Yes—some small water leaks can be safely DIY if they’re simple and accessible, but concealed, continuous, or electrically adjacent leaks should be handled by a licensed plumber. Most minor drips come from loose fittings or worn supply hoses that you can tighten or replace after shutting off the water. Larger risks begin when leaks occur in walls or under slabs, where hidden damage and mold can escalate; in our Colorado work, precise, non-invasive detection prevents opening the wrong area and unnecessary demolition. For urgent bursts or active flooding, treat it as an emergency.
- Reasonable DIY: tighten a P-trap nut, replace a faucet washer or supply hose, or reseat a compression fitting.
- Stop and call a pro if you notice a warm floor, a musty odor, a spinning water meter with fixtures off, or the sound of water in walls or under a slab.
- During an active leak: shut off the fixture or main, cut power to wet areas, move electronics, and contain water.
- A pro will perform diagnostic leak detection (pressure testing, acoustic listening, thermal imaging, or tracer gas) to pinpoint the failure and then verify the targeted repair with a pressure test.
If you can’t locate the source quickly, turn off the main water valve and schedule a professional evaluation.
