Dripping tap: how to repair it

In short: A dripping tap usually has a worn seal or cartridge. This can be repaired yourself in a few steps and saves water.

In more detail: One drop per second can waste several thousand litres of water per year.

In detail

• Turn off the water: Close the angle valve under the basin; open the tap until no water comes out.
• Protect the drain: Insert the plug or place a cloth in it so nothing falls in.
• Dismantle the tap: Pry off the cap, loosen the screw, pull off the handle.
• Single-lever mixer: Remove the cartridge and buy the same model.
• Two-handle tap: Unscrew the top part, change the sealing ring or washer.
• Limescale: Remove with vinegar or citric acid.
• Reassembly: Fit parts in reverse order, turn the water on slowly.
• Help: For damaged pipes or a rented flat inform the landlord or plumber (werkzeug-grundausstattung-fuer-zuhause).
