Every jetter clears lines. The difference between machines usually comes down to how big the jobs are and how long you need to run before refilling water. Choosing the right one is tough. Before you start, ask yourself these three simple questions: “What Kind of Jobs Are You Running? How Long Do You Need to Run Before Refilling? What Work Am I Doing?”

There’s a lot of information here. If you want to just cut to the chase, you can always call your dealer or speak with one of our technicians. If now, here you go!
Ask yourself:
1. What Kind of Jobs Are You Running?
Start with the work you do most days.
Service Plumbing
These crews usually prefer compact jetters mounted on trucks or small trailers.
- Residential drains
- Restaurants and grease lines
- Small commercial sewer lines
Typical pipe sizes: 2″–8″
What matters most:
- Easy to maneuver
- Quick setup
- Reliable pressure
- Water flow
Commercial Sewer Cleaning
These crews usually move up to mid-size trailer jetters.
Typical jobs:
- Apartment complexes
- Shopping centers
- Industrial facilities
Typical pipe sizes: 6″–18″
What matters:
- Higher flow
- Longer cleaning runs
- More water capacity
- Higher pressure
Municipal Sewer Maintenance
Municipal crews usually run larger trailer jetters built for longer shifts.
Typical jobs:
- City sewer lines
- Storm drains
- Preventative flushing
Typical pipe sizes: 8″–24″+
What matters most:
- Large water tanks
- High flow
- Long runtime
2. How Long Do You Need to Run Before Refilling?
Water capacity matters more than most people expect. Small service calls might take 10–15 minutes of jetting. Municipal flushing can run hours at a time.
A bigger tank means:
- fewer refill trips
- more work per stop
- less downtime during the day
3. What Work Am I Doing?
This is usually the final deciding factor.
Truck / Van Jetters are best for service plumbers.
Why?
- Always with the truck
- Fast setup
- Compact
Typical jobs: Residential and commercial drain cleaning.
Trailer Jetters are best for bigger jobs.
Why?
- Larger water tanks
- Higher flow
- Longer operating time
Typical jobs: Municipal and large commercial work.
