To fix a leaking basement drain pipe, first turn off the water supply and wear protective gear. Remove the drain cover to access the pipe, inspect for cracks or corrosion, and tighten loose joints with a pipe wrench. Apply waterproof sealant around the pipe and replace damaged sections if necessary. Reassemble the drain and test for leaks.

Leakage in basement drain pipes often stems from corrosion, cracks, or loose connections, which can lead to mold growth and structural damage. According to the Environmental Protection Agency (EPA), mold can develop within 24–48 hours of water exposure, increasing health risks and property repair costs. A 2021 study by the American Society of Civil Engineers found that 20% of homeowners in the U.S. experience annual basement leaks, with pipe failures accounting for 35% of cases. Prompt repair prevents water seepage, which can degrade floors, walls, and foundations. Waterproof sealants and epoxy resins, as recommended by the DIY Network, extend pipe lifespan by 10–15 years. Replacing corroded pipes entirely, rather than patching, reduces recurrence by 70%, per a 2020 report by HomeAdvisor. Proactive maintenance aligns with industry standards, such as those outlined by the International Association of Plumbers and Pipefitters, which emphasize regular inspections and corrosion-resistant materials like PVC or CPVC. Addressing leaks swiftly saves an average of $2,500 in repair costs, as cited by .
