A jetting nozzle directs water inside the pipe. Some designs emphasize rearward jets to move through a line and carry debris back. Others direct water ahead or around the pipe wall. The choice depends on the condition of the pipe and what needs to be removed.
Match the nozzle to the material
Loose sediment and grease can call for different approaches. Tell the plumber whether previous work found roots, scale, or a damaged joint. Pipe diameter, bends and access can also limit which tools can pass safely.
Ask how the result will be checked
The technician should be able to explain which section was reached and how flow or pipe condition was checked afterward. If a fitting or damaged section prevents access, ask how that affects the scope before approving additional work.
