What to do when you find a plumbing leak

The best first response to a plumbing leak is to limit ongoing water exposure without creating a new safety risk. What you do next depends on the location of the leak, the amount of water, and whether electrical equipment or ceilings are involved.

Put safety first

Avoid standing water near electrical outlets, appliances, or panels. If water is actively spreading and it is safe to do so, use the nearest fixture shutoff or the home’s main water shutoff. Do not force a valve that will not move or enter an unsafe area to reach it.

Document the conditions

Take photos or video of the visible source, affected surfaces, and any items that may be damaged. Note when you first noticed the issue and whether the leak appears continuous or tied to using a specific fixture. These details can help a plumber identify the next checks and may be useful for an insurance conversation.

Reduce secondary damage

Move belongings away from water where it is safe, and remove standing water from accessible hard surfaces. For a substantial leak, a saturated ceiling, or water that may be contaminated, seek prompt professional guidance on both the plumbing source and drying needs.

Prepare for an assessment

Share the location, photos, water-shutoff status, recent plumbing work, and any changes in water pressure or drainage. Ask what the assessment includes and whether the proposed repair addresses only the visible leak or a related underlying condition.
