A leaking water heater can have several causes. Identifying the source is the first step toward choosing the right solution.Loose Connections
Cold water inlet and hot water outlet pipes may loosen over time because of vibration and normal expansion. Tightening fittings or replacing worn connectors often resolves minor leaks.Faulty Temperature and Pressure Relief Valve
The T&P relief valve is a critical safety component. If it leaks, excessive pressure inside the tank or a failing valve may be responsible. This issue should never be ignored.Drain Valve Problems
Sediment buildup or an aging drain valve can allow water to seep from the bottom of the tank. In some cases, replacing the valve is enough to stop the leak.Tank Corrosion
Older storage water heaters naturally develop rust after years of use. Once the internal tank corrodes, replacement is usually the safest and most cost-effective option.Signs Your Water Heater Needs Immediate Attention
Not every leak begins with a puddle. Watch for these warning signs:- Water collecting around the base
- Rust-colored water from faucets
- Inconsistent hot water
- Strange popping or rumbling sounds
- Visible corrosion
- Higher monthly water bills
- Damp flooring near the unit

Step 2: Shut Off the Water Supply
Locate the cold-water shutoff valve above the heater and close it to stop additional water from entering the tank.Step 3: Inspect the Leak
