Several plumbing services meet beneath a kitchen sink, so a wet cupboard does not always mean the tap is at fault. The waste fittings, supply hoses and appliance connections each need consideration.

Tracing the source beneath the sink
The plumber checks the affected connection and the conditions under which the leak appears. A slow sink may need drainage work rather than new fittings. When planning a fixture or appliance change, cupboard space, pipe positions and access help establish what alterations are practical.
Where this service can help
- Kitchen sink and mixer repairs
- Leaks in accessible under-sink plumbing
- Water and waste connection assessment for appliances
Confirming the scope
Explain whether you need an isolated fault investigated or several fixtures checked during the same visit. Agreeing that scope first helps distinguish the immediate repair from optional maintenance or additional testing.
Planning fixture changes
Sink depth, waste position and mixer access can affect replacement work. Share the new fixture specifications before surrounding finishes are completed so any necessary plumbing changes can be considered in the right order.
Keeping inspection and repair separate
An investigation may identify more than one practical option. Ask which findings support the proposed repair, whether additional testing would change that decision and what is included in the quoted scope.
Information to have ready
Clear the sink cupboard where practical and note whether the leak follows washing up or appliance use. Share specifications for any new sink, mixer or appliance before connection work is planned.
