A slow drip under the sink can feel like a weekend project. Sometimes it is. But small leaks can also be the visible edge of a bigger problem inside a wall, floor or ceiling. Knowing which signs need prompt attention can save you from water damage and mold.
Key takeaways
- Know where your main water shut-off valve is before you need it.
- Stains, bulges and musty smells often mean hidden water.
- Rising water bills with no change in use can signal a leak.
Call a plumber promptly if you notice
- Water stains or bubbling paint on ceilings or walls.
- Warped or soft flooring near bathrooms, kitchens or laundry areas.
- A musty smell that does not go away.
- The sound of running water when everything is turned off.
- A water heater leaking from the tank itself.
- Low water pressure throughout the house.
What to do first
- Turn off the fixture’s shut-off valve or the main water supply.
- If water is near outlets or appliances, turn off power to that area if it is safe to do so.
- Move belongings away from the wet area and start drying.
- Take photos for your records and for insurance if needed.
Questions to ask the plumber
- What caused the leak, and is it likely to happen elsewhere?
- Is the repair a patch or a permanent fix?
- Will walls or floors need to be opened, and who repairs them?
- Is the price fixed, or based on time and materials?
A quick leak check you can do
Turn off every faucet and water-using appliance, then note your water meter reading. Wait an hour without using any water and check again. If the reading has changed, water is going somewhere it should not.
FAQ
Is a dripping faucet urgent?
