• water drains slower than usual,
• gurgling sounds in the sink, shower or toilet,
• unpleasant odors coming from the drains,
• water level rises before going down again.

These signs show that a blockage is already forming. Acting early can often prevent a full emergency.

Good practice (hot water + dish soap):

1. Pour a generous amount of dish soap into the sink.
2. Heat a large quantity of hot water (not boiling).
3. Fill the sink completely.
4. Release the water all at once to create strong pressure in the pipe.

The force of the water, combined with the lubricating effect of the soap, often helps loosen grease before it hardens. When applied early, this method can save you money.

Why you should not wait:
Most kitchen blockages are caused by grease and food waste. Over time, this mixture cools down, hardens and makes unblocking much more difficult, even with professional tools.

Before the plumber arrives:
Empty the cabinet under the sink to allow direct access to the siphon and pipes.

• Use a standard plunger with slow and steady movements.
• Make sure there is enough water in the toilet bowl.
• Avoid flushing repeatedly.

Common mistake to avoid:
If a toilet deodorizer block is present, using a plunger may push the block deeper into the pipe, making the blockage harder to reach.

Chemical drain cleaners are often counterproductive:

• they mix with solid grease and create a hard mass,
• they can further clog the pipe,
• the intervention becomes longer and more expensive.

Additional risk: on stainless steel sinks, these products can cause persistent black stains.
