Look Inside the Book

Every page has a large drawing and a box with the numbers and steps you need to know:

The pitless adapter exits below the frost line; the drop pipe hangs from its O-ring-sealed slide.

These are real pages from the book. The table of contents is the full one: 9 parts and 62 topics.

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

You're looking at an exam question: 125 feet to the pumping level, 60 psi at cut-out, 10 gpm through the drop pipe. Find the total dynamic head.

You've done this on real jobs. But the manual explains it in paragraphs: lift, then pressure head, then a friction table three pages later. By the time you get to the answer, you've lost the order.

125 ft + 138.6 ft + 12 ft = 275.6 ft TDH at 10 gpm

In the book, that same example is one drawing: the well, the pipe and the tank, with each piece of head stacked beside it. 125 ft of lift + 138.6 ft of pressure head (60 psi × 2.31) + 12 ft of friction from the table = 275.6 ft at 10 gpm, added in the same order every time.

And it's not just TDH. Precharge, the pitless adapter, the submersible pump bottom to top, 3-wire motor ohms and troubleshooting from the outside in: each one has its own page.

So when the question shows up with numbers, you picture the drawing, follow the steps and work it out without going back to the manual.

Same Topic, Two Ways to Study It

THIS
  • The manual: line after line of text
  • Pump parts explained only in words
  • You show up to the exam still unsure
The submersible pump assembly consists of a sealed electric motor coupled to a multistage centrifugal pump end. The motor, positioned at the lowest point of the assembly, is protected by a shaft seal that prevents the entry of well water into the motor cavity. Above the seal, water enters through the intake screen and is progressively pressurized by a series of impeller and diffuser stages, the number of which determines the developed head, before passing through the integral check valve and the discharge connection to the drop pipe.
FOR THIS
  • The submersible pump in one drawing
  • The parts, bottom to top, in a box
  • You see it and it clicks

One Page, One Topic, All Clear

Think of it this way:

A customer calls: the pump kicks on every 20 seconds. You're at the tank with a tire gauge and you need the precharge number right now.

You open the book to the precharge page and see the tank drawn with its air side and its water side: cut-in minus 2 psi. A 40/60 switch gets 38 psi, a 30/50 gets 28.

Panel → pressure switch → control box → amps → ohms and megohms. Pull the pump last.

Same with the pitless adapter, TDH, the control box, 3-wire motor ohms and the megohm test: each one on its own page, drawn.

Well Pump Installer Illustrated is 9 parts and 62 topics, all drawn, and at the end the 10 numbers to have on hand, the formulas on one page and two field checklists.

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

Frequently Asked Questions

Is it for me if I've been setting pumps for years?

Yes. It isn't a beginner's book: it puts what you already do in the field in one order, and adds the calculations and code points the exam asks with numbers. It also works for helpers and for plumbers or electricians taking on well work.

Where does the content come from?

It's checked against the NGWA pump installer exam content areas, the 2023 NEC (Articles 250 and 430), state well construction codes, EPA private well guidance and pump and motor manufacturers' installation data. Your state may have adopted an earlier NEC edition and has its own well rules, so every code point is marked for you to confirm against your state's current version. If your state gives its own pump installer exam, the system, the calculations and the troubleshooting order are the same.

Is this official material?

No. It's an independent study book. It isn't published, approved or endorsed by NGWA, NFPA or any state agency, and buying it doesn't give you a certificate, a license or continuing education hours. You still take the exam through your certifying body or your state.

Does it replace a course or training?

No. It's study and review material. It doesn't replace training, hands-on experience, the manufacturer's instructions or your state's code.

Are the practice questions the ones on the exam?

No. They're written for this book, in the style of the exam, with every answer explained. They aren't official exam questions.

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. No subscription.

Can I have it on paper?

We don't ship a printed copy. It's a PDF, sent by email, that you can print at home or at a print shop and 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.

Before You Close This Page

No more rereading pages that don't stick.
