Preventing plumbing leaks begins with occasional visual checks around sinks, toilets, exposed pipes, water heaters and appliance connections. Look for corrosion, mineral buildup, dampness, loose connections and stains. Replace worn hoses or fixtures when appropriate, and avoid forcing handles or fittings. Learn where the main water shutoff is located so you can respond if a pipe fails. During renovations, use suitable materials and qualified installation. Insulation may help protect vulnerable pipes in cold conditions, depending on the building and climate. If you see a persistent leak or unexplained moisture, arrange an assessment rather than simply covering the area.
