If you have Googled “what is hydro jetting” or “hydro jetting vs snaking,” odds are a drain keeps clogging and you want to know if the more expensive method is actually worth it. Short answer: sometimes yes, sometimes no — and any plumber who tells you otherwise is guessing. Below is the honest breakdown from a Registered Master Plumber who runs a jetting truck every week in Bucks & Montgomery County, PA.
What Is Hydro Jetting?
Hydro jetting — also called sewer jetting or water jetting — is a drain cleaning method that pushes water through a specialized hose and nozzle at very high pressure, typically 1,500 to 4,000 PSI. The nozzle uses reverse-thrust jets to pull itself down the pipe while forward jets cut through the blockage. The pressurized water scrubs the full inside wall of the pipe clean and flushes grease, roots, scale, and debris back to the cleanout.
Think of it as a pressure washer for the inside of your sewer line. Done right, jetting restores the pipe to its original diameter — not just a channel down the middle.
What Is Snaking (Cabling)?
A drain snake — also called a cable, auger, or rooter — is a flexible metal cable with a cutting head on the end. A motor spins the cable through the line and the cutting head chews a hole through the clog. Snaking is the workhorse of drain cleaning: fast, cheap, and effective when the problem is a single hard blockage.
Hydro Jetting vs Snaking — Side by Side
| Factor | Snaking / Cabling | Hydro Jetting |
|---|---|---|
| How it works | Cable with cutter punches a hole through the clog | High-pressure water scours the full pipe wall |
| Best for | Single hard clog, hair, small root intrusion | Grease, scale, recurring clogs, root systems, restaurants |
| Removes build-up on pipe wall | No — leaves a coated pipe | Yes — restores full diameter |
| Cost | Lower up front | Higher up front, cheaper long-term |
| Clog comes back? | Often within weeks/months if build-up is the cause | Usually solved for 18–24+ months |
| Camera included | Rarely | Yes — before & after at Angermeier |
When to Snake Instead of Jet
- First-time clog, no history of recurring backups
- Bathroom sink, tub, or toilet line with a hair/paper clog
- You need it opened right now and cost is the priority
- Simple kitchen line with a fresh blockage (not decades of grease)
When to Choose Hydro Jetting
- Main sewer line clog — especially recurring ones
- Kitchen line clogging every few months (grease glaze)
- Cast iron lines with mineral scale narrowing the pipe
- Tree roots visible on a camera scope
- Restaurants, salons, laundromats, multi-family properties
- New homeowner with no history of the sewer lateral
- You want it fixed once, not four times a year
This is why our slogan is “Jet it and forget it.” Cabling drills a hole through the clog. Jetting removes the reason the clog formed.
Is Hydro Jetting Safe?
In healthy PVC, cast iron, and clay lines — yes. PSI and nozzle are matched to the pipe. Where it is not safe is a line that has already failed structurally: cracked joints, collapsed sections, or old Orangeburg (tar paper) pipe. That is why every one of our jetting jobs starts with a camera inspection. If we find a defect, we show you the video and quote a repair — we do not jet a pipe that is already broken.
The Bottom Line
Snake it when the problem is a single, one-off blockage. Jet it when the pipe itself is the problem — grease coated, root-invaded, scale-narrowed, or clogging over and over. If you are not sure which one you need, we camera the line first and tell you honestly. A $0 diagnosis beats a $400 guess.

Frequently Asked Questions
What is hydro jetting?+
Hydro jetting (also called sewer jetting or water jetting) is a drain cleaning method that uses a specialized hose and nozzle to blast water through a sewer or drain line at high pressure — typically 1,500 to 4,000 PSI. The water scours grease, roots, scale, and debris off the full inside wall of the pipe and flushes it back to the cleanout, restoring the line to full diameter.
What is the difference between hydro jetting and snaking?+
A drain snake (or auger/cable) is a flexible metal cable with a cutting head that spins through the clog and punches a hole through it. Hydro jetting uses pressurized water that scrubs the entire pipe wall clean instead of just clearing a channel through the middle of the blockage. Snaking is faster and cheaper for a single hard clog; jetting removes the underlying build-up so the clog does not come back in a few months.
How much does hydro jetting cost?+
Residential hydro jetting in Bucks and Montgomery County, PA is typically a flat rate that includes a before-and-after camera inspection. Cost varies with line length, access, and severity — call 215-364-0133 for an upfront quote. Because jetting solves the underlying problem, it is usually cheaper long-term than repeat snaking calls.
Is hydro jetting safe for old pipes?+
In most healthy cast iron, PVC, and clay lines yes — jetter PSI and nozzle selection are matched to the pipe. We camera every line first. If a pipe is cracked, collapsed, or Orangeburg, we flag it before jetting and recommend spot repair or replacement instead. Jetting is not the right call for a pipe that has already failed structurally.
How often should I hydro jet my main sewer line?+
For a typical single-family home with no history of problems, every 18–24 months as preventative maintenance is plenty. Homes with mature trees over the lateral, restaurants and salons with heavy grease or hair, and multi-family properties often benefit from annual jetting.
Can hydro jetting cut tree roots?+
Yes. A root-cutting nozzle uses reverse-thrust jets to chop through fine and medium root intrusions and flush the debris back to the cleanout. For a fully root-choked line or a broken pipe joint letting roots back in every year, a spot repair or lateral replacement is the permanent fix.
