DIRTY PLUMBERS — Episode 3: It's a FACT: Large Plumbing Companies Have More "Sales People" Than Certified, Skilled, and Experienced Plumbers

 We touched on this back in April — large plumbing companies aren't always what they appear to be. But today we're going deeper. Because the more you understand how these operations actually work, the better equipped you are to protect your home and your wallet.

You call a big-name plumbing company. A truck shows up. Looks professional. Uniformed guy at the door. You feel good about it.

But here's what they don't tell you: that person at your door may not be a plumber.

Large and franchise plumbing companies frequently operate on a tiered workforce model — and the person sent to your home first is often what the industry quietly calls a Sales Technician. Great at diagnosing problems. Even better at selling you on expensive solutions. But licensed? Experienced? That's a different story.

Here's how the tiers typically break down:

Tier 1 — The Sales Tech
This is who shows up first. Their job is to assess the situation, build rapport, and present you with options — usually ranging from "basic fix" to "full replacement." They're trained in sales psychology, not pipe systems. Their commission depends on what you say yes to.

Tier 2 — The Apprentice
If actual work gets done, it may be performed by an apprentice — someone still learning the trade, working under a license that belongs to someone else who may never set foot in your home.

Tier 3 — The Licensed Plumber
These exist at large companies, but they're often supervisors, estimators, or reserved for complex commercial jobs. They're not the ones crawling under your sink.

Why does this matter?

Because plumbing done wrong doesn't just fail — it causes water damage, mold, code violations, and in some cases, health hazards. A bad solder joint. A vented drain installed incorrectly. A water heater with improper pressure relief. These aren't small mistakes.

When a licensed journeyman or master plumber shows up, you're getting someone who has spent years in the field, passed state exams, and carries personal accountability for their work. That's not what you always get from a franchise dispatch call center.

What should you ask before you let anyone touch your pipes?

  • Are you a licensed plumber? (Not just "does your company have a license")
  • What is your license number?
  • How long have you personally been doing this type of work?
  • Will you be the one doing the work, or will you hand it off?

A real plumber won't flinch at those questions. A sales tech will change the subject.
