The pipe must support the cleaning method
Camera review may be recommended before jetting an older or questionable pipe. Heavy grease, sludge, mineral scale, roots, and large-diameter lines can require different nozzles, pressures, flow rates, and working time.
- Residential versus commercial pipe
- Severity and type of buildup
- Cleanout and truck access
- Pre- and post-service camera passes
Define the intended result
Some work is intended to open a blockage; other work is intended to scour buildup across a longer section. The quote should identify the line covered, setup assumptions, debris handling, inspection, and what happens if a structural defect limits the cleaning.
