What Is a Drain Line Jetter?
A drain line jetter is a high-pressure water system mounted on a trailer or skid that blasts through blockages, bio-film, grease, roots, and debris in sewer and drain lines. Unlike a snake that punches a hole through a clog, a jetter cleans the pipe wall to wall — which means fewer callbacks and higher-value jobs.
The basic components are a water tank, a high-pressure pump, a hose reel, and a set of nozzles. The rest is engineering — and that’s where manufacturers separate themselves.
- Typical applications: residential sewer lines, grease traps, commercial drains, storm drain maintenance, municipal laterals
- Typical line sizes: 2″ to 18″ pipe diameter depending on machine capacity
- Revenue per call: Jetting jobs average $1,500 vs $250 for a snake run — same truck, same hour, 6x the revenue
If you’re reading this and still sending technicians out with just a cable machine, you’re leaving real money behind every single day.
Hot Water vs Cold Water — Which Do You Need?
This is the most important decision in drain line jetter selection and most buyers get it wrong. Here’s the straight answer:
Cold water jetters are powerful enough for roots, sand, debris, and most residential blockages. If you’re doing mostly storm drain work, residential lines, and jobs where grease isn’t the primary culprit — a cold water machine will get it done at a lower price point.
Hot water jetters add a propane or diesel burner that heats the water to 185–195°F. That heat doesn’t just move grease — it emulsifies it. F.O.G. (fats, oils, and grease) solidifies at room temperature inside a drain. Cold water pushes it downstream. Hot water dissolves it. Big difference when you’re doing restaurant accounts or any commercial kitchen work.
The contractors who make the most per hour own a hot water machine. Period.
| Feature | Cold Water Jetter | Hot Water Jetter |
|---|---|---|
| Grease clearing | Pushes downstream | Emulsifies and dissolves |
| Price range | $39,995 – $54,995 | $52,995 – $79,995 |
| Best for | Residential, storm drains, roots | Commercial, restaurants, grease traps |
| ROI per call | High | Higher — premium job pricing |
| Fuel needed | Gas or diesel (pump only) | Gas/diesel + propane or diesel burner |
GPM and PSI: The Numbers That Actually Matter
Every jetter spec sheet lists two numbers: GPM (gallons per minute) and PSI (pounds per square inch). Buyers obsess over PSI — but experienced contractors know that GPM is the number that cleans the pipe.
- PSI cuts the clog. It gives you penetration power against roots, hardened grease, and compacted debris.
- GPM flushes the debris. Without enough flow, you break up the clog but don’t move it out of the line. That’s how you get callbacks.
For residential work (3″ to 6″ lines), 7–10 GPM at 3,000–4,000 PSI is the sweet spot. For commercial and municipal lines (8″ to 18″), you want 18+ GPM to actually evacuate debris from longer, larger pipe sections.
The HotJet II runs 10 GPM at 4,000 PSI — the workhorse spec for the majority of plumbing and drain cleaning contractors. The HotJet III / XtremeFlow III jumps to 18 GPM at 4,000 PSI for heavy commercial and municipal work.
Trailer Mounted vs Skid Mounted
A trailer mounted jetter is self-contained and hitch-ready — you pull it with a truck and deploy on-site. Best for contractors who run dedicated jetting rigs and want maximum tank capacity and hose reel flexibility.
A skid mounted jetter sits in the bed of a truck or van. More maneuverable in tight urban areas, easier to position at commercial buildings with loading dock access. Trade-off is water capacity and hose reel length.
For most new jetting contractors, the trailer is the right call. You get more water, more hose, and the ability to run longer jobs without stopping for a refill. When your business grows, a skid mount makes sense as a second unit for a different truck and a different technician.

What Contractors Get Wrong When Buying a Jetter
After shipping over 1,000 units, we’ve seen the same mistakes repeat. Avoid these:
- Buying on price alone — A cheap machine from a P.O. Box company breaks down on job sites, has no parts support, and costs you customers. The jetter you buy is the business you build.
- Skipping training — A jetter at 4,000 PSI in untrained hands is a liability, not an asset. All HotJet USA purchases include a full training day. Take it seriously.
- Under-estimating hose requirements — Most residential sewer lines need 200–300 feet of hose. Don’t buy a machine with 150 feet and find yourself short on your first job.
- Ignoring the camera upsell — A sewer camera paired with a drain line jetter turns every job into a diagnostic opportunity. Every jetting call becomes a potential camera inspection. That’s double the revenue from the same driveway.
- Waiting too long to buy — Every week you run cable-only is a week of jetting revenue you didn’t collect. HotJet USA offers financing — a machine that generates $150,000+ per year should not wait on a budget cycle.

Frequently Asked Questions
How much does a drain line jetter cost?
HotJet USA drain line jetters range from $39,995 for the XtremeFlow II cold water trailer to $79,995 for the HotJet III municipal-grade dual-engine unit. The most popular machine for plumbing contractors is the HotJet II at $52,995. Financing is available — most contractors find the machine pays for itself within the first 90 days of regular jetting work.
Do I need a hot water or cold water jetter for restaurant grease trap work?
Hot water is the right call for F.O.G.-heavy work. Cold water will move the grease but hot water emulsifies it, which means it won’t re-solidify downstream. If you’re targeting restaurant accounts, food processing facilities, or any commercial kitchen work — go hot water. You’ll also command higher job rates because fewer contractors can do the work properly.
What’s the minimum GPM I need for a productive jetter?
For residential drain lines (3″ to 6″), 7–10 GPM at 3,000+ PSI is the practical floor. Below that and you’re fighting flow rate on longer line runs. For commercial or municipal work, step up to 15–18 GPM. The HotJet II at 10 GPM handles 90% of residential and light commercial jobs without issue.
Can I finance a drain line jetter?
Yes. HotJet USA works with financing partners to get contractors into equipment quickly. Visit hotjetusa.com/financing or call us and we’ll walk you through the options. Most contractors are cash-flow positive within the first quarter.
