Start with the source
What a leak from this area may mean
If water is actively escaping, treat it as urgent. Keep people away from the water and any electrical equipment, do not open the heater, and call for qualified assistance. If you smell gas or a carbon-monoxide alarm sounds, leave the property and contact emergency services from a safe location.
For broader guidance, see our water heater leak repair information for Union, NJ or call to explain what you are seeing. The provider can confirm whether it handles the specific system and issue.

Possible causes
What may be behind the leak
More than one component can create similar symptoms. An A. O. Smith technical bulletin lists condensation, drain-valve leakage, T&P relief-valve leakage, inlet/outlet piping, gas-valve threaded connections on gas models, electric-element gaskets on electric models, and tank leaks among potential causes of a puddle or water in a drain pan. The correct cause depends on the actual heater and installation.

Possible leak sources
Use the visible clues to describe the issue, not to attempt your own repair. The provider can inspect the equipment and trace the moisture.
For a tank confirmed to be leaking through its shell, manufacturer guidance indicates the tank should be replaced. Other leak sources may have different repair options.
Professional diagnosis
What an independent plumbing provider may check
- Keep children, pets, and other occupants away from the appliance and standing water.
- Do not touch electrical equipment or controls in a wet area.
- Do not cap a relief valve, remove covers, or drain a hot or pressurized tank.
- Explain the amount and location of water, whether it is still flowing, and whether there is a gas odor or CO alarm.

Safety first
What to do while arranging help
Heater Shield does not promise 24/7 or same-day attendance. Calls are forwarded to an independent local provider, who must confirm availability and the appropriate response. If there is a gas odor, leave and call 911 or the gas utility from a safe location. If a carbon-monoxide alarm sounds, move outside to fresh air, call emergency services, and do not re-enter until responders permit it.
For a suspected carbon-monoxide event, the U.S. Consumer Product Safety Commission says to move outside to fresh air, call emergency services, and not re-enter until responders permit it.
