A cable punches a hole through a blockage. A jetter scours the pipe wall back toward its original bore. On a greased-up line, that difference is months versus years.
There is a reason a kitchen drain gets cleared and then blocks again the following spring. The cable made a hole; the hard layer of cooled grease lining the pipe never moved, and it starts catching debris the same day.
Jetting attacks that layer directly — high-pressure water through a head that drives forward and washes backward, cutting the deposit off the wall and carrying it away.
It is not the right tool for every line, and we would rather look first than find out the hard way on brittle pipe.
Blocked drains rarely travel alone. Here is what else we handle.
Camera first, so jetting is the right answer rather than a guess.
