Water leaking under a sink
If water is actively escaping, turn off the fixture shutoff valve if you can safely reach it. A plumber can discuss the supply, trap, drain or connection; soaked cabinetry may also call for water damage assessment.
Leaking pipe, slow drain, no hot water, or an unexplained high water bill? Start with the symptom, understand the right plumbing service, and use the plumbing-specific contact line.

Start with what is happening—not a long list of services. The right next step depends on whether water is actively escaping, a fixture is blocked, hot water has stopped, or a hidden leak is suspected.

Unexpected water use, damp flooring, or the sound of running water may warrant hidden or slab leak investigation. Do not assume a slab leak without testing; ask how the line would be located before demolition.
A single sink clog and a multi-fixture backup are different problems. Avoid running more water when drains are backing up; ask about drain clearing, camera inspection and whether the main sewer line may be involved.
Record whether the issue affects one fixture or the whole house, and whether the unit is tank or tankless. Do not open electrical panels or gas controls; discuss safe water heater diagnostics.
| Situation | What to look for | Service to discuss |
|---|---|---|
| Fixture or supply leak | Water appears around a faucet, toilet, sink or visible pipe | Plumbing leak repair |
| Hidden or slab leak | Unexplained water loss, damp floors or suspected concealed line | Leak detection |
| Drain or sewer blockage | Slow drains, gurgling, sewage or multiple backups | Drain and sewer service |
| Property materials already wet | Damaged cabinets, flooring, drywall or lingering moisture | Water damage restoration alongside plumbing |

Three useful things to check before discussing a visit.
If water is escaping continuously or spreading, shutting off the affected supply can limit damage. If you cannot identify the correct valve, seek professional guidance.
Multiple affected fixtures can point to a shared drain or sewer-line problem rather than an isolated sink clog.
Yes. Even a small continuous leak wastes water over time and may signal a component that needs repair.
