These are real pages from the book. The table of contents is the full one: 7 parts and 68 topics.

It's Not That You Can't Remember. It's That Nobody Put It in Order.

You've read it three times: who owns the pipe from the water main to the stopcock. You close your notes...

...and you no longer know where the water company's pipe ends, where yours begins or how deep it goes. It was just lines of text, one after another.

Supply pipe laid 750–1350 mm deep, owned from the boundary stop valve inwards

Here the supply is one page, drawn as a cutaway: the main in the road, the boundary stop valve, the supply pipe laid 750–1350 mm deep and the stopcock inside the house.

And on the pages next to it every system has its own: the cylinder, the tundish and D2, the S-plan, the trap and the stack.

First you understand why it's done that way. Then the order sticks on its own.

SEE THE DIFFERENCE

Stop memorising rules you can't picture:

THIS
  • Pages and pages of dense text
  • Regulations without a single drawing
  • In the test, you don't know where to start
Water fittings installed in premises supplied by a water undertaker in England and Wales are subject to the Water Supply (Water Fittings) Regulations 1999, whereas the design and installation of sanitation, hot water storage, drainage and the conservation of fuel and power fall within the scope of the Building Regulations 2010, practical guidance on compliance with which is given in Approved Documents G, H and L respectively, to be read in conjunction with the relevant British Standards, including BS EN 806 and BS EN 12056, as applicable.
FOR THIS
  • Every rule drawn
  • One topic per page, with the rules in boxes
  • You remember it because you've seen it
Water Regs, Approved Documents G, H and L, and the British Standards behind them.

What If Every Topic Fit on a Single Page?

Picture this:

Instead of rereading half a page on unvented cylinders without being able to picture one...

...you open the page and find the cylinder drawn with every part labelled: the inlet control group, the expansion vessel, the relief valves and the tundish within 600 mm.

Open-vented vs sealed: 3 bar relief valve, cold fill around 1–1.5 bar

And fluid categories, the S-plan and Y-plan, trap seals, the single stack and the Scotland and NI differences become drawings and tables you can read at a glance.

You stop rereading and start understanding.

That's exactly what Plumbing & Heating Made Visual does. It's not “just another manual”. It's 7 parts and 68 illustrated topics, and at the end 40 practice questions with answers and the numbers to know on two pages.

Because what your brain sees organized, it remembers.

Frequently Asked Questions

How do I receive it?

You get Plumbing & Heating Made Visual as a high-resolution PDF by email, sent to the address you enter when you pay. Read it on your phone, tablet or computer, or print it. The two bonus books, the Fault-Finding Visual Guide and the UK Plumbing Glossary, come by email too.

Is it a monthly payment or a one-off?

A one-off payment of £19.99. No instalments, no subscription.

Who is it for?

For anyone on a Level 2 or Level 3 plumbing and heating course or apprenticeship, for plumbers and mates who want the why behind the rules, and for handymen moving into the trade. It starts from the basics, one topic per page, and goes up to unvented and heating controls. It is based on the rules for England, notes where Wales has its own Approved Documents, and has a full part on what changes in Scotland and Northern Ireland. Check the contents above to see every topic.

What sources is it based on?

The Water Supply (Water Fittings) Regulations 1999, Approved Documents G, H and L Volume 1, BS EN 806, BS EN 12056-2, BS 7593:2019 and HSE HSG274 Part 2. For Scotland, the Scottish Water Byelaws 2014 and the Technical Handbook; for Northern Ireland, the 2009 Water Fittings Regulations and the Technical Booklets.

Is it official course material?

No. It's independent study material, not a course, and it doesn't give you a certificate or a qualification. It isn't produced or endorsed by City & Guilds, EAL, BPEC, WRAS, Gas Safe Register or any awarding body. It follows the regulations and standards those courses are built on, so you can use it alongside whichever course you're on.

Does it replace my course or training?

No. It helps you understand and revise, but it doesn't replace your course, your training on site, the regulations in force or the manufacturer's instructions. It doesn't cover gas work: boilers are covered on the water and controls side, and any gas work must be done by a Gas Safe registered engineer.

Are the practice questions the ones from the exam?

No. The 40 questions are written for this book. They're not official questions from any test or assessment: they're there to help you practise.

Can I print it?

Yes. It's a PDF laid out one topic per page, so you can print the whole book or just the pages you want on site.

What if I don't like it?

You have 30 days. Tell us what didn't work and we'll refund 100%.

One Last Thing Before You Decide...

You don't have to reread the same page hoping this time it sticks.

You don't have to memorise rules you can't picture.

And you certainly don't have to walk into your test without knowing where to start.

One last thing before you decide: the regs won't get any shorter, but they can be easier to picture. 72 pages, one topic per page, two bonus books, PDF by email, and 30 days to tell us if it didn't work.
