Mechanical cleaning means "punching through with a flexible snake." The snake can range from a 3-metre hand tool to a 25-metre motorised one. Seventy percent of apartment clogs are cleared with this alone — and it costs less than hydro jetting.
What mechanical cleaning is
- Hand snake of 3–5 m — a household tool, reaches the first bend past the trap.
- Professional drum snake of 8–15 m — a "gun" in the plumber's hand, the cable sits in a drum.
- Electric snake of 15–25 m — motorised, with a set of nozzles (spear, hook, brush, cutter).
The goal is to mechanically break the plug or push it further into a wider section, where the flow carries it away.
What nozzles are used
- Spear / pike — punches through dense clogs of rags and organic matter.
- Hook — catches hair plugs and pulls them back out.
- Brush — works like a scrubber, cleans soft deposits from the walls.
- Expanding cutter — cuts roots and hard buildup in wider pipes, used for external sewer.
When a snake is the best option
- One-off blockage in the bathroom, shower or kitchen — fast and cheap.
- A plug from a rag, a nappy or a foreign object in the toilet — hydro jetting will not push that out.
- A clog 5–15 m from the access point — the typical length of apartment pipe runs.
- Diagnosing "where it sits." From the length at which the snake stops, the plumber can estimate the clog location.
When a snake will not help
- A plug more than 20–25 m from the entry — the snake bends and does not reach.
- A grease clog in the kitchen: the snake makes a hole, but the walls stay sticky — it blocks again in a couple of weeks. Hydro jetting is needed.
- A pipe that is crumbling or sagging — the snake can get stuck or pierce through.
- Roots in the external sewer — require a special cutter or hydro jetting with a root cutter head.

At the end the plumber usually runs tap water through and does a "test pour" to confirm the drain flows freely without delay.
Frequently asked
A hand snake costs ILS 50 at the shop — why call a plumber?
For a small household clog, you can indeed handle it yourself. But the plumber has a longer snake with nozzles, and more importantly — experience: when the snake "drops in," it is not a win but a sign that it went into a side branch or got stuck on a joint. That takes reading.
The snake will not fit through the drain — what now?
Then the drain is too twisted (as in shower traps) or the trap has a restrictor. The plumber will remove the trap and feed the snake from the other side. You can do this at home too, but carefully — do not crank pipe nuts with a dry wrench if the trap is plastic.
After using the snake I noticed leaks at the joints — why?
Plastic traps and flex hoses "age" over the years, and gaskets dry out. While dismantling, the plumber usually replaces the seal or suggests a new trap (ILS 200–350). If you notice a leak yourself, do not delay — otherwise it will flow under the kitchen cabinet.
Can the plumber use only a snake without pushing hydro jetting?
Yes, and it is normal: a good plumber does the minimum necessary first. If the snake solves the problem, hydro jetting is not needed. It is only suggested when the clog returns or grease is visible along the whole length.
