drain-cleaning methods
Cable, Rooter, Chain Knocker, or Camera?
Tool choice depends on line size, access, material, obstruction, and the result the customer needs.
Understand why one tool is not the correct answer for every clog or pipe material.
Cabling opens a path
A cable and appropriate head can break through or retrieve many common restrictions so flow can resume.
Rooter work addresses mainlines
Mainline equipment is selected for larger building-sewer restrictions and requires suitable access.
Chain knocking cleans pipe walls
A chain knocker can remove stubborn roots, scale, or buildup more broadly when pipe condition permits.
Camera work verifies condition
Inspection does not itself clear a clog, but it can document remaining material, damage, or the reason a blockage returned.
Questions specific to this resource
drain-cleaning methods FAQ
Is the largest machine always best?
No. Equipment must fit the line, access, material, and obstruction to avoid ineffective or inappropriate work.
Can cleaning damage old pipe?
Pipe condition affects method selection. Existing fragility, deformation, or collapse must be considered before aggressive cleaning.
How do I know the line is clear?
Restored flow is the immediate test; camera verification can add evidence when recurrence or damage is a concern.
