These are real pages from the book. The table of contents is the full one: 8 parts and 59 topics.

The Problem Isn't You. It's How It Was Explained to You.

You're standing in a mechanical room: a boiler fill line, a hose bibb with the hose dropped in a bucket, a chemical feed tank. The written exam asks which ones are cross-connections, and which are direct or indirect.

The manual gives you the definition in three long paragraphs: actual or potential connection, potable system, any source of pollution or contamination. The words are right, but you can't see the room in them.

Hose, irrigation, boiler, chemical tank, fire line: 5 cross-connections, each labeled direct or indirect

In this book, that same topic is one page: hose, irrigation, boiler, chemical tank and fire line, each one drawn and labeled direct or indirect. You see exactly where the drinking water meets something it shouldn't.

The rest of the book works the same way. Backsiphonage, backpressure, degree of hazard, the RP drawn open, the differential gauge: each one has its own page.

So when you walk into that room, on the job or on the exam, you spot the cross-connections and know what protects each one, without going back to the manual.

COMPARE FOR YOURSELF

Same Topic, Two Ways to Study It

THIS
  • The manual: line after line of text
  • Pressure and hydraulics explained only with words
  • You walk into the exam still unsure
Pressure is defined as the force exerted per unit of area and is commonly expressed in pounds per square inch (psi). The relationship may be stated as P = F ÷ A, where P represents pressure, F represents the total force in pounds and A represents the area in square inches over which said force is applied. Accordingly, a force of 100 pounds distributed uniformly across an area of 2 square inches results in a pressure of 50 pounds per square inch.
FOR THIS
  • Pressure drawn as weight on one square inch
  • The formula and the worked numbers in a box
  • You see it and you get it
Pressure = force ÷ area: 100 lb on 2 in² = 50 psi.

One Page, One Topic, All Clear

Think of it this way:

You're at the hands-on exam. The DC is in front of you, the kit is hooked up, and the evaluator says: show me check valve #1.

In the book, you open the DC test pages and see the frames: which valve you open, which you close and where the needle has to go, with the gauge drawn at every step.

Differential gauge: high minus low, in psid; equal pressures read zero.

Same with the PVB air inlet, the RP relief valve opening point, feet of head and psi, containment vs isolation and the RP installation rules: each one on its own page.

Backflow Tester Exam Illustrated is 8 parts and 59 topics, all drawn, and it ends with an exam-day review: every assembly, every test sequence and the hydraulics formulas, one page each.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if I've been a plumber for years and haven't taken an exam in decades?

Yes. It doesn't explain what a valve is. It starts from the exam: hydraulics, hazard, the four assemblies and the field tests, drawn so you can review fast.

Where does the content come from?

From ASSE/IAPMO/ANSI Standard 5110 on tester qualifications, the U.S. EPA Cross-Connection Control Manual and the published field test procedures state programs use: the USC Manual, ABPA and AWWA M14. Every reading and minimum in the book is checked against those sources.

Is it official, and does it match my state's procedure?

No, it's an independent illustrated study guide. The test pages follow the logic shared by the main U.S. procedures (USC, ABPA, AWWA M14), and every procedure page reminds you to check the one your state, program or water purveyor requires.

Does it replace the tester course?

No. It doesn't give you a certificate or continuing education hours. Your certification still requires the approved course and the exams your program sets. This book helps you review and understand what you see there.

Are the practice questions the real exam questions?

No. They're written for this book, in exam style, with each answer explained. They aren't official questions from any exam.

When and how do I get it?

The book and the 2 bonus books arrive as PDFs by email, at the address you enter at checkout.

Do I have to pay every month?

No. It's a one-time payment.

Can I have it on paper?

Yes. It's a printable PDF: print the whole book or just the pages you want to keep in the truck.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.
