A free Jedi test kit
Every attendee in the Dallas room receives one. It goes home with you on Thursday, so the first house you walk into on Friday gets tested.

The Dallas Class Starts Tuesday: What a Seat Includes, and the Three Extras on This Class
Three days, twenty seats, 8:00am to 5:00pm, in Roger Wakefield's home market after 45 years in the trade. Here is what the $5,000 seat includes, the three extras that are on the Dallas class only, the water the class is built on, and what happens to your seat if you applied for Carlsbad before the fires.
A $5,000 class is expensive right up until you sell the first one.
Short answer
Twenty Seats, Three Days, Three Extras
Dallas runs Tuesday November 3 through Thursday November 5, 2026, 8:00am to 5:00pm daily, twenty seats, $5,000 a seat. The seat includes all three days of instruction, the three certification exams, the HALO Certified Water Quality Expert credential, a water testing kit you keep, all course materials and catered lunch. Travel and lodging are the only cost on top.
On the Dallas class there are three extras: every attendee receives a free Jedi test kit, the second person from the same company is $1,000 off, and any company that sells a HALO system within two weeks after class earns a free HALO 5 system.
$1,000 off the second seat
The first seat from a company is $5,000. The second person from the same company is $4,000. One trained technician changes one route; two change how the shop talks about water.
A free HALO 5 system
Sell a HALO system within two weeks after class and your company earns a free HALO 5. HALO reports most of its graduates see their first sale within two weeks of returning home. The HALO 5 is earned inside that same window.
The three extras are the Dallas class offer as announced by the tour on 28 October 2026. Seats, tuition and dates are as published on the Dallas page.
The water
What the Dallas Class Is Built On
Every class is built on the host city's own water, and Dallas gives the class plenty to work with. The City of Dallas reports total hardness of 120 to 155 milligrams per liter as calcium carbonate, which is 7.0 to 9.1 grains per gallon (gpg). In Roger's own field tests in Dallas homes, readings typically run 8 to 12 grains. The Water Quality Association (WQA) classifies water above 7 grains as hard. Most of the country runs between 3 and 7.
| Measure | Dallas | Source |
|---|---|---|
| Total hardness, reported | 120 to 155 mg/L, 7.0 to 9.1 gpg | City of Dallas, memo to a council committee, 1 December 2023 |
| Field readings, Dallas homes | 8 to 12 gpg | Roger Wakefield, field tests |
| Classification | Hard | WQA scale: hard is 7 to 10.5 gpg |
| National typical range | 3 to 7 gpg | U.S. Geological Survey (USGS) Water Science School |
| Above EWG health guidelines | 17 contaminants, 12 of them disinfection byproducts | Environmental Working Group (EWG), an advocacy organization applying its own guidelines, stricter than the Environmental Protection Agency (EPA) enforceable limits |
| PFAS lawsuit filed | 14 January 2025 | City of Dallas v. 3M, DuPont and others, over PFAS (per- and polyfluoroalkyl substances) cleanup costs |
Being above an EWG guideline is not a legal violation, and Dallas Water Utilities reports compliance with federal standards. Both statements are true at the same time, and the plumber who can explain that in a kitchen, without dismissing the homeowner's concern and without inflating it, is the one who gets believed about everything else. Full breakdown with every source linked on the Dallas water quality page.
Three days
What Happens Tuesday, Wednesday and Thursday
Tuesday: water science and certification
Water chemistry and contaminants, reading a quality report like an inspector, field testing technique, HALO technology and why it works. The first certification exam closes the day.
Wednesday: product knowledge and presentation
Sizing and application, which home needs what. The core HALO systems, including the HALO 5, H2 Zero Ultimate, Hybrid, H2 Zero Carbon, Ultra Plus RO and CK10. A unit is in the room to see and touch. Nothing is installed. Second exam.
Thursday: selling water treatment
The water test as a sales tool, presenting without sounding like a salesman, pricing and packaging, the four objections that kill the sale, marketing water quality in your own town. Third exam, and the credential is awarded.
This is a knowledge class taught to people who already know how to hang equipment. Days one and two make you competent. Day three makes you money. The full day-by-day breakdown is on the curriculum page.
The math
Why One Sale Covers the Seat
$5,000
One seat, tuition. The second person from the same company is $4,000 on the Dallas class.
$6,000 to $8,000
One HALO system installed, the range HALO reports to the homeowner. One system recovers one seat with room left over.
Two weeks
HALO reports that most of its graduates see their first sale within two weeks of returning home, and that some recover $6,000 to $8,000 on their first day back in the field.
Those are HALO's figures, reported by HALO, and they are not a promise about what your technician will do. Your result depends on your market, your pricing and the person you send. The one-truck arithmetic, 780 calls a year at a 5 percent close rate, is on the revenue per truck calculator.
Carlsbad applicants
If You Applied for Carlsbad, Your Seat Is Not Lost
What happened
- The Carlsbad class set for October 27-29 was postponed because of the October wildfires in northern San Diego County, including the Henderson Fire at Camp Pendleton, which forced evacuations and closed Interstate 5 in the two weeks before the class.
- Carlsbad is rescheduling for early 2027. The new dates are announced on the Carlsbad page first, and everyone who has applied hears before the page does.
What happens to your seat
- It carries to the new Carlsbad date or to Dallas this week, your choice.
- We will call you. If you would rather be in Dallas on Tuesday, say so when we do.
- Nothing about your application has to be redone.
Who should drive in
Who the Last Seats Are For
The owner of one or two trucks
It should probably be you. You are the one in the houses and the one who sets pricing. Dallas is a drive, not a flight, for anyone in the Metroplex.
The technician who talks to homeowners
Not the fastest wrench in the shop. Water treatment is sold standing next to the water heater, in a conversation. Send the one homeowners already like.
The second person from the same company
$4,000 on the Dallas class. Send two so the capability survives one person leaving, and so they hold each other to it when they get back. Team pricing starts at three seats and is set on a call.
There is no approval wait. The application takes about two minutes, registration opens the moment you submit, and twenty seats are first come, first seated. Source: the application page.

Questions About the Dallas Class
When is the HALO Water Tour Dallas class?

What does the $5,000 seat include?

What are the extras on the Dallas class?
Three, on the Dallas class only: every attendee receives a free Jedi test kit, the second person from the same company is $1,000 off, so $4,000 instead of $5,000, and any company that sells a HALO system within two weeks after class earns a free HALO 5 system.
Is Dallas water hard?
Yes. The City of Dallas reports total hardness of 120 to 155 milligrams per liter as calcium carbonate, which is 7.0 to 9.1 grains per gallon. In Roger Wakefield's own field tests in Dallas homes, readings typically run 8 to 12 grains. The Water Quality Association classifies water above 7 grains as hard.
I applied for the Carlsbad class in October. What happens to my seat?
It carries to the new Carlsbad date in early 2027 or to Dallas, November 3-5, 2026, whichever you choose. We will call you. The October Carlsbad class was postponed because of the wildfires in northern San Diego County.
Do I need a plumbing license to attend?
No. There is nothing to install and no tools involved. This is a knowledge and presentation class for the people who run and grow plumbing companies. Installing water treatment equipment for customers is governed by your state and local licensing rules, not by this certification.
