Quick answer
Turn off the cold-water supply valve at the top of the heater, then switch off the breaker (electric) or set the gas control to Off (gas). Next, find where the water is coming from: a leak from a fitting or valve is often repairable, but a leak from the tank body means the heater needs replacement.
Step by step
- Shut the cold-water inlet valve
- Turn off power or gas
- Keep clear of the relief valve outlet — water may be scalding
- Look for the source: top connections, relief valve, drain valve, or the bottom of the tank
- Call 813-600-3797 with what you found
Where it's leaking tells you a lot
- Top fittings: loose or corroded connections — usually repairable
- Relief valve: possible excess pressure or temperature, or a worn valve — needs checking
- Drain valve: often a worn valve — repairable
- Tank bottom or body: internal corrosion — replacement needed

Common questions
Can I still use hot water with a small leak?
It's not recommended. Small tank leaks tend to grow, and a failing tank can release a lot of water.
