Leak?Safety first. Isolate water only if safe.
Quick answer
What should you do if a water heater is leaking?
If water is actively escaping, keep clear of hot water and electrical hazards. If it is safe, shut off the cold-water supply to the heater or the home’s main water valve. Do not force a stuck valve, disconnect fittings, or touch wet electrical equipment. If you smell gas, leave immediately and call the gas utility or emergency services from outside.
After immediate safety steps, call to describe the property location and symptoms. We may connect your inquiry with an independent provider if one covers the address; confirm arrival timing, diagnostic fees, credentials, and repair scope directly.

Respond to the leak without making it worse
Water can travel from a fitting or nearby pipe and appear at the base of the tank. Avoid assuming the tank itself has failed until the source is checked.
Isolate only if safe
Use a clearly identified shutoff valve only if you can reach it safely. Do not force corroded controls or dismantle connections.
Describe the symptoms
Note where water first appeared, whether it is continuous, the heater type if known, and what you have safely turned off.
