Why Is Water Draining Slowly? Causes & Fixes (Luxembourg)

Slow Drain — The Early Warning Sign

Water draining slower than usual is the #1 early warning of a blocked drain. Fix it now for €150, or pay €1,500 when it floods.

Why It Happens

Bathroom drains — hair, soap scum, toothpaste, and skin cells build up on pipe walls.

Kitchen drains — grease, food particles, coffee grounds, and rice are the worst offenders.

All drains in Luxembourg — hard water leaves limestone deposits that narrow pipes over years.

What Doesn't Work

• Boiling water alone — only clears very fresh, light blockages
• Supermarket drain chemicals — damage pipe seals, hurt the environment, and rarely fix the root cause
• Repeated plunging — pushes the blockage deeper, makes it harder to remove

What Actually Works

1. Mechanical removal — drain snake (furet) for hair clogs near the surface
2. High-pressure jetting — scours grease and limestone off pipe walls
3. CCTV inspection — finds the real cause (tree root? collapsed pipe? wipe ball?)

When to Call a Pro

• Multiple drains slow at once → main line issue
• Gurgling or bad smell → venting/sewer problem
• DIY isn't working after 1 attempt
• Toilet rising when you run the sink

Cost in Luxembourg

• Single drain clearing: €100–€220
• High-pressure jetting: €200–€450
• CCTV inspection + jetting: €250–€500
