3 Types of Hydro-Jetter Users: Which One Are You?

You’re in the shop or on a job, the phone rings, and it’s a contractor asking the same question we hear all the time: “What size jetter do I actually need?” 

The truth is, there isn’t one answer. The "right" jetter setup depends on where you are in your business, what jobs you’re running, and what you’re trying to grow into next. We see three types of jetter buyers every day: the First-Timer, the Upgrader, and the Expert.

By the end of this breakdown, you’ll know exactly which category you fall into and what direction makes the most sense for your next move.

Type 1: The First-Time Jetter Owner

If you’re just getting into hydro-jetting, this is where most operators start. It’s about learning the equipment, taking on jetting work that you’ve been passing off, and building confidence on real jobs.

Where "First-Timers" Are Typically At

You’re either snaking lines or turning jetting work away altogether, maybe referring jobs out and watching someone else collect the revenue, and you’re ready to bring that work in-house so you can take control of your schedule, capabilities, and bottom line.

Common Concerns

The questions usually sound like this:

• How much jetter GPM and PSI do I really need?
• What's an easy-to-use jetter that we can get started with?
• Am I going to buy too much machine or not enough?
• How do I stay within budget but still get real capability?

What "First Timers" Typically Need

At this stage, simplicity wins, you need a proven jetter that works, clear guidance on what the machine can handle, and a setup that gets you on jobs right away without overthinking every detail.

Recommended Direction

If you just want to get your feet wet in jetting, start with a simple, easy-to-use electric jetter for indoor small-drain jetting work. It’s a low barrier to entry and a solid way to add jetting-job revenue while also learning how high-pressure water-jets can be a unique and effective cleaning tool.

If you want to step into sewer work, you’ll need to move into gas-powered jetters in the 3000–4000 PSI range. That’s where you start gaining real cutting ability.

If you want to offer true “rooter-class” jetting, step up to a 7+ GPM machine and pair it with the right nozzles for roots, grease, and buildup.

PRO TIP: You don’t need every tool, just the right tools for the jobs you plan to take on.

Type 2: The Upgrader

You’ve already been jetting for a while, but you have hit the ceiling of what jobs your size of jetter can do. This stage is all about pushing past limitations, taking on bigger work, and increasing efficiency on every job, so you're interested in "next level" jetting equipment.

Where "Upgraders" Are Typically At

You already own a jetter, but it’s GPM/PSI output (or lack of output) is holding you back. You’re still referring out bigger jobs, and while your customer base is growing, your equipment isn’t keeping up.

Common Frustrations

This is where things get real:

• You can’t clear lines that competitors with bigger jetters handle with ease
• Your jetter doesn’t have enough GPM to run aggressive nozzles effectively
• Jobs are taking too long, cutting into profit

What "Upgraders" Typically Need

Now it’s about jetting power and capability: you need more GPM for impacting blockages and flushing action, enough PSI for cutting action, and nozzle setups that can actually attack tougher blockages instead of just poking into them.

Recommended Direction

This is where stepping up in equipment changes your business.

Move into higher GPM and PSI configurations. A van-pack or trailer jetter opens the door to real rooter-class work and commercial jobs.

Expand your nozzle lineup. Tools like the Reaper and Warthog are designed to cut and scour, not just clear soft clogs. Add chain scrapers when you’re dealing with scale and heavy buildup.

Real-World Example:

A contractor upgrades from a 4 GPM converted pressure washer to a 9 GPM / 4000 PSI jetter with premium nozzles. Suddenly, they’re cutting out tree roots efficiently, clearing grease buildup routinely, and even handling 6″–8″ lines without referring work out.

That’s the shift from surviving jobs to owning them.

IMPORTANT: Growth without the right jetter GPM/PSI specs leads to frustration. A jetter's PSI dictates water-jet velocity and penetrating action, but it's the jetter's GPM flow that ultimately determines water-jet impact and what range of pipe-sizes it can efficiently clean for you. Match the jetter's GPM to the pipe sizes you clean most often by choosing at least 2-GPM per inch of pipe-diameter (e.g. 8+gpm for 4" pipes, 12+gpm for 6", etc.).

Type 3: The Expert

At this point, jetting isn’t something you’re learning, it’s something you’ve mastered. Now the focus shifts to dialing in performance efficiency, minimizing downtime, and getting the most out of every setup you run.

Where "Experts" Are Typically At

At this level, you already know what you need, you understand GPM, PSI, hose size, and nozzle selection. You might be running multiple crews and managing several machines, with a nozzle arsenal that can attack all sorts of blockages and buildup in pipelines of many sizes.

What "Experts' Typically Care About

This isn’t about entry-level decisions anymore. It’s about performance, uptime, and growth.

• Tailored setups that match your growing scope of work
• Hose reels, tank sizes, and control systems that improve efficiency
• Nozzles calibrated correctly for each jetter and hose-size in your fleet

What They Expect

You want straight answers and equipment that performs day in and day out, because downtime isn’t an option and neither is guesswork.

Recommended Direction

At this stage, you’re investing in capability and consistency, with higher GPM trailer or skid units to handle larger commercial and industrial jobs, a full lineup of premium nozzles to be ready for anything, and a focus on redundancy, spare parts, and maintenance routines that keep your crews moving.

PRO TIP: At this level, downtime costs more than equipment. Invest accordingly.

How to Choose the Right Setup for Your Stage

Step-1: Identify the Most Common Pipe Sizes You’ll Be Jetting

Your GPM needs should match the diameter of the lines you work in most often. Bigger pipe requires more flow to clean efficiently. Minimum 2-GPM per inch of pipe-diameter is need to provide "rooter-class" jetting services. 

Step-2: Define Your Typical Blockages

What are you actually dealing with day to day?

• Roots?
• Grease?
• Wipes?
• Process buildup?
• Debris and Scale?

Different problems require different "nozzle logic" and different levels of power.

Step-3: Decide on Jetter Mobility

Think about how you operate:

• Van-pack jetters for mobility and everyday service work
• Tow-behind trailer jetters for higher water capacity and bigger jobs
• Wireless Remote Controls for maximum indoor/outdoor jetting efficiency
• Portable cart jetters and mini-jetters for tight access and indoor work

The right setups fit your workflows, not the other way around.

Identify Where You Are and What You Need to "Get" Jetting at Your Level ... and the Next Level !

Most every jetter buyer falls into one of these three categories: First-timers are just getting into the jetting game. Upgraders are expanding their jetting capabilities. Experts are dialing in their jetting fleet and tools for efficiency, uptime, and growth.

It's been said that "Success begins with being honest with yourself", thus the key is knowing where you really are right now and choosing equipment that supports where you’re going next. Water is your tool. When you match the right GPM, PSI, and nozzle setups to your work, everything changes. Jobs get done faster, pipes are cleaner, customers become long-term clients, and your hydro-jetting services becomes more and more profitable.
