Our sewer jetters — also called jetter trucks, hydro jetters, or water jetters — use high-pressure water to clear blocked underground sewer and drain lines, from 50mm up to 900mm in diameter and more. A specially designed nozzle delivers high-pressure water into the line to break up and clear the blockage. Depending on tank and pump capacity, units are built on truck, trailer, or towable chassis to fit different fleet needs. Beyond core sewer jetting, these machines can also be used for pressure washing equipment and vehicles, cleaning walkways, and other general high-pressure cleaning tasks.
High pressure jetting is the preferred method of re-establishing water flow. It not only removes blockage but also washes away all debris found within the pipe. High pressure water jet is faster and less labor intensive than use of a mechanical rodding or cable machines. High pressure jetting units maintain constant working pressure and cleaning power at the nozzle end while mechanical machines will lose cutting and torque power as rod or cable distances increase within pipelines from the point of entry.
High pressure jetting has another advantage over cable or rodding machines. Where access is difficult, a lightweight, flexible jet hose is a safer and more practical solution. Pipelines that are suspended from ceilings or catwalks are easily cleaned using a high pressure jetting hose rather than a heavy, cumbersome mechanical drain cleaning machine. Cleaning vertical stacks or vents is easier with a high pressure jetting unit and lightweight jetting hose than with heavy drain cleaning cables or rods.

The right sewer jetter for a job comes down to the pump's flow and pressure relative to the diameter of the line being cleared. Higher flow moves more debris out of larger-diameter pipes; here's how the MJ-series lines up:
Every MJ-series sewer jetter ships standard with two nozzle types:
Additional nozzle types can be supplied to match specific jetting jobs, including:
Match the diameter of the line you need to clear against the flow/pressure table above. Larger-diameter lines need higher flow to carry debris out effectively, which is why capacity increases from the compact MJ-500 up to the high-flow MJ-8000.
Conical Head and Round Head nozzles, both with front and rear holes, are standard on every model. Specialty nozzles such as penetrators, root cutters, descaling nozzles, and rotating nozzles can be supplied to match specific jobs.
Yes — a camera can be fitted in place of the nozzle on any MJ-series jetter, with both live view and recording.
The MJ-3000, MJ-6000, and MJ-8000 can be fitted with a hose counter, available as either a mechanical meter-wheel counter or a digital footage counter.
