To fix a leaking home water storage tank, first identify the leak source by inspecting the tank for corrosion, cracks, or loose components. If the tank is metal, check for rust; if plastic, look for punctures. Turn off the water supply, drain the tank, and inspect internally. Repair leaks by replacing damaged sections, tightening bolts, or using epoxy sealants. For severe cracks, consider replacing the tank. Always test the repair by refilling the tank and monitoring pressure. Consult a licensed plumber if the tank is old or complex.

Leak detection and timely repairs are critical to prevent water contamination, structural damage, and mold growth. According to the Environmental Protection Agency (EPA), undetected leaks in water storage tanks can contaminate drinking water, posing health risks. A 2021 study by the American Water Works Association found that 15% of residential water tanks fail due to corrosion, with steel tanks averaging a 10–20 year lifespan and polyethylene tanks lasting 25–30 years. Regular maintenance, including checking valve seals and inspecting tank地基, can reduce failure rates by 70% (Plumbing Foundation, 2020). Delaying repairs can lead to costly property damage, with the Insurance Institute for Property Loss Prevention estimating average repair costs at $5,000 for undetected leaks. Replacing a failing tank typically costs $3,000–$8,000, but proactive fixes save long-term expenses. Data from the National Association of Home Inspectors (NAHI) shows that 30% of home insurance claims involve water damage from faulty tanks, emphasizing the need for prompt action.
