Look Inside the Book

Each page has a big drawing and a box with the numbers and steps you need to know:

These are real pages from the book. The table of contents is the full one: 8 parts and 60 topics.

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

You're standing over an open tank with the sampler in your hand, and the buyer's agent asks: "So, does it need pumping?" You have the reading. You're just not sure what it means.

The manual has the answer, but it's spread over three paragraphs about liquid depth, layer ratios and outlet clearance. Read at night after a full day on the job, it doesn't stick.

Measure scum bottom to outlet tee bottom: within 6 in is an EPA pump trigger.

In the book, that question is one page: the tank drawn in cross-section, scum within 6 inches of the outlet tee bottom, sludge within 12 inches, and the total-depth rule in a box, flagged to check against your county. You hold your reading up to the drawing and you know.

The same goes for baffles and tees, float order in a pump tank, the distribution box, drainfield failure signs and recommendation wording: each one has its own page.

You understand it, you make the call and you write it in the report without going back to the manual.

COMPARE FOR YOURSELF

Same Topic, Two Ways to Study It

THIS
  • The manual: line after line after line
  • Sludge measurement explained only in words
  • You show up to the job still unsure
The accumulated sludge layer shall be determined by inserting a sludge-measuring device, such as a clear core sampler or a pole wrapped in light-colored material, vertically through the access opening nearest the outlet structure until resistance at the tank floor is encountered, whereupon the device is closed and withdrawn so that the depth of settled solids may be observed and recorded in inches, with due allowance for the clearance between the top of the sludge layer and the bottom of the outlet tee.
FOR THIS
  • The core sampler in one drawing
  • The inches and the 25% rule in a box
  • You see it and you get it
Lower slowly, close the valve, lift, read the dark layer in inches near the outlet.

One Page, One Topic, All Clear

Think of it this way:

It's a title-transfer inspection. The pump tank lid is off, the alarm never sounded, and you need to know which float does what before you write a word.

You open the book to the float page: three floats drawn in a column, pump off at the bottom, pump on above it, the high-water alarm on top. One look and you know what to test first.

Side by side: a working drainfield and the EPA failure signs, from lawn to house.

Same with measuring sludge, the inlet and outlet tees, the D-box, observation ports and recommendation wording: each one on its own page.

Septic Inspection Illustrated is 8 parts and 60 topics, all drawn, and at the end a review with the key numbers, the most common field and report mistakes, and the terms to know for the exam.

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

Frequently Asked Questions

Is it for me if I've been in the trade for years?

Yes, if you want it all in one order. It doesn't teach plumbing basics: it goes straight to the inspection, what to measure, what to test and how to word it in the report. If you already pump tanks or inspect homes, it puts what you know in inspection order and gives you the key numbers to review before the exam.

Where does the content come from?

From the current NAWT inspection standards and training material, the U.S. EPA Onsite Wastewater Treatment Systems Manual and EPA SepticSmart guidance. The method is the same everywhere; what changes by place (setbacks, pump intervals, title-transfer forms) is flagged on the page so you confirm it with your state and county rules. The review section ends with a state and county checklist to fill in with yours.

Is it official material?

No. It's an independent illustrated study book. It is not published or endorsed by NAWT, the EPA or any county, and it does not give you a certificate, continuing-education hours, NAWT certification or county registration. You still take the official course and exam; this helps you study and review for them.

Does it replace the course or training?

No. It does not replace NAWT training, state or county licensing, OSHA confined-space training or your local onsite rules. It helps you study and review them.

Are the practice questions the ones on the exam?

No. They are written for this book, in exam style, to help you check what you know. They are not official exam questions.

When and how do I get it?

As a PDF by email, sent to the address you enter at checkout. The two bonus books come the same way.

Do I have to pay every month?

No. It's a one-time payment.

Can I have it on paper?

Yes. The PDF is printable, so you can print it at home or at a print shop and keep it 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.

Before You Close This Page

No more rereading the standards with nothing sticking.

Sludge, scum and floats: you see them drawn, and that's it.

You get to the exam and the job knowing where everything is.
