing formulas for raising and lowering each parameter. Accurate calculation prevents overdosing, which is a leading cause of equipment damage.

Lesson 3 • Calcium and Stabilizer Adjustments

Explains calcium chloride addition and dilution strategies for stabilizer reduction. Connects to saturation index management introduced in Chapter 2.

Lesson 4 • Algaecides and Specialty Chemicals

Covers preventive and curative algaecide use alongside clarifiers, enzymes, and metal sequestrants. Specialty chemicals complement but do not replace proper sanitizer levels.

Lesson 1 • Automation and Control Systems

Introduces timers, variable-speed pump controllers, and automated chemical dosing systems. Automation reduces labor and improves chemical consistency in managed pools.

Lesson 2 • Filter Cleaning and Backwashing

Details backwash procedures for sand filters, cartridge cleaning, and DE filter recharging. Proper filter maintenance directly controls water clarity and flow rate.

Lesson 3 • Pump and Motor Servicing

Covers impeller inspection, seal replacement, and motor lubrication procedures. Pump failures are the most common equipment breakdown in pool systems.

Lesson 4 • Electrical Safety and Bonding

Covers equipotential bonding requirements, GFCI protection, and safe electrical inspection practices. Electrical hazards in pool environments can be fatal if overlooked.

Lesson 1 • Tile and Waterline Cleaning

Covers calcium scale removal, scum line treatment, and tile cleaning product selection. Waterline buildup is both unsightly and a sign of chemical imbalance.

Lesson 2 • Vacuuming Techniques

Details manual vacuum assembly, vacuuming patterns, and automatic cleaner operation. Thorough vacuuming removes settled debris that brushing dislodges from surfaces.

Lesson 3 • Brushing Pool Surfaces

Explains brushing patterns for plaster, vinyl, and fiberglass surfaces to prevent algae adhesion. Correct brush selection avoids surface damage while maximizing cleaning effectiveness.

Lesson 4 • Skimming and Debris Removal

Covers surface skimming technique, basket emptying, and debris management priorities. Removing surface debris before vacuuming prevents filter overload.

Lesson 1 • Water Clarity Problems

Diagnoses cloudy, green, and foamy water conditions and their chemical or mechanical causes. Clarity problems are the most visible indicator of maintenance failure.

Lesson 2 • Algae Identification and Treatment

Distinguishes green, yellow, and black algae by appearance and treatment requirements. Correct identification determines the shock dose and brushing intensity needed.

Lesson 3 • Recurring Problem Root Cause Analysis

Teaches structured root cause analysis for problems that return after initial treatment. Addressing root causes rather than symptoms reduces callback frequency and client complaints.

Lesson 4 • Equipment Malfunction Diagnosis

Covers loss of prime, low flow, heater lockout, and filter pressure anomalies. Systematic equipment diagnosis reduces unnecessary part replacement and service time.

Lesson 1 • High-Use and Event Preparation

Addresses pre-event chemical loading, increased filtration run times, and post-event recovery. High bather loads rapidly deplete sanitizer and require proactive chemical management.

Lesson 2 • Spring Opening Procedures

Covers cover removal, equipment reinstallation, initial chemical balancing, and system startup. A thorough opening prevents early-season algae blooms and equipment failures.

Lesson 3 • Year-Round Preventive Maintenance Schedule

Builds weekly, monthly, and annual maintenance task calendars for residential and commercial pools. Scheduled maintenance reduces reactive service calls and extends equipment life.

Lesson 4 • Winterization and Pool Closing

Details chemical winterization, water level adjustment, equipment blowout, and cover installation. Proper closing prevents freeze damage and simplifies the following spring opening.
