PGDB Certifying Drainlaying Exam Refresher Course
We’re here to make your drainlaying exams simpler, faster and way less stressful.
The Trade Lab® drainlaying exam refresher course prepares you to sit your PGDB Certifying Drainlaying 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 drainlaying 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 drainlaying 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 drainlayer. 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 drainlayers like you pass their certification exams, the first time.
Why get your drainlayer’s certificate?
When you get your drainlayer’s ticket, the sky’s the limit, and great things can happen.
· Become a certifying drainlayer
· Work on bigger projects
· Have more independence
· Start your own business
· Earn more money
· Take on your own apprentices
After passing his certifying and tradesman exams, Trade Lab® founder Nik McIntosh did a Bachelor of Construction, then landed a job at BECA running the largest hydraulic engineering team in New Zealand. He is also leaned on to provide advice on industry matters and opinions by the Plumbers, Gasfitters and Drainlayers Board (PGDB).
Your drainlayer’s certificate is the beginning of a rewarding and epic career.
Why Trade Lab®?
Learn from the experts
The purpose of the drainlaying 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 was put on to Trade Lab® by a friend. We shared the same problems: neither of us had sat an exam in years; we needed to study and refresh before the certifying drainage exam; and we were both busy at work and at home with young families. Being able to log in and cover a couple of topics each night made study very easy. I found the delivery suited me as it limited the amount of reading I needed to do after a busy day. It wasn’t until I sat the exam (and passed convincingly) that I realised just how relevant the study material had been. I recalled many of the questions being covered throughout the Trade Lab® course.
I would recommend these courses to all new and old preparing for an exam or as a very easy way to refresh your trade theory."

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

Module 4 – Drainage Components
We take you through all things drainage, looking at the range of different components that build up a complete and compliant system.

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.
I would recommend Trade Lab® to anyone serious about passing their PGDB exams. Everything you need to know is included in the course content. And the ability to go over the modules as many times as needed is extremely helpful. Combine this with practising on past exam papers and you’ll be set for the big day."
