Efficiency and jetting performance is crucial in plumbing. Every equipment upgrade can make a noticeable difference, especially with jetting systems used to clear drains. One such upgrade that can significantly improve performance is switching from a 25-horsepower (hp) or 27-hp engine to a 31-hp engine. But how does this boost affect performance, and is it worth the investment? Let’s break it down.
Jetting System Basics
Jetting systems combine pressure (PSI) and flow (Lpm) to clear blockages in pipes.
Many plumbers in Australia rely on water jetting machines with 25-27hp engines, running at 5000 PSI with 20-25LPM. While this works for small to medium jobs on residential drains up to 150mm—sometimes 225mm, upgrading to a 31hp engine with 31LPM at 4300 PSI can offer major advantages—especially for larger jobs.
Why Flow Matters
Higher flow rate (LPM) improves the cleaning process by moving more water through the system, making root cutting and debris flushing faster and more efficient. This upgrade is particularly useful for larger pipes, between 225-300mm in diameter.
The Upgrade: What Changes with a 31HP Engine?
A 31-hp engine increases the flow rate while slightly lowering the PSI. The flow jumps from 23 Lpm to 31 Lpm, though the pressure drops to 4300 PSI. While this may not seem like a huge difference, in the world of jetting, the increased flow matters. It allows more water to move through the system quickly, boosting the cleaning power of the jetter.
This higher flow rate helps dislodge more debris and push it through the pipe more efficiently. The change is especially valuable for larger or more heavily clogged systems. This is where the extra power of a 31-hp engine shines.
Key Benefits of Upgrading to a 31HP Engine
So, what exactly do plumbers gain by upgrading to a 31-hp engine? Let’s explore the specific advantages.
- Better Root Cutting & Flushing
The higher flow helps move more stubborn debris through the pipe. This is particularly useful for rootcutting and flushing, and allows plumbers to use powerful nozzles. - Handle Larger Pipes
The 31-hp engine allows plumbers to handle larger drains, up to 300mm in diameter. This opens up opportunities to take on more complex and higher-paying jobs. - Quicker Job Completion
The increase from 23 Lpm to 31 Lpm means more water is moving through the system. This leads to faster job completion since blockages are cleared more quickly. - Extended Equipment Life
Upgrading to a 31-hp engine reduces strain on the jetting system. The increased efficiency means the equipment doesn’t have to work as hard, which can extend its lifespan and reduce maintenance costs.

Is the Upgrade in Jetting Performance Worth It?
For plumbers working primarily on smaller residential drains, the 27-hp system like the Viper X or Viper S-line may suffice. But for those handling larger drains or looking to expand their services, the upgrade to a 31-hp engine offers clear advantages. The increased flow and ability to take on bigger jobs make it a solid investment. It helps plumbers complete tasks faster, handle tougher blockages, and expand their capabilities.
Conclusion
Upgrading plumbing equipment to a 31-hp engine system can significantly improve jetting performance. The increased flow and power make clearing drains quicker and more efficient. For plumbers ready to take on larger projects and improve their efficiency, this upgrade is a smart move. By leveraging the full potential of the 31-hp system, they can unlock faster cleaning times, better debris removal, and a broader range of job opportunities.
