Snaking vs Hydro-Jetting: Which Does Your Sewer Line Need?

Reviewed by Tyler Bennett, Restoration Project Manager, IICRC WRT/ASD #291438, October 2026.

Short answer: Snaking (augering) pushes a rotating cable through the line to cut a path through a clog or roots. Hydro-jetting uses high-pressure water to scour the full inside of the pipe, removing grease, sludge and root fragments. Snaking is a good first response to a simple clog; hydro-jetting is better for grease buildup and repeat clogs. A camera inspection tells you which one your line needs.

How snaking works

A motorized cable with a cutting head is fed into the line from a cleanout. It breaks up the blockage or cuts through roots so water can flow again. It is fast and works well on a single clog, like wipes or a small root intrusion. What it does not do is clean the pipe walls, so grease and root remnants stay behind.

How hydro-jetting works

A hose with a nozzle sprays water at high pressure forward and backward through the line. It cuts through the blockage and scours grease, scale and debris off the inside of the pipe, so the line is cleaned close to its full diameter. It is the better choice for kitchen grease, sludge and lines that keep clogging.

Which one your line needs

• One-time clog from wipes or paper: snaking is usually enough.
• Grease buildup from the kitchen line: hydro-jetting.
• Repeat clogs every few months: hydro-jetting, plus a camera inspection to find out why.
• Roots: snaking or jetting clears them; if the camera shows a cracked or separated joint, a repair is the lasting fix.
• Broken or collapsed section: neither will fix it; the section needs repair or replacement.

Why we often start with a camera

Clearing a line without seeing it is a guess. A camera inspection shows whether the problem is a clog, grease, roots, a sag where waste collects, or a broken pipe. That decides whether snaking, jetting or a repair is the right job, and it gives you a record of the line’s condition.

What to do while you wait for us

1. Stop using water: no flushing, showers, laundry or dishwasher.
2. Keep people and pets away from any sewage that came up.
3. Do not pour chemical drain openers into a backed-up sewer line; they rarely reach the blockage and make the water hazardous to work in.
4. Photograph any water or sewage that reached the floor for your insurance carrier.
5. If you know where the cleanout is, make sure we can get to it.

Signs a simple clear will not be enough

• The same clog returns within weeks or months
• Several fixtures back up at once, not just one drain
• Sewage smell in the yard or wet spots over the line
• Clearing brings back pieces of pipe, soil or heavy root mass

Those point to a problem in the line itself. A camera inspection shows whether it needs a repair.

Common questions

Is hydro-jetting safe for old pipes?

It depends on the pipe’s condition. A camera inspection first shows whether the line is sound enough for jetting or whether a damaged section should be repaired instead.

Will snaking get rid of tree roots for good?

No. Snaking cuts roots so the line flows again, but roots that entered through a joint or crack usually grow back. Hydro-jetting clears more thoroughly; a repair is the long-term fix when the line is damaged.

Which one is cheaper?

Snaking is usually the simpler job, but the cheaper option is the one that fixes the problem the first time. 4Sure gives a free written estimate after seeing what is in the line.

Do you do both?

Yes. 4Sure does snaking, hydro-jetting, camera inspection and repair of damaged sections, and handles the sewage cleanup if the backup reached the house.
