Blocked Drain Plumber in Paris

A blocked drain is one of the most common reasons people call a plumber in Paris — and one of the most miserable to live with. The sink fills up, the shower tray won't empty, a sour smell drifts up from the plughole, or worst of all, waste water starts backing up into the flat. The good news is that most blockages are straightforward for a plumber to clear. Call us and an English-speaking plumber will get your drain (canalisation) running freely again.

Signs your drain is blocked

A blockage rarely arrives all at once. It usually builds up over weeks and gives you warning signs first. Catching it early means a quick, cheap clear instead of a flood. Watch for:

• A slow-draining sink or shower. Water that pools and takes far longer than usual to disappear is the earliest sign that the waste pipe is narrowing.
• Gurgling sounds. A glug or gurgle from the plughole or toilet when water drains nearby means trapped air struggling past a partial blockage.
• A bad smell. A drain, eggy or sewage-like odour rising from a plughole points to rotting waste stuck in the pipe or a dried-out trap.
• Water backing up. Dirty water rising into the sink, shower tray or bath — especially when you use another fixture — means the blockage is now serious and needs a plumber.

Common causes in Paris flats

Paris apartments have their own recipe for blocked drains: a mix of how people cook and wash, the city's hard water, and old building stock. The usual causes a plumber finds are:

• Grease and cooking fat. Poured down the kitchen sink, fat looks liquid but cools and hardens in the pipe, catching everything that follows. It's the number-one kitchen blockage.
• Hair and soap. In the bathroom, hair binds with soap scum and shampoo residue into a dense plug that slowly chokes shower and basin drains.
• Limescale from hard water. Paris has notably hard water, and over the years limescale furs up the inside of pipes, narrowing them so they block far more easily.
• Narrow, old waste pipes. Many Parisian buildings still run on tight, ageing waste pipes with sharp bends that were never designed for modern use — they clog more readily than newer pipework.
• Wipes and food scraps. "Flushable" wipes, cotton buds, coffee grounds, rice, pasta and other food that swells in water are frequent offenders, especially in short-let and Airbnb flats with rotating guests.

What the plumber does

A blocked drain isn't cleared by guesswork. The plumber starts with the gentlest method likely to work and steps up only if the blockage needs it, so your pipes aren't damaged in the process:

• Plunger and hand auger. For a single blocked sink or shower, a proper plunger or a hand-fed auger (furet) shifts most soft blockages near the trap quickly.
• Drain rods. For a blockage further down the run, flexible drain rods reach along the pipe to break up and pull out the obstruction.
• High-pressure hydro-jetting. For stubborn grease, limescale and long build-ups, a jet of high-pressure water scours the inside of the pipe clean — the most thorough way to clear a drain (débouchage) without chemicals.
• Drain camera inspection. Where a drain keeps blocking, a camera (caméra d'inspection) is fed into the canalisation to find the exact cause — a collapsed pipe, a bad joint or a hidden root — so the right fix follows.

Once the drain runs freely, the plumber checks it with running water to confirm the blockage is genuinely gone — not just shifted a few centimetres along — and tells you in plain English what caused it and how to keep it clear.

How to prevent blocked drains

Most blockages are avoidable with a few habits. To keep your Paris drains running:

• Never pour fat or oil down the sink. Let it cool and bin it. Wipe greasy pans with kitchen paper before washing up.
• Use a plughole strainer. A cheap sink and shower strainer catches food scraps and hair before they reach the pipe.
• Flush only the obvious. Wipes, cotton buds and sanitary items go in the bin, never down the drain or toilet — even the "flushable" ones.
• Flush drains with hot water. A weekly flush of very hot water, or hot water with a little washing-up liquid, helps shift fresh grease before it sets in hard-water pipes.

What it costs to unblock a drain in Paris

What you pay depends on how bad the blockage is and how it has to be cleared — and we always agree the figure with you before anyone starts. A simple blocked sink or shower cleared with a plunger or auger sits at the lower end; a longer pipe needing rods, hydro-jetting or a camera inspection costs more. As a rough guide, most emergency drain call-outs in Paris fall in the €90–€250 range, with night, weekend and public-holiday visits at the higher end. You get the price before any work begins, and for larger jobs a written quote (devis) — so there are no surprise bills in a language you can't read.
