Slow leaks are dangerous because they are quiet, familiar, and easy to postpone. A major burst pipe gets attention. A tiny drip under a sink gets ignored while it damages cabinet bottoms, stains drywall, softens subflooring, and supports mold growth or pest activity. That is why I teach homeowners to stop waiting for dramatic plumbing failures and start looking for subtle evidence.
Here is a practical routine. Open the cabinet doors under sinks. Look at the trap, supply valves, shutoffs, and drain connections. Check around toilets, dishwashers, refrigerators with ice makers, and washing machine connections. Use your nose and your hands. Musty odors, water spots, swelling particleboard, rust on supply lines, mineral deposits, and dampness on a paper towel are all useful clues. In kitchens and baths, also pay attention to gaps around pipe penetrations and signs that water is escaping where it should not.
EPA WaterSense says homeowners should monitor faucets for leaks by listening for drips and looking under sinks for leaks at pipe connections, puddling, or other water spots. Oregon State Extension also advises inspecting bathrooms and kitchens for leaks and gaps around pipes. That is straightforward and smart.
