A leaking sink trap can leave a cupboard damp each time you use the sink. This Miami advice article explains what to report to a local plumber and what to avoid while waiting.

Plumber fitting a sink drain trap

Spot a leaking sink trap

The trap is the curved drain pipe below a sink. Water may collect at a joint or drip onto the cupboard base. Stop using the sink if it is leaking and keep the area clear.

Note whether water appears while the tap runs or only after the sink drains. Also report a slow drain, loose connection or recent work under the sink. Do not tighten unfamiliar fittings at random; this can damage parts.

Arrange the right repair

Ask a local plumber to check the trap, seals and nearby connections. The visible drip may not be the only fault. Explain whether the cupboard is wet and whether water has reached the floor.

Before work starts, ask which parts the repair needs and how you will agree on the cost. Keep photos of the area if you can take them safely.

Dry the area around a leaking sink trap

Once the plumber fixes the leak, ask whether the cupboard base or nearby floor needs further drying. Keep an eye on the area during normal use and report any new moisture.

Our plumbing leak information covers other signs to watch for. Have a plumber check a leaking sink trap before repeated leaks damage nearby materials.

For general flood precautions, read the Government of Canada flood safety guide.
