CONSTRUCTION 3911: Essential Pool & Hot Tub Inspection

Pools and hot tubs often require inspection to assess structural, mechanical, electrical and other possible concerns – particularly safety. These detailed reviews are performed by home inspectors who create corrections lists and valuations; health department personnel performing semi-annual inspections; builders appraising potential renovation; and service professionals who are relied upon by their clients to provide timely feedback on existing and potential problems.

This one-day program begins with an in-depth discussion about the DNA of a pool – the essential building blocks, terms and definitions that give the watershape both its geometry and functionality. The foundation in pool-technology included in this class supports more in-depth discussions about standards, codes and laws including ACI 318, National Electrical Code, VGB, ISPSC, the Model Aquatic Health Code and other key references. The program prepares students to pass the Certified Watershape Inspector exam. 

Learning Outcomes

  • Define structural integrity of reinforced concrete, CMU block, fiberglass, vinyl liner, acrylic and steel vessels.
  • Evaluate mechanical, electrical and process piping systems against a checklist covering safety, energy and performance criteria.
  • Identify the differences between residential and commercial projects, and how operations and mechanical configurations vary among installed systems.
  • Define the process of analyzing water chemistry versus standards for healthy water, free of recreational water illnesses.


  • Duration: 8 hours
  • IACET CEUs: 0.8
  • All students who complete the course and evaluation form receive a Certificate of Completion documenting 0.8 IACET CEUs even if they do not continue with the Certified Watershape Inspector (CWI) certification.
