I guess I'm new to the forum and don't want to ruffle too many feathers, but how many of the plumbers on this forum are familiar with how root removal with a hydro jetter works? I have a brand new 2001 machine that goes every where I go and works fairly well for most applications. The problem with any sewer machine is that they only remove 60 to 70% of the roots at best. We camera every job we do and the consensus is almost always the same. I you have a 4 inch clean out and it transitions to 6 inch pipe, the sewer machine just wont get all the roots out of the pipe. If the pipe has offsets and you have to use a smaller cutter, the result is even worse. Some customers root issues are so bad that they have to cable every 6 months to a year. When we us our hydro jetter the roots are totally gone from the pipe, that's why we offer a 3 year warranty. In the past 5 years that we've been using scrubbers, there have only been a handful of callbacks out of hundreds of customers! Jetting with a regular cleaning head would just clean the roots off and push the stoppage through, causing the roots to puff up. Using a root rat or warthog head cuts the roots flush with the edge of the pipe and removes all the roots out of the line. The roots eventually will grow back but it takes much longer than when we use a cable machine. There is a reason that we spent almost $50,000 on jetters and cameras.
