Why does it only leak when the sink drains?
That often points towards waste pipework or seals rather than a pressurised water supply.

Water leaking under the sink: what should you do?
Leaks can come from supplies, wastes, taps, seals or appliances. The first priority is limiting damage safely and identifying whether the leak is continuous or only occurs during use.
What to do next
A sensible first check
✓ Move stored items away from the leak
✓ If safe and appropriate, isolate the affected water supply
✓ Dry the area and observe when water reappears
✓ Avoid using electrical appliances in wet areas
When should you act?
Continuous leakage, water near electrics or damage spreading into floors or units needs prompt attention.
This page is general guidance, not a diagnosis. If the issue involves immediate danger, active water near electrics, fire, gas, structural instability, unsafe working at height or another urgent safety risk, use an appropriately qualified professional or emergency service rather than relying on online advice.

Common questions
Can I use tape as a temporary repair?
Improvised repairs may not be reliable; controlling the water and arranging a proper repair is safer.
