Use drain snaking to punch through a single, localized clog quickly. Use hydro jetting when you have recurring backups, grease buildup, scale, or roots, because a jetter scours the full pipe wall instead of just opening a hole through the blockage. For restaurants and older buildings, jetting is usually the better long-term fix, but the pipe should be camera-inspected first to confirm it can handle the pressure.
Drain snaking, also called cabling or rodding, feeds a rotating steel cable into the line to break through or grab a blockage. It is a targeted, low-force approach that opens a path through the clog, but it tends to leave grease and buildup on the pipe walls.
Hydro jetting sends water through a specialized nozzle at high pressure, both cutting the blockage and scouring the entire inside diameter of the pipe. Commercial jetters commonly run up to around 4,000 PSI. The rule of thumb from equipment makers is that PSI is the cutting power and GPM (gallons per minute) is the flushing power, so grease and roots need higher pressure while sand and sediment need higher flow.
| Factor | Drain Snaking | Hydro Jetting |
|---|---|---|
| Best for | Single, recent, localized clog | Recurring or widespread buildup |
| Grease & scale | Opens a hole, leaves wall coated | Scours grease and scale off the wall |
| Roots | Cuts with a root head, does not clean wall | Cuts roots and flushes debris out |
| Fragile old pipe | Gentler option | Camera-inspect first before jetting |
| Typical cost | Lower | Higher, but longer-lasting |
Reach for a cable machine when there is a single fixture backing up, the clog is recent and close to the drain, speed matters, or the pipe is old and fragile enough that high pressure is a risk. Snaking is also the tool for retrieving a foreign object. It is the more cost-effective choice for a minor, accessible blockage.
Jetting earns its cost when blockages keep coming back, when several fixtures gurgle or drain slowly at once, when a commercial kitchen has heavy grease in the lines, or when light roots have entered a main. It is also the next step when a snake has already failed against thick, viscous buildup. Because it removes grease, soap scum, scale, and roots from the whole pipe wall, it resets the line rather than just poking through it. This is why restaurant grease lines are a classic hydro jetting case.
High pressure is not safe on every pipe. Severely corroded cast iron, deteriorated galvanized branches, cracked clay with separated joints, and Orangeburg pipe can lose material or shift under a jetter. A camera inspection tells the technician whether the pipe is structurally sound, lets them set the right pressure and nozzle, and confirms whether cleaning is even the correct fix or whether the line needs repair or repiping instead.
As general industry guidance rather than a fixed rule, many restaurants jet grease lines every 6 to 12 months, high-volume kitchens with heavy fryer use every 3 to 6 months, and lighter kitchens about once a year. The right interval depends on your volume, how well the grease trap is maintained, and the condition of the lines, so the schedule is best set after an inspection of your specific system. Pairing a jetting schedule with on-time grease trap service is what actually stops the backups.

A hydro jetting job is more methodical than just blasting water down a pipe. First the plumber locates a cleanout and, on a commercial line, runs a camera to confirm the pipe can take the pressure and to find the trouble spots. A hose with a specialized nozzle is then fed into the line. The nozzle sends most of its jets backward at an angle, which does two things at once: it drives the hose forward through the blockage and scours the full inside wall of the pipe as it goes, flushing grease, scale, and debris back toward the cleanout. Pressure is matched to the line, commonly up to around 4,000 PSI for typical commercial pipe, and the flow rate in gallons per minute carries the loosened material away. A final camera pass confirms the wall is actually clean, not just punched through.
Snaking, also called cabling or rodding, feeds a flexible steel cable into the drain and spins it. A cutting or retrieval head on the end breaks through the clog or grabs and pulls it back. It is fast, low-force, and effective at reopening a line that a single object or a localized mass has plugged. What it does not do is clean the pipe wall. The cable bores a hole through the blockage and restores flow, but the grease, soap, and scale coating the pipe stay behind, which is why a snaked grease line so often backs up again within weeks. For the right problem, though, a cable machine is the faster and cheaper tool, and sometimes the safer one on fragile pipe.
For restaurants and any facility with heavy grease or high-volume drains, the smartest use of jetting is not the emergency call, it is the schedule that prevents it. A preventative program jets the kitchen and main lines on a set interval tuned to how fast they load up, so the pipe never reaches the point of a mid-service backup. That interval is set from experience with your specific system and from what the camera shows, not from a generic calendar. Pairing scheduled jetting with on-time grease trap service and rolling it into a maintenance agreement is how busy kitchens stop losing revenue to surprise closures.
A straightforward drain clearing is often a same-visit job. The plumber diagnoses the blockage, clears it by the appropriate method, and, for anything recurring, recommends a camera inspection to find the root cause rather than treating the symptom again. If the camera reveals a cracked, offset, or root-infiltrated pipe, cleaning alone will not hold, and the real fix is trenchless lining or a sewer line repair. Getting that diagnosis right the first time is what saves you from paying twice.
General information. PSI ranges and maintenance intervals are commonly cited guidance, not fixed standards; your plumber sets the right approach after inspecting the specific line.
