Hydro jetting machines face many challenges in the pipelines in the field. Debris ranging from sludge, rocks, and grease are all common applications that a jet operator might tackle. One particularly common opponent is roots that have worked their way into the pipe. Since pipelines are run underground and have water running through them, roots often penetrate through tiny cracks to access this water and result in major problems in a pipe. To handle this problem, only a high pressure jetting machine can do the job right.
Root Cutters for Jetters
Roots in a pipeline can cause problems whether they are fine hair-like roots or huge chunks of root balls that have worked their way into the pipe. Even fine roots can cause blockages in a pipe that result in flooding or clogging. This type of job is not something that a snake or cable can properly handle, because this debris requires being fully cut up and then flushed back down the pipe.
The best way to tackle roots in a pipe is with a hydro jetting machine. These jetters use high pressure water to cut through the roots and flushing power to push the debris back and open up the line. It’s important to use the right nozzle to tackle these jobs to make the most efficient jetting work.
Sewer Nozzles for Root Cutting
The most popular jetter nozzle for cutting through roots is the Flexible Super Spin aka Warthog nozzle. This nozzle has a forward angled jet which penetrates tough debris while the two rear jets propel the nozzle up the pipe and flush debris back. The nozzle head has an oil lubricated controlled rotation which makes the nozzle spin to perfectly provide 360 degrees of cleaning. This nozzle is not only ideal for roots but also easily tackles grease and other difficult debris.
As an alternative, some jet operators prefer the Reaper or Rotodrill Nozzles when tackling roots. The Reaper has a zero degree rotating front jet that slices through roots while the four rear jets blasts back the debris. The Rotodrill has one front orbital jet which is key for cutting through dense debris while the six rear jets simultaneously flush back material while pushing the nozzle up the pipe. With any sewer nozzle designed for cutting roots, the rotating front jet is crucial for cutting through any tough clogs.
Why You DON’T Need Heavy-Duty Chain Cutters for Root Cutting
It is a common misconception that chain cutters, chain flails, or chain nippers are necessary for cutting through roots. While this is understandable, because visually it would seem that chains are ideal for cutting roots, but it’s simply not the case. More often than not, chains damage the pipe when used incorrectly. Chain flails should really only be used when descaling cast iron pipes, because otherwise the chain flail is so aggressive it will tear up the pipe. Using a rotary nozzle with a front jet for penetration is the only way to go with tackling roots.
