There are two main types of root cutters--those that can be used with drain cleaning cable machines (blades) and those that can be used with sewer jetters (hydraulic).
Root Cutter Blade
Drain cleaning cable machines use a blade attachment which is held to the cable by a blade holder. Spartan Tool blades fit pipe sizes ranging from 2-6". The cable is fed down the line and then retrieved by the operator who removes roots from the blade. This process is repeated multiple times until the pipe is clear, and perhaps is the best practice for smaller, residential sewer lines with smaller cleanouts.
Spartan blades can be attached to either a 2’ leader cable or a double male coupling. To attach a cutter assembly, seat the base of the blade holder assembly onto the hex part of the leader or double male coupling. Next, place the proper blade size into the blade holder base. After inserting the blade, secure with blade retainer, lock washer and nut. Draw up all blade assemblies tightly with the T-wrench, otherwise vibration may cause unnecessary loss of blades.
Hydraulic Root Cutter
Spartan Tool is proud to be the originator of the hydraulic root cutter, which utilizes the power of a sewer jetter to quickly cut and clear roots and debris from sewer lines. Attached to the jetter hose and centered in the pipe using fins, these cutters are worked back and forth in the pipe until the obstruction is cleared.
In a recent discussion on Plumbers Forum, a satisfied customer provided this testimony about the power of hydraulic root cutters (and the power of our hydro jetters):
"I cleaned the roots from the sewer pipes with my Warrior Jet from Spartan at 3000 Lb. of pressure, and I also used a root cutter attached with spinal nozzle designed for the roots. I have done thousands of this type of application with success over many years. I also utilize a camera when I am cutting roots, leaving the entire pipe practically new. I find after using this type of new method, with several applications, with the right equipment and experience, the roots will stop growing. Jetting with a root cutter and camera works magnificently. It is the new way to clean pipes now. The use of the snake or cable application is the old school. Friends get with the program."
Cutting, tearing, and yanking, cutters like the 468 and the O’Brien fit pipe sizes from 4-15" and make use of adjustable flow rates from 10-60 GPM and pressures from 800-200 PSI to handle any task.
