Mistakes to Avoid When Using a Sewer Jetter

A sewer jetter is one of the most effective tools for clearing pipe blockages, but even powerful equipment can fall short—or worse, cause damage—if not used properly. From choosing the wrong nozzle to skipping basic safety measures, mistakes can cost you time, money, and frustration. Understanding these common pitfalls and how to avoid them ensures your jetter machine performs at its best and keeps operations smooth and safe.

1.     Using the Wrong Nozzle for the Job

Not every blockage is the same, and not every nozzle works for every job. A penetrating nozzle slices through tough tree roots, while a flushing nozzle works better on grease and sludge. Using the wrong nozzle can result in wasted effort or even damage to your equipment.

Pro Tip: Always inspect and match your nozzle to the job at hand. A quick check ensures the right tool is ready for the task.

2.     Ignoring Pipe Material and Size

Pipes vary as much as blockages. Fragile materials like older PVC or clay can crack under high pressure, while tough industrial pipes may need extra force to clear debris. Ignoring these factors can lead to ineffective cleaning—or worse, costly damage.

Pro Tip: Know your pipe material and diameter. Adjust PSI settings and choose nozzles accordingly to protect pipes and maximize cleaning efficiency.

3.     Skipping Equipment Maintenance

Your power washer jetter works hard, but neglecting maintenance is like expecting a car to run forever without an oil change. Worn hoses, nozzles, and filters don’t just underperform; they’re prone to failure.

Pro Tip: Regular inspections make a big difference. Replace worn parts and clean filters often to keep your jetter running smoothly for years to come.

4.     Overlooking Safety Precautions

High-pressure water can cause serious injuries if mishandled. Skipping safety measures isn’t just a mistake—it’s a liability.

Pro Tip: Protective gloves, goggles, and boots are non-negotiable. Clear the area of unnecessary personnel and follow all safety protocols to avoid accidents.

5.     Forgetting to Flush Pipes First

Jumping straight into jetting without flushing the pipe is like trying to clean a clogged drain without removing the stopper. Loose debris can clog the system and reduce effectiveness.

Pro Tip: A quick water flush clears loose debris and lets you more accurately assess the blockage. Think of it as prepping the area for the main event.

6.     Neglecting to Secure the Hose

An unsecured hose can whip around dangerously under high pressure and cause damage or injury.

Pro Tip: Use hose guides or clamps to keep everything stable. This simple step protects your equipment and ensures a controlled, efficient operation.

7.     Applying Too Much Pressure

High pressure might seem like a quick fix, but pushing the limits can lead to pipe blowouts or further damage, especially in older systems.

Pro Tip: Start with a lower PSI and gradually increase based on the blockage and pipe condition. Balance power with precision to get the job done right.

8.     Failing to Inspect Pipes Beforehand

Jetting damaged pipes can make an already bad situation worse, turning small cracks into major breaks.

Pro Tip: Use a camera or other inspection tools to assess pipe condition before starting. A little preparation goes a long way in avoiding costly repairs.

9.     Retrieving the Hose Too Quickly

Yanking the hose back too fast can leave debris behind or strain the equipment.

Pro Tip: Take your time. Slow, even retrieval ensures a thorough cleaning and prevents unnecessary wear on the hose.

10.Skipping Proper Training

Sewer jetters are powerful tools that require skill and knowledge to operate effectively. Without training, operators risk inefficient cleaning, equipment damage, or injury.

Pro Tip: Invest in training for everyone who operates the jetter. Understanding the equipment inside and out leads to safer, more effective results.

11.Misusing the Jetter

Sewer jetters are designed for clearing pipes, not for tasks like surface cleaning or unrelated heavy-duty applications. Misusing the equipment can void warranties or cause irreparable damage.

Pro Tip: Stick to manufacturer guidelines and use the jetter only for its intended purpose. If you need a versatile tool for general cleaning, consider a vac pressure washer as an alternative.

Conclusion

Using a sewer jetter effectively is about more than just turning it on. By avoiding these common mistakes—like skipping maintenance, ignoring safety measures, or using the wrong nozzle—you can extend the life of your equipment and get better results with every job. With the right preparation, proper training, and attention to detail, a sewer jetter becomes an indispensable tool for tackling even the toughest clogs. Take the time to do it right, and you’ll save yourself frustration, downtime, and unnecessary expenses.
