Hydro jetting vs. snaking: which does your drain need?

By the Alpha Drain teamPublished November 14, 20267 min read

Both tools clear drains. They do it in different ways, cost different amounts and suit different problems. Plenty of drains only ever need a cable. Some will not stay clear without jetting. A few should not get either until the pipe is repaired. Here is how to tell which is which.

What is the difference between snaking and hydro jetting?

A snake, also called a cable machine or drain auger, is a steel cable spun by a motor with a cutting head on the end. It is fed into the pipe until it reaches the blockage, then it bores through or hooks the material so water can pass. Machines are matched to the pipe. One common main line drum machine, for example, is built for 3 to 6 inch pipe and carries 100 feet of cable, with blades for roots and debris.

A hydro jetter uses water instead of steel. A pump sends water through a hose to a nozzle at high pressure. The hose is pushed down the line, and as it is pulled back the water scrubs the pipe wall and flushes the loosened material downstream. A portable jetter from the same manufacturer is rated at 3,000 psi and 5.5 gallons a minute and is made for 2 to 10 inch lines. Its maker describes the job as clearing sludge, soap, grease and sediment.

The short version: a snake opens a path through the clog, and a jetter cleans the pipe.

When is snaking the right choice?

A cable is the right tool more often than not. Reach for it when:

• One fixture is clogged: a tub full of hair, a toilet with too much paper, a sink with something lodged in it
• It is the first clog in years and there is no pattern behind it
• Something solid has to be hooked, broken up or pulled back
• Roots have closed a main line and it needs to flow today
• The pipe is old and nobody has looked inside it with a camera yet

Snaking has limits. In a line coated with grease, a cable can pass through and leave most of the buildup on the wall, where it closes up again. In a line with roots, cutting them does nothing about the gap they came through. A snake deals with the blockage in front of it. It tells you little about why the blockage formed. For a one-off clog that is fine, and standard drain cleaning is all you need.

When is hydro jetting the better choice?

Jetting earns its higher price when the problem is the pipe wall, not a single obstruction:

• Clogs keep coming back in the same line
• A kitchen line is slow from grease, soap and food residue
• A restaurant or commercial kitchen line carries grease every day
• A camera shows sludge or scale along the length of the pipe
• Roots have been cut and the line needs to be washed clean before a repair
• A line has to be cleaned so a camera can see the pipe itself

Hydro jetting has limits too. It needs a suitable way in, usually a cleanout. It uses more equipment and takes longer, so it costs more than a basic cable job. And high-pressure water is the wrong tool for pipe that is already broken, which is the reason for the next section.

Why should a camera inspection come first?

Neither tool can see. A cable tells the operator there is resistance 40 feet in. It cannot say whether that is a wad of wipes or a collapsed pipe. A sewer camera inspection answers the question before anyone picks a tool.

This matters most on older pipe. Some mid-century homes were built with a tar-impregnated fiber pipe sold as Orangeburg. One city utility that documents sewer pipe materials notes that when roots get into this pipe, a mechanical rooter tears out pieces of the pipe as it cleans, which leads to collapse. A pipe like that needs replacing, not more cleaning. The same goes for clay pipe with a broken section or cast iron that has rusted through along the bottom.

A camera also changes what you pay for. If it shows a clean pipe with one soft clog, a cable is all you need. If it shows grease coating the whole run, cabling alone is money spent twice. If it shows a break, you skip both and get a price for the sewer line repair.

After jetting, the camera should go back in to confirm the line is clean and to record its condition. That footage is your proof of what was done and your baseline for next time.

How do hydro jetting and snaking compare side by side?

Which one should you ask a plumber for?

Ask for a diagnosis instead of a tool. Describe the history: which fixtures, how often, and what has been tried. For a first clog at one fixture, expect a cable. For a line that has clogged again and again, expect a camera and a conversation about jetting or repair. Be wary of anyone who recommends the most expensive option without showing you the inside of the pipe.
