Plumbing repair guide

Tap dripping after it is turned off?

A drip from the spout, a leak around the handle, and water beneath the sink point to different places. Note whether the tap is hot or cold and whether the drip changes when the handle moves. Do not force a stiff handle.

What may be happening

Common clues

  • Worn washer or cartridge

    A steady drip from the spout can come from a worn internal seal or cartridge. Tap designs vary, so a part that fits one model may not fit another.

  • Loose or damaged connection

    Water around the base or beneath the sink can come from a supply connection or body seal rather than the spout.

  • Scale or handle wear

    Mineral deposits or worn controls may stop a tap closing fully. Forcing the handle can damage the valve and increase the leak.

Start safely

Useful checks before calling

  1. 1
    Identify the drip location

    Dry the outside of the tap and observe whether water returns at the spout, handle, base, or under the sink.

  2. 2
    Use the handle gently

    Turn the tap off normally without overtightening. A handle that feels stiff, loose, or gritty should not be forced.

  3. 3
    Check the cupboard safely

    Look for dampness under the sink without touching electrical equipment or moving heavy stored items. Place a container under a small drip if safe.

  4. 4
    Find the isolation valve only if needed

    If a leak is worsening and the valve is clearly accessible, close it gently. Do not force a seized valve or disconnect any pipe.

Safety comes first

Keep water away from electrical appliances and sockets. If a pipe is spraying or water is reaching electrics, keep clear and get urgent help.

Know when to hand it over

When to contact a repairer

A plumber can identify the correct cartridge or seal and check for a supply leak. Arrange help if the drip persists, the handle is damaged, or water appears under the sink.

Useful details to have ready

  • Whether the leak is at the spout, handle, base, or pipe
  • Tap make or model if visible
  • Whether the leak changes when hot or cold water is used
More about this fault

Common questions

Can I tighten the tap handle to stop the drip?

Do not overtighten it. A drip often comes from an internal seal or cartridge, and extra force can damage the handle or valve.

Does every dripping tap need a new tap?

Not necessarily. Some taps need a replaceable seal or cartridge, while others have different faults. A plumber can identify the correct part for the model.
