Jetting vs snaking
Snaking punches through a clog to restore flow — quick and cheap, but it leaves the pipe walls coated. Hydro jetting blasts the full pipe diameter clean with high-pressure water, clearing grease, scale, and fine roots that snaking leaves behind. Jetting costs more and lasts longer; for a one-off soft clog, snaking is often enough.
Scope before you jet
High pressure can crack a pipe that’s already fragile — old clay, Orangeburg, or corroded cast iron. A camera inspection first confirms the line can take it and locates what’s actually blocking flow. Reputable plumbers scope before they jet, not after.
When a repeat clog means more
Jetting is maintenance, not a fix. If the blockage was tree roots or a structural defect, it will return — and a clog that keeps coming back is a signal to consider lining or a replacement rather than jetting on a schedule forever. Watch for the other signs of a failing line.
Common questions
How much does hydro jetting cost?
Hydro jetting a residential sewer line typically runs $300–$900, averaging around $500. Emergency calls, heavy root masses, or long/deep lines push it toward the high end; a straightforward grease or soft-blockage clear sits at the low end.
What is the difference between hydro jetting and snaking?
Snaking (rodding) punches a hole through a clog mechanically for $150–$500 — fast relief, but it leaves buildup on the pipe walls. Hydro jetting uses high-pressure water (up to ~4,000 psi) to scour the full pipe diameter clean, including grease and roots. Jetting costs more but lasts longer.
Is hydro jetting safe for old pipes?
Not always. High-pressure water can damage pipes already cracked, corroded, or fragile (old clay or Orangeburg). A camera inspection first confirms the pipe can take the pressure — reputable plumbers scope before they jet.
How often does a clog come back after jetting?
A clean line stays clear for a long time, but if roots or a structural defect caused the blockage, they will return — jetting is maintenance, not a repair. A clog that keeps recurring is a sign to camera the line and consider lining or replacement.
