The gas heater pilot light has been out for a couple of days, and I believe there is a safety mechanism that detects this, and shuts off the gas. Now, when I move the slider to the pilot light position and press the valve button, I don't hear any gas coming out. Is there anything I need to do to
You may not be able to hear the gas for the pilot light, it doesn't take much. Get a long match or lighter that can reach the pilot light and try to ignite it while holding down the valve button. That button overrides the thermocouple that will automatically shutoff the gas when it cools down. You need to hold the button long enough to heat the thermocouple back up while the flame is burning (30-60 seconds is usually good). Once the flame stays lit without holding the button, you can close the water heater back up and adjust the tank thermostat back to your normal temperature.
