"Just snake it" is the most common request we get on drain calls — and the most common reason we're back at the same house six months later. Snaking and hydro-jetting solve different problems. Here's how to know which one your situation needs.
What each tool actually does
Drain snake (auger)
A flexible metal cable with a cutting tip. Spins through the drain, breaks up or hooks into a single blockage, pulls it back out. Reaches 25–100 feet depending on the machine. Punches a hole through the clog so water can flow again.
Hydro-jet
A pressurized water nozzle (3,000–4,000 PSI) on a high-pressure hose. Cleans the entire inner wall of the pipe by force, removing grease coatings, soap scum, hair, mineral deposits, and root intrusion. Reaches 200+ feet. Restores pipes to near-original diameter.
The decision tree
Use this in order. If you answer yes at any step, that's your call.
- Is this the first time this drain has clogged in 12+ months? → Snake will probably fix it.
- Is the clog a single object you can identify? (kid's toy, paper towels, hair ball) → Snake.
- Is it the kitchen sink, and you cook a lot of bacon / oil / fried food? → Hydro-jet. Snaking grease just punches a tunnel through it; the walls are still coated.
- Is it the main sewer line, with mature trees in the yard? → Hydro-jet. Roots cause re-clogs in 60–90 days after snaking. Jetting cuts and flushes them out.
- Has this drain backed up 2+ times in the last year? → Hydro-jet. The walls are coated and you've been treating symptoms, not the cause.
- Are you smelling sewer gas or seeing slow drains in multiple fixtures simultaneously? → Hydro-jet on the main line. You have a partially-collapsed or heavily-coated main.
Cost comparison (NJ averages)
| Service | Cost range | Typical duration | Re-clog risk |
|---|---|---|---|
| Snake (single drain) | $149–249 | 20–45 min | 30–50% within 6 months for grease/root issues |
| Snake (main sewer) | $249–399 | 45–90 min | 40–70% within 12 months if roots present |
| Hydro-jet (single drain) | $349–549 | 45–90 min | <5% within 12 months |
| Hydro-jet (main sewer) | $549–899 | 90 min–3 hr | <10% within 24 months |
| Camera inspection | $149–249 | 30 min | (diagnostic only — included with most jet jobs) |
Why a "$99 drain cleaning" coupon is almost always a trap
You've seen the ads. Here's what's actually happening: the company sends a tech with a small electric snake, runs it 25 feet, hits the closest blockage, calls it done. The clog two feet past where they reached re-blocks within weeks. Then on the second call, suddenly there's "an emergency" and "this needs jetting" — for $700.
If your drain is more than a one-time hairball, paying $99 + $700 is worse than paying $549 once. We know because customers tell us this story every week.
The case for camera inspection
For mainline issues — anything past your sink trap and into the wall or below the foundation — a camera inspection before you commit to a fix is almost always worth it. Here's what a camera tells you that nothing else can:
- Whether the pipe itself is broken, collapsed, or just clogged.
- Where exactly the problem is — to the inch.
- What pipe material you have (cast iron, clay, PVC, Orangeburg) — which determines whether jetting is even safe.
- If there are root intrusions, how extensive they are.
- Can I rent a hydro-jet from Home Depot?
- You can rent small electric jetters (1,500 PSI), but they won't touch grease coating or root intrusion — those need 3,000+ PSI. The rental machines are for clearing slow drains, not problem mains.
- Are drain chemicals (Drano, Liquid Plumr) safe to use first?
- For a one-time slow drain — sure, occasionally. Long term they corrode pipes, especially older galvanized steel and PVC joints. We've replaced enough $400 sink traps to recommend you skip them.
- Will jetting damage my old pipes?
- Not if the tech runs a camera first and adjusts pressure for pipe condition. We jet 1920s cast iron and 1970s PVC every week — but always with eyes on what we're working with. Refuse any tech who won't camera before jetting an old line.
- How often should main sewer lines be cleaned?
- If you have mature trees and the original cast-iron main, every 18–24 months as preventive. Modern PVC mains with no nearby root sources can go 5+ years between cleanings.
