A leaking water heater is never something to ignore. Even a small drip can turn into water damage if the source is not found quickly. Some water heater leaks are simple repairs, while others mean the tank is failing and needs to be replaced.
Check the Water Connections
Hot and cold water connections at the top of the heater can loosen, corrode, or wear out. If water is dripping from a pipe connection, fitting, or supply line, a plumber may be able to repair or replace the affected part.
Drain Valve Leaks
The drain valve near the bottom of a tank water heater is used during maintenance and flushing. If it is not fully closed or has worn out, it can drip. In some cases, the valve can be tightened or replaced.
Temperature and Pressure Relief Valve
The temperature and pressure relief valve is an important safety component. If it is leaking, the valve may be faulty, the pressure may be too high, or the water heater may be overheating. This should be checked by a professional.
Leaks From the Tank Itself
If water is coming from the tank body or pooling underneath with no clear valve or pipe source, the tank may be corroded internally. A leaking tank usually cannot be repaired safely and typically requires replacement.
Why Fast Action Matters
Water heater leaks can damage floors, walls, cabinets, baseboards, and nearby belongings. Moisture can also lead to mold concerns if it sits too long. Shutting off the water supply and calling a plumber quickly can limit damage.
What You Should Do First
If safe, turn off the water supply to the heater. For gas units, turn the gas control to the proper off or vacation setting if needed. For electric units, shut off power at the breaker before touching wet areas. Then call a plumbing professional.
