Why Is Your Water Heater Leaking?
A leaking water heater can have several causes. Identifying where the water is coming from is the first step toward an effective repair.Loose Plumbing Connections
The cold-water inlet and hot-water outlet connections may loosen over time because of vibration and normal wear. Tightening or replacing fittings often solves the problem when caught early.Pressure Relief Valve Problems
The temperature and pressure relief valve is a critical safety component. If it begins dripping regularly, it may indicate excessive pressure inside the tank or a faulty valve that requires replacement.Drain Valve Leaks
The drain valve near the bottom of the tank can wear out or fail to close completely after maintenance. In many cases, replacing the valve eliminates the leak without replacing the entire unit.Tank Corrosion
Older water heaters may develop internal rust that eventually creates cracks in the tank. Once the tank itself is leaking, replacement is usually the most practical solution.Signs You Should Never Ignore
Not every water heater failure begins with water pooling around the tank. Watch for these early warning signs:- Standing water around the base
- Rust-colored water from faucets
- Unusual popping or rumbling sounds
- Inconsistent hot water supply
- Increased utility bills
- Moisture on nearby walls or flooring
- Corrosion around fittings and valves
