If a drain here clogs repeatedly, you are dealing with a coated pipe rather than a single obstruction, and cabling will not solve it.
Long runs collect more
Large Mount Pleasant floorplans mean long drain runs with shallow falls. Grease and residue accumulate along that length rather than at one point, which is exactly the situation where a cable passes through and leaves the problem behind. Jetting scours the full run back to the pipe wall.
Scale in the older streets
Cast iron in Old Village properties narrows with decades of deposit. Jetting addresses the material directly instead of making a channel through it.
Root cutting follow-up
After roots are mechanically cut, jetting clears the fine residual material that would otherwise catch the next thing down the line. It is what makes the interval between calls longer rather than shorter.
When we will decline
Old cast iron or clay that has already lost wall thickness may not take the pressure. That is what the camera inspection is for, and on a compromised line we will recommend lining rather than risk turning a blockage into a failure.
