A drain auger — also called a drain snake — is one of the most practical tools a homeowner, holiday-rental operator, or hotel manager can keep on hand. When a plunger fails and chemical drain cleaners do nothing, feeding a flexible steel cable into the pipe is usually what finally breaks the clog free. The video above shows Richard Trethewey of This Old House doing exactly that; the steps below translate the technique into a clear sequence you can follow in any Greek home, villa, or apartment.
What a drain auger is — and when to reach for one
A drain auger is a coiled steel cable wound inside a drum or canister. You feed the cable into the drain by hand or with a powered drum, rotating it as it travels through the pipe. The rotating tip either breaks up the clog or hooks into it so you can pull the debris back out.
Augers come in two main forms: hand (manual) drum augers, which are ideal for bathroom sinks, showers, and bathtubs; and electric or battery-powered models, which are better suited to kitchen lines, floor drains, and longer runs. For most domestic clogs in a standard Greek apartment or villa bathroom, a 6–10 mm cable on a 7.5-metre manual drum is all you need.
Safety, limits, and when to call a licensed plumber
A drain auger is safe for the pipes and the person using it, provided you follow basic precautions: wear rubber gloves, protect your eyes from splash-back, and never force a cable that meets solid resistance without rotating it — forcing it straight can score the inside of older ceramic or cast-iron pipes. Avoid using an auger in pipes that show signs of collapse, significant corrosion, or that have already been chemically treated with lye-based cleaners (the residue can splash back and cause burns).
Some blockages are beyond a DIY auger. Tree-root intrusion into the main sewer line, a collapsed pipe, or persistent sewer-gas smell after clearing a clog all require a licensed plumber — who may use a CCTV pipe camera, a high-pressure jetter, or excavation. In Greece, mains drainage connections and communal building stack repairs must be carried out by a registered plumber (υδραυλικός). When in doubt, stop and call a professional rather than risk damaging shared infrastructure.
How to use a manual drum auger: step by step
- 1
Prepare the drain and protect the area
Put on rubber gloves and lay old towels or a plastic sheet on the floor around the drain. Remove the drain cover or stopper — most bathroom pop-up stoppers unscrew or lift off a centre pivot rod. Place a bucket nearby to receive the cable and any debris you pull out. If the blockage is under a sink, clear out the cabinet below and position the bucket under the P-trap in case you need to remove it.

Set the cable length and insert the auger tip
Loosen the thumbscrew or locking collar on the drum so the cable can feed freely. Guide the auger tip (the corkscrew or bulb end) into the drain opening. Feed about 20–30 cm of cable into the pipe by hand before tightening the locking collar again. Keep the drum close to the drain — the shorter the exposed cable, the more control you have and the less the cable will kink or whip.
- 3
Rotate and advance through the pipe
Turn the drum handle clockwise while applying gentle forward pressure. The cable will travel through bends in the pipe; if it stops moving, ease back a little, then advance again — sharp 90-degree bends in Greek plumbing (common in older buildings) require patience. When you feel the tip hit the clog, keep rotating. The rotation is what does the work: it either breaks the blockage apart or winds the cable into it so you can extract it.
- 4
Clear or retrieve the clog
Once the cable is engaged in the blockage, pull back slowly while continuing to rotate clockwise. Hair mats, soap-scum plugs, and food debris will ride out on the tip. Pull the cable all the way out over the bucket — never drop it directly on the floor — and wipe it clean with disposable rags as it comes out. If the obstruction did not come out intact, run the auger through two or three more times and then flush with hot water to confirm the line is clear.

Flush, reassemble, and test
Refit the drain stopper or cover. Run the hot tap for at least two minutes at full flow while watching the drain. The water should clear the basin quickly with no gurgling. A slow drain after augering often means some debris remains or there is a partial blockage further down the line — repeat the process or, if a second attempt does not resolve it, call a plumber. Once satisfied, rinse the auger cable, dry it, and apply a light coat of machine oil before storing to prevent rust.

FAQ
- Can I use a drain auger on every type of drain in my home?
- A standard hand drum auger works well on bathroom sinks, showers, bathtubs, and laundry tubs. For kitchen sinks with a grease build-up, a longer cable (15 m) or an electric model is more effective. Do not use a light-duty auger on a main sewer clean-out or a toilet — toilets have a built-in trap that requires a dedicated closet auger (toilet snake) to avoid scratching the porcelain bowl.
- How do I know when the clog is cleared rather than just pushed further down?
- The clearest sign is that water drains at full speed with no gurgling after you remove the auger and run the tap. Gurgling after clearing usually means air is trapped because a partial clog still exists downstream, or the vent stack is blocked. If the drain runs clear for a few days and then slows again, the clog was not fully removed — a second, deeper pass with a longer cable or professional jetting is the next step.
- Is a drain auger safe for the older pipes found in Greek buildings?
- Most pre-1990 buildings in Greece use cast iron or thick PVC for vertical stacks and thinner PVC or copper for branch lines. A manual auger with a 6 mm cable is gentle enough for all of these when used correctly — always rotate clockwise and never force the cable. Avoid using electric augers with large (10 mm+) cables on thin PVC branch lines, as the torque can crack the pipe at joints. If your building is very old and you suspect corroded cast-iron pipes, have a plumber inspect first.
