Is water heater on a gas line?

[Kaushik R.]

The water heater is turned off (no light on the dial - used to be green) and there's no hot water in the unit. Circuit breakers are fine. Is it because the gas connection was turned off and this heater needs gas to operate? Thank you.

Yes, that yellow flex line is the gas supply to the heater. You need to restart the gas and then light the pilot light on the heater. Usually there is a dial that has a 'pilot' spot on it and then you push the ignitor until the burner lights.
