Types of Drain Snakes: Which One Fits Your Clog

Plumbing Picks is reader-supported. As an Amazon Associate, we earn from qualifying purchases at no extra cost to you.

Quick answer from a licensed plumber: There are eight types, and the fixture and the pipe size pick the type. A barbed plastic strip clears hair from a bathroom sink or shower. A 1/4 in. drum auger, by hand or with a battery drill, handles a sink, tub or shower line up to 1-1/2 in. per RIDGID. Most showers are 2 in., so check the pipe first. A toilet takes a closet auger only, because several makers warn against putting a regular cable in a toilet. Bigger lines, roots and main lines are machine or pro work.

Our pick for a first snake on a sink, tub or shower line up to 1-1/2 in.: the RIDGID POWER SPIN+. Check the RIDGID POWER SPIN+ on Amazon

“Drain snake” (also sold as a plumbing snake or drain auger) covers eight different tools, and they are not interchangeable. The tool that clears a shower hair mat will not clear a toilet, and the tool that clears a toilet will not reach a main line. Two facts pick the type: which fixture is clogged, and how big the pipe is. Most makers give a cable size and a pipe range for their tools. This page puts them side by side, then points you to the guide that picks the model. For a ranked roundup of home snakes, see our best drain snake for home use guide.

The Eight Types of Plumbing Snakes at a Glance

Cable sizes, lengths and pipe ranges below are what each maker publishes. Where a maker’s page and manual disagree, the table says so and we go by the manual.

Several RIDGID ranges conflict, and it matters. The POWER SPIN+ manual says 3/4 to 1-1/2 in. and not to use it in larger lines, while RIDGID’s catalog and product page say up to 2 in. The PowerClear does the same: 1-1/2 in. in the manual, 2 in. in the catalog. The K-25 spinner has three ranges: 2 in. in the 2025 catalog, 2-1/2 in. on its web page beside a 40 mm figure, and 1-1/2 in. in an older catalog. The 40 mm figure is 1-1/2 in., so we use 1-1/2 in. The K-400 says 3 to 4 in. for its 1/2 in. cable in the manual, and 2 to 4 in. in the catalog. Cobra’s 110ES manual says 1-1/4 to 3 in., while its web page says 3/4 to 3 in. When a range conflicts, go by the manual and use the narrower number.

Match the Cable to the Pipe

Every maker warns about size. RIDGID and Milwaukee both say that using the wrong size drain cleaner can twist, kink or break the cable and cause injury, and Milwaukee adds that a cable should not go in larger pipes than its chart lists. The clearest cable-to-pipe chart comes from General Pipe Cleaners, which prints it for its Flexicore cables. The Milwaukee charts are close on the small sizes: 1/4 in. cable for 1-1/4 to 2 in. lines, 5/16 in. for 1-1/4 to 2-1/2 in., and 3/8 in. for 2 to 3 in. on the M18.

The 1/4 in. and 5/16 in. rows match the hand and drill snakes above. The rows from 3/8 in. up are machine cables. General marks the 1/2 in. and 9/16 in. cables “not for roots.” It lists 5/8 in. and 3/4 in. cables for main lines and roots, and pairs them with its large drum machines.

Which Fixture Gets Which Snake

Why a toilet needs its own tool

Three makers put it in writing. RIDGID says its POWER SPIN+ is not recommended for toilets, and its K-400 manual says not to feed the cable through a fixture because it could damage the drain cleaner and the fixture. Cobra’s Power Snake page says not for use with toilets. Cobra’s toilet augers add a rubber bowl guard and a polymer guide tube to help protect the porcelain during insertion. Milwaukee’s TRAPSNAKE manual warns that the boot must be in the drain to support the cable from whipping and that the cable can damage porcelain. The boot on a closet auger is there for that reason. Use a closet auger and read toilet auger vs drain snake for the difference.

Our Picks by Type

These are the types most homes need. The flat tape, drum and sectional rows are trade tools, so we do not link them; see our drain cleaning machine guide if you are in that territory. Each item below was in stock and sold by Amazon (or its maker) on September 29, 2026.

Safety Rules From the Manuals

Each rule in this list is from a maker’s manual or label, named beside it, and the makers do not all say the same thing. Read the manual for your tool.

• Gloves. RIDGID (POWER SPIN+ and PowerClear): wear leather work gloves, with latex or rubber gloves underneath. Milwaukee: leather gloves over latex or rubber. RIDGID (K-400): only RIDGID drain cleaning gloves or mitts, and never grasp the rotating cable with anything else, including a glove or a rag. RIDGID and Milwaukee also call for eye protection with their powered tools.
• Do not let the cutter stop turning while the cable spins. RIDGID and Milwaukee: this can overstress the cable and cause twisting, kinking or breaking. RIDGID lists striking and crushing injuries. One person must control both the cable and the switch, so you can turn the machine off.
• Reverse. RIDGID K-400: do not run in reverse except as described; it can damage the cable and is used to back the tool out of a blockage. Milwaukee: extended reverse can damage the cable and accessories. Cobra 110ES: reverse only if the cable is caught, and only for a few seconds. RIDGID POWER SPIN+: use reverse only if the cable is caught or to retract it.
• Whipping and distance. Milwaukee: start with the cable fully retracted to prevent whipping, and keep the tool no more than six inches from the drain opening. RIDGID K-400: within two feet of the drain inlet, or support the exposed cable; RIDGID PowerClear: the AUTOFEED unit within 6 in. of the inlet. Cobra 110ES: never fully retract a cable while it is rotating. RIDGID POWER SPIN+: keep the tool within 4 in. of the drain opening, and push at least one foot of cable into the drain before it starts turning so the cable does not come out and whip around.
• Drills. RIDGID POWER SPIN+: use a battery drill, never a corded one, and confirm it turns at less than 500 rpm.
• Do not force the cable. RIDGID POWER SPIN+: if the cable stops turning, it is not cleaning the drain; if it sticks, do not keep turning the drum.
• Chemicals in the drain. RIDGID and Milwaukee: find out whether drain cleaning chemicals are present, and contact the chemical maker for the safety steps before working around them. Drano’s label: never use a plunger during or after use because Drano may still be present. Wear latex or rubber gloves and goggles when chemicals or bacteria are suspected, and wash your hands afterward with hot, soapy water.
• Water and power. RIDGID: do not run the machine while you or it are standing in water, and only use extension cords protected by a GFCI (K-400 manual).

The manuals do not use the word “kickback.” They describe the same hazard as the cable twisting, kinking, breaking or whipping. Our take as a plumber: a hand strip, hand auger or closet auger is a low-risk tool. Any spinning cable, especially on a drill or a machine, deserves the full glove and eye protection routine above.

When to Stop and Call a Pro

A snake is for one fixture. Stop and call a plumber in these cases:

• More than one fixture is backing up. That points to the main line, not a branch. See clogged drain or main line and why a main drain keeps clogging. No hand snake is the tool for that.
• Roots. RIDGID says the K-400 is not designed to remove root blockages, and General marks its 1/2 in. and 9/16 in. cables not for roots. Root cutting is done with 5/8 in. and 3/4 in. cable on a heavy machine, per General.
• The clog is past where your cable reaches. Compare your cable to the maximum distance in the chart above. A 25 ft. hand snake will not reach a clog 40 ft. down a line.
• The cable binds and will not back out. Do not force it. RIDGID says a stuck cable can twist and kink if you keep turning the drum.
• You already poured a chemical opener and water is standing. Drano says no plunger. RIDGID and Milwaukee say to get the chemical maker’s safety steps first. Our advice is to have a pro handle it.
• You do not know what is in the line. A drain or sewer camera shows it. See the best sewer camera with a locator, and what unclogging a main drain costs before you choose between renting a machine and hiring the job out.

A snake also does not prevent the next clog. If a drain keeps slowing down, see hair catchers for showers, and the enzyme drain cleaner guide for upkeep. Enzymes are not a snake; the guide reads what the labels say.

Before You Buy

1. Name the fixture. Toilet means a closet auger. Everything else starts at the bathroom strip or a 1/4 in. drum auger.
2. Find your pipe size. A drum auger that lists 3/4 to 1-1/2 in. is not for a 2 in. shower line. See shower drain size.
3. Check the maker’s pipe range and your cable length against the clog. A hand snake stops at its cable length.
4. Buy gloves and eye protection with the tool. RIDGID and Milwaukee call for both with anything that spins.
5. Decide what you will not do. No toilet with a drum cable, no roots, no main line with a hand tool.

FAQ

What are the different types of drain snakes?

Eight are worth knowing. A barbed plastic strip works on hair in a bathroom drain. A hand-crank drum auger and a drill-powered snake carry 15 to 50 ft. of 1/4 to 1/2 in. cable; the common home size is 1/4 in. x 25 ft. for sinks and tubs. A closet auger is the toilet tool. Flat tape is a flat steel ribbon sold by width and pipe capacity. A sink machine is a small powered drum. A drum machine and a sectional machine are bigger powered machines for larger lines. The table above gives each maker’s cable size and pipe range.

Can I use a regular drain snake in a toilet?

The makers say no. RIDGID’s POWER SPIN+ manual says it is not recommended for toilets, its K-400 manual says not to feed the cable through a fixture, and Cobra’s Power Snake page says not for use with toilets. Milwaukee’s toilet auger manual says the cable can damage porcelain and the boot must be in the drain. Use a closet auger.

What size drain snake do I need?

Match the cable to the pipe, per the makers. General’s chart lists 1/4 in. cable for 1-1/4 to 2 in. lines, 5/16 in. for 1-1/2 to 2 in., 3/8 in. for 2 to 3 in., and 1/2 in. for 3 to 4 in., not for roots. Milwaukee’s chart is close: 1/4 in. for 1-1/4 to 2 in. and 5/16 in. for 1-1/4 to 2-1/2 in. RIDGID’s POWER SPIN+ manual is tighter at 3/4 to 1-1/2 in. Bigger lines and roots are machine work.

Is a drain auger the same as a drain snake?

In practice the names overlap. Klein calls its strip a drain snake auger, Cobra sells drain augers and power snakes, and RIDGID files hand spinners, toilet augers and sewer tape under drain cleaning hand tools. The useful split is by fixture and pipe size, not by name: a closet auger for toilets, a strip or a drum auger for sinks, tubs and showers, and a machine for larger lines.

Do I need gloves to use a drain snake?

Yes for anything that spins. RIDGID’s POWER SPIN+ manual says to wear leather work gloves with latex or rubber gloves underneath. Milwaukee says leather gloves over latex or rubber. RIDGID’s K-400 manual goes further: only RIDGID drain cleaning gloves, and never grasp the rotating cable with anything else, including a rag. Wear eye protection with all of them.

Bottom Line

Name the fixture, find the pipe size, then pick the type. Use a strip for hair, a 1/4 in. drum auger for a sink, tub or shower line up to 1-1/2 in., and a closet auger for every toilet. Wear gloves and eye protection with anything that spins, never force a cable, and hand off roots, long runs and main lines.
