Water Leaking Under a Sink?

Water under a kitchen sink or bathroom basin can come from the tap, waste pipe, trap, supply pipe or appliance connection. The most useful first details are where the water appears, whether it happens when the tap runs, and whether the cabinet is wet.

Short answer

If water is leaking under a sink, first describe where the water appears, whether it happens when the tap runs, and whether the cabinet is wet. A safe wider photo can help explain the issue.

What to check first

๐Ÿ“ฆCheck the cabinet

Say whether the inside of the cupboard or vanity unit is wet, damp, dripping or holding standing water.

๐ŸšฐRun the tap briefly only if safe

If water appears only when the tap runs, mention that. Do not keep running water if the leak is spreading.

๐ŸงผLook near the waste pipe

Water near the trap or waste pipe is different from water around the tap base or supply pipes.

๐Ÿ’งWatch the leak speed

Mention whether it is a slow drip, steady leak, running water or water spreading into the cabinet.

Do not guess the leak source

Water under a sink can be misleading. A wet cabinet floor does not automatically mean one specific pipe is leaking. Water can travel from the tap base, waste pipe, supply pipe or appliance connection before collecting at the bottom of the cupboard.

A better first message says what is visible: where the water appears, when it appears, how fast it leaks and whether the sink is draining normally.

Water near electrics needs caution.

If water is near sockets, appliances, extension leads or electrical items, keep away from the risk area and include that detail clearly.

Common under-sink leak locations

These are useful ways to describe the leak without trying to diagnose it.

๐Ÿ”งTap base

Water around the base of the tap may appear when the tap is used. Say if the top of the sink is wet too.

๐Ÿช Waste pipe or trap

Water near the sink waste or trap can appear when the sink drains.

๐ŸšฟSupply pipe

A leak from pipework feeding the tap may drip even when the sink is not being used.

๐Ÿฝ๏ธAppliance connection

In kitchens, dishwashers or washing machines can share pipework under the sink.

What to include in your WhatsApp message

Example message

Example

Hi, Iโ€™m in Bilston. There is water under the kitchen sink inside the cupboard. It seems to appear when the tap is running. The sink drains normally and there is a dishwasher pipe nearby.

When it may be urgent

If the leak is steady, water is spreading, the cabinet is full of water, or water is near electrics or appliances, describe it as urgent. If it is a slow drip and contained, still explain clearly when it happens and where the water appears.
