What this service solves
A flex shaft machine drives a flexible cable with a rotating chain knocker or blade head that scrapes the pipe wall clean, edge to edge. Where a standard cable pokes through a clog, a flex shaft descales the line, removing hardened grease, mineral scale, and root fuzz that keeps a pipe clogging. It is a good middle ground between cabling and hydro jetting, especially in smaller lines and cast-iron pipe.
We choose flex shaft cleaning when a line is coated with buildup rather than blocked by a single obstruction, and when descaling will restore more capacity than a cable alone.
Signs you should call
- A line keeps clogging after standard cabling
- Old cast-iron pipe is heavily scaled
- Buildup coats the pipe wall on camera
- Flow is restricted along the whole line
- Grease has hardened inside the pipe
How the service call works
- Camera or assess the line to confirm buildup, not damage
- Select the right chain or blade head for the pipe
- Descale the pipe wall edge to edge
- Test the flow
- Recommend a maintenance interval if buildup is recurring
