High-Velocity Hydro-Scouring.

Not when correctly specified. Professional jetting with appropriate pressure for the pipe material is safe for all sound pipe — cast iron, HDPE, PVC, modern clay. Where it needs caution: badly corroded cast iron with wall thinning, orangeburg (which can be weakened by high-pressure water), and already-collapsed sections. In those cases we camera-inspect first, and if jetting isn't appropriate we recommend CIPP lining or trenchless replacement instead.

Depends on menu and volume. Full-service kitchens doing 100+ covers at dinner typically need monthly jetting. Mid-volume operations are fine on a quarterly schedule. Low-grease menus (coffee shops, bakeries, counter-service operations) can often go semi-annual. If your line backs up between scheduled jettings, we increase frequency. If you go 18 months without buildup, we decrease it. The right cadence is the one that prevents emergencies without over-servicing.

Snaking uses a mechanical cutter on a cable to punch through or cut up blockages — fast, effective for isolated clogs, but doesn't clean the full pipe interior. Jetting uses high-pressure water to scour the entire circumference of the pipe — slower per foot, more expensive per visit, but removes buildup snaking leaves behind. For an occasional clog, snake. For recurring buildup, grease issues, or restoring pipe interior condition, jet.

Yes, and we do it regularly. Residential jetting uses lower pressure than commercial work (usually 1,500–2,500 PSI rather than 4,000) and we always camera-inspect first to verify the host pipe is sound enough for jetting. If the line is mostly healthy but has buildup we can't remove with snaking, jetting is often the right answer. If the line has structural problems, we switch to CIPP or trenchless replacement instead.
