One avoidable mistake can cost more than this whole library.

Time

Hours count {{fact:apprentice.hours_start}}. Work a year before you register and that year earns no credit toward your license.

Fines

Texas can fine {{fact:penalty.civil}} per violation, and per day after notice. A missing line on an estimate or a truck is a violation.

Money

On example numbers, charging $90 an hour when your real cost is $120.24 loses $30.24 on every hour you bill. A busy shop can still lose money.

The playbook costs $100, once.

Built by a plumber who learned it the hard way.

Christian Mejia, Master Plumber

At 18, I was out of my parents' house with no real high school education to show for it, a screwdriver and a plastic bucket. I dug trenches ten hours a day before anyone let me set a toilet.

I made every rookie mistake. I flooded a bathroom, cracked toilets, and lost months of apprenticeship credit by not logging my hours with the state.

I took each license the day I could, went out on my own as a subcontractor, and earned my Master license at 25.

Nobody handed me a playbook. This is the one I wish I'd had.

Your path, one step at a time.

From your first day on the job to your own company. Every number cited.

  1. Apprentice

    Register first, then every hour counts. Start as early as {{fact:apprentice.min_age}}, even in high school.

  2. Tradesman-Limited

    An optional stop for {{fact:tradesman.scope}}. {{fact:tradesman.hours}} and the exam.

  3. Journeyman

    {{fact:journeyman.hours}} and {{fact:journeyman.training}} of training, then the exam.

  4. Master

    {{fact:master.experience}}, then the exam.

  5. Owner

    A company needs a Master's license behind it, with {{fact:rmp.insurance_min}} of insurance on file.

Then, your first 90 days

A Journeyman license alone does not let you run a company. It does open four legal routes. The playbook shows each one, and the order to do things.

  1. Day 1Choose your route
  2. Day 30Protected: insurance and agreements
  3. Day 60Set up: company, bank, trucks, estimates
  4. Day 90Working: first jobs costed, numbers on

Everything you need, in order.

Built for the phone in your truck. One lesson at a time, with a plain-words summary on every one.

    It's for

    Apprentices, Tradesmen, Journeymen and Masters who want their own work, and new owners with one to three trucks.

    It isn't

    A board-approved course, plumbing instruction or exam prep. Not legal, tax or insurance advice. No income promises.

    Questions, answered.

    Can I run my own plumbing business as soon as I have my Journeyman license?
    Not by yourself, and anyone who tells you otherwise is guessing. In Texas a company needs a Responsible Master Plumber to offer plumbing to the public, and only that Master pulls permits. A Journeyman can still run their own work legally: as a subcontractor under a written agreement, or by owning a company that employs a Master as its RMP, or by becoming a Master after two years. The playbook shows each route and its numbers.
    I'm in high school. Can I use this?
    Yes. In Texas you can register as a plumber's apprentice at {{fact:apprentice.min_age}}, and hours count only after you register. There is a lesson called "Starting at 16" with the steps, an example of how the hours add up, the child labor rules for workers under 18, questions to ask an employer, and a section for parents.
    Is it worth $100?
    A single violation can carry a fine of {{fact:penalty.civil}}, and a wrong hourly rate loses money on every hour you bill. The library also saves you the hours it takes to read the statute and the board rules yourself. Only you can say whether that is worth $100, which is why the planner, a full lesson and twelve AI prompts are free to try first.
    How is this different from blogs and videos?
    Every Texas rule links to the statute or board rule it came from, with the date it was checked. It adds calculators for your real numbers, templates, and a plan in order. Where sources disagree, it says so instead of picking one.
    Is the information current?
    Every Texas fact carries the date it was checked and a link to its source. Where the licensing board's own pages disagree, or a change is only proposed (for example the move to the 2021 plumbing codes), we flag it. You get 12 months of updates.
    Does it count toward training, continuing education or the exam?
    No. Only providers and instructors approved by the Texas State Board of Plumbing Examiners can deliver those. This library explains the requirements and teaches the business side. It has no exam questions and no plumbing technique.
    Is it only for Houston or Dallas?
    The licensing, insurance and paperwork rules here are statewide. Each city adds its own permits and codes. The library teaches how to check yours and gives you a one-page sheet per city.
    Does it cover marketing and AI?
    Yes. There are lessons on getting customers (your Google profile, reviews, local ads, referrals, call handling, and the rules your ads must follow) and on using AI in your business, with the legal rules and a prompt library.
    Can my whole crew use one purchase?
    A purchase is for one person on up to 3 devices. Crew licenses are planned.
    What if I find a mistake?
    Tell us. The Accuracy Promise means we correct a reported rule error within 7 days.
    What is your refund policy?
    All sales are final because you get everything instantly. That is why there is a free lesson, a free planner and previews of every template. Four exceptions: an accidental purchase you never unlocked (within 24 hours), a billing error, an access failure we can't fix, or a missing feature or material error we don't correct. Read the policy.
    Is this legal advice?
    No. It's educational information. For contracts, taxes and insurance, talk to a Texas attorney, a CPA and an insurance agent. The library tells you when.
    Who is behind it?
    Christian Mejia, a Texas Master Plumber who started as an 18-year-old helper and went out on his own as a subcontractor. His story is in the section above. The rules in this library come from the Texas statute and the plumbing board, not from memory.
