Welcome to the JetterProSupply Training Center — a free, no-login library built for people who clean drains for a living. Everything here is written by folks who actually jet: how the tools work, how to match them to your machine, how to run the jobs, and how to make money doing it. No fluff, no gated "webinars," no upsell to a course. Just the reference material we wish we'd had when we started.
Our nozzles are engineered in Germany and assembled in America (Spartanburg, SC) by KEG Technologies — so the guidance below is grounded in real specs, not sales copy. Bookmark this page; we add to it constantly.
How to Use This Center
You don't have to read it front to back. If you're brand new, start with the learning path just below and work down it in order. If you already jet and you're here for a specific answer — grease, roots, a stuck nozzle, pricing a job — jump straight to that section using the headings. And if you'd rather talk to a person than read, the phone number at the bottom reaches someone who actually runs this equipment.
A suggested learning path if you're getting into jetting:
- Understand what jetting is and when it beats a cable — What Is Hydro Jetting? then Jetter vs Snake.
- Learn the physics so nozzle choices make sense — The Science of Pipe Cleaning.
- Match a nozzle to your machine — run the Nozzle Selector and read What GPM & PSI Do I Need?
- Learn to run the common jobs — grease, roots, mainlines (sections below).
- Cut your cost per job with inserts — the Inserts Hub and ROI Calculator.
- Turn it into revenue — the Growing the Business section.
Start Here: Interactive Tools
If you only use three things on this site, use these:
- Nozzle Selector — answer a few questions about your machine (GPM/PSI), hose size, and the job, and get matched to the right nozzle in about a minute. The fastest way to stop guessing.
- ROI Calculator — plug in your jobs per week and see the real per-job math on replaceable inserts vs. throwaway nozzles. This is the number that decides whether jetting makes you money.
- Inserts Hub — everything on replaceable ceramic and steel inserts: how they work, how they save you money, and where to restock. Don't change the nozzle, change the inserts.
The Nozzle Guides
Each KEG nozzle family has a full guide — what it does, which jobs it's for, and which machines it fits. Learn the lineup and you'll always reach for the right tool:
- The Complete Guide to Sewer Jetting Nozzles — the master overview; start here if you're new to the lineup.
- Cleaning Nozzle Guide — the everyday workhorse for general mainline clearing.
- Penetrating Nozzle Guide — Rambo, Quattro & Egg Devastator for cutting into tough blockages.
- Rotor Nozzle Guide — rotating jets for descaling and the finishing step before the camera.
- Traction Nozzle Guide — steep grades and long pulls where you need the nozzle to keep advancing.
- Egg Nozzle Guide — the compact all-rounder that rides over debris and flushes grease.
- Duce Nozzle Guide — descaling, grout & tuberculation.

Grease & Restaurant Work
Grease is the most profitable recurring drain call in the trade — restaurants, apartment kitchen stacks, and commercial food lines clog on a predictable schedule, which makes them ideal recurring-maintenance accounts. The trick is a nozzle configuration that peels grease off the wall and flushes it out rather than boring a hole through it. Learn to own this work:

- How to Jet a Kitchen Drain Line (Step by Step)
- Restaurant Floor Drain Maintenance: The Complete Playbook

Roots, Scale & Tough Blockages
Roots and hard scale are where technique and the right nozzle matter most — the wrong approach wastes flow, packs debris tighter, or leaves you making four passes where one should do. These guides cover the rotary cutting, penetration, and flushing sequences that actually clear the line:

Inserts & Cutting Your Cost Per Job
This is the section that pays for itself. Every nozzle wears; the orifices erode and the nozzle that used to pass on the first try starts taking three or four. The difference between a pro tool and a throwaway is what you do next — swap a couple-dollar insert, or buy a whole new nozzle. Learn to run inserts and you stop bleeding money on worn-out tools. Don't change the nozzle, change the inserts.
