VMS stocks a full range of parts for all drain cleaning equipment and all in stock items ship the same day.  The drain cleaning cable itself is actually a tightly coiled, flexible wire spring that rotates in the pipe and, when it connects with a blockage, forms into a stiff rod that rams through the debris. We stock cables from 1/4" to 3/4" in diameter and in lengths from 25’ to 100’. 
The drain snake may have an attachment on its end. The attachments are designed to cut and clear whatever is blocking the sewer pipe. Attachments include blades of various shapes and edges, hooks for retrieval of debris, cutters, augers and drop heads that navigate bends in the pipe.
VMS stocks sewer machine parts to fit; General Wire, Rigid, Marco, Spartan, Electric Eel and others.
