A leaking water heater can quickly become an expensive problem, especially for a first-time homeowner suddenly trying to figure out whether to shut off the water, the gas, or both.
One Reddit post captured that all-too-familiar moment of panic — and the practical advice that followed.
Here's what to know
The homeowner said in a Reddit post that they had already stopped the leak by shutting off the unit's water supply, but they were still unsure whether to turn off the gas too. "Hello! First time homeowner and not sure what I should be doing," they wrote.
Most of the advice focused on preventing the heater from continuing to fire. Commenters pointed the poster to the unit's own gas control, with one saying, "Just turn the gas valve/thermostat on water heater to off."
Another added, "You can also turn the thermostat control all the way down to off for the water heater."
If a replacement is necessary, homeowners can see energy bill savings by upgrading to a heat pump water heater.
More background
Water heaters are often tucked away and largely ignored until something goes wrong, and the shutoff points are not always easy to identify.
The poster also mentioned that the suspected valve was difficult to move, and that an inspector's tag appeared to indicate the gas should be shut off as well.

Because the valve appeared to be older, commenters said it might be stiff enough to need a wrench. At the same time, another person suggested not forcing an upstream valve if there was no smell of gas and professional help was already on the way. Switching the heater's own control to "off" was described as the simpler way to stop it from firing without risking aging gas hardware.
What can be done?
As one commenter put it, "You just don't want the burner running if the water is draining from the tank."
