PGDB Certifying Plumbing Exam Refresher Course

Video Poster Image

We’re here to make your plumbing exams simpler, faster and way less stressful.

The Trade Lab® plumbing exam refresher course prepares you to sit your PGDB Certifying Plumbing Exam in easy-to-understand modules of easy-to-follow video lessons. We’ve bundled all the info you need into one place, so you don’t have to search through pages and pages of irrelevant content. 

Big benefits of the Trade Lab® course 
 ▂

All PGDB information in one place 

When we Trade Lab® people sat our plumbing certification exams, just sourcing the info we needed took ages. And that was before we could start revising. To save you that kind of pain, we’ve bundled all the content you need into one easy video course. 

Slam-dunk PGDB exam theory 

Like you, we loved our apprenticeship – because it was hands-on, outdoors and practical. But it didn’t prepare us to sit plumbing certification exams. While the apprenticeship is an NZQA qualification, the exams are run by the PGDB – and they test the theory! Our exam refresher course makes the theory clear and easy to follow, so you can slam-dunk it on the day.

Tests, codes, standards and regulations … you’ve got this 

Everyone’s eyes glaze over hearing things like ‘net positive suction pressure’. It’s hard to remember all the different tests, codes, standards and regs. We’ve simplified things, and only include the parts you actually need to know. By the time you’ve done your revision with Trade Lab®, you’ll be all over this stuff.

Feel motivated and confident for the PGDB exams 

You know you’re a good tradie – and good enough to be a certifying plumber. But too many good people sit the exam and fail because they weren’t properly prepared. This is a waste of time and talent, not to mention moneymaking potential. That’s why we started Trade Lab® – to help plumbers like you pass their certification exams, the first time.

Your plumbing’s certificate is the beginning of a rewarding and epic career.

Why Trade Lab®?

 ▂


Learn from the experts

The purpose of the plumbing registration exam is to assess your ability to ’design, specify, and install systems’. That’s what we do on a daily basis – nobody is better qualified to show you what you need to know and do to pass.

We will also help you avoid the three common mistakes most people make preparing for the PGDB exams by themselves: 

Most people don’t give it enough time 

The average successful candidate puts in 200 hours of study to prepare for the exam. It’s worth it.

Most people don’t do a refresher course 

The Trade Lab® refresher course is the best way to get all the info you need at the time you most need it.

Most people don’t get proper guidance 

We not only help you study for the exam, but we also give you tips and tactics for what to do (and not do) during the exam.

The team here at Trade Lab® hold some prestigious positions within the industry, and we actually practise what we preach. We use the same information you’ll be getting on this course ourselves, every day – designing buildings, specifying products, and providing advice to the PGDB.

I recently completed the certifying gasfitter online course. The course is in-depth, focusing on all the necessary parts of the exam, including the detailed process for pipe sizing, clear definitions, and explanations of things I hadn’t even come across yet. All their information is up to date and updated regularly, and they are happy to help with any questions (I had heaps) in the weeks leading up to the exam. I passed with 88 percent. Since then, I have started my own plumbing and gas company. I highly recommend this online course: it’s easily done at home and in your own time."

What's in the certifying plumbing exam refresher course?

 ▂


We will provide you with a structured course to help you pass the PGDB Certifying Plumbing Exam. You can access it wherever you are, whenever you want, on any device. 

Let’s take a look at what you will learn in each of the eight modules.

Module 1 – Overview 

Before we kick into the theory, we will take you through an overview of things such as how to use the website, how to study and sit exams, and how to navigate codes and standards. 

Module 2 – Legislation, Certifiers’ Responsibilities, and Building Integrity 

We'll take you through the different legislation you need to know including the building act and clauses of the NZBC and how they fit together as well as maintaining both structural and fire integrity of a building. 

Module 3 – Sanitary Drainage

In this module we break down each component of a sanitary drainage system and take you through the process of going from a blank piece of paper to a compliant sanitary drainage system for a house (yes - you do get examined on this). 

Module 4 – Sanitary Plumbing

We'll take you through all things sanitary plumbing looking at a range of different aspects that build up a complete and compliant system.

Module 5 – Cold Water Systems and Pipework

We'll take you through the water pipe sizing procedure from start to finish including looking at a few different ways to get to an outcome as well as looking at different ways to supply cold water to a building.

Module 6 – Backflow Prevention and Hot Water Systems

We look at a bunch of different backflow prevention strategies, devices, how they work and the situations they can be used in as well as walking you through a range of different hot water generation systems and how to size them.

Module 7 – Health and Safety

This module covers the Health and Safety at Work Act, WorkSafe NZ and Notifiable Works, and outlines the hazards we face as plumbers and how to manage them safely.

Module 8 – Revision

The all-important revision module! We help you identify areas you need to improve on, how much effort to put into those improvements, and how to move forward quickly and efficiently. We also have great exam tips – what to do on the day and how to maximise your chances of success.

Without the help of Trade Lab®, there is no way I would have achieved the pass marks I did in both my gas and plumbing certifying exams. The way the courses are set out makes them easy to follow and recap if needed. If there are sections you are struggling with, all it takes is an email and help will follow.

If, like me, you were hopeless at school and the thought of more study fills you with dread, then jump on board with Trade Lab® and you'll surprise yourself. I certainly did."
