The selection of the attachment for a sewer snake is also important. The choice of attachments for a sewer drain snake is generally limited to:
-
- cutting blade
- grease bulb
- hook
- drophead
If the technician is confident that a full-size blade can be passed through the pipe on the first attempt, a blade the same size of the pipe may be selected. Discretion, however, usually dictates the use of a smaller size blade to open the pipe and get water flowing, then insert a full-size blade to clean the pipe down to the sides.
