Gas has a distinctive odor and most times you can locate the source of the leak by following this odor. If you smell gas you should temporarily turn off the power to the home until you can locate the source this will reduce the risk of the gas being ignited.

Some places to check for a gas leak would be your gas stove, see if the pilot light has gone out if that is not the case check to make sure all the burners and the oven are turned to the off position. Next check your gas water heater to make sure the lines have not come loose. If you find a loose connection and feel comfortable enough to fix it yourself follow these instructions:

You will need some leak detector, place this on the threaded connections and wait and see if it bubbles up, check all connections to ensure you found all the leaks.

Once you have located the all the leaks, turn off the gas before fixing.

After the gas has been shut off, you can repair most of these leaks by tightening the connections with a pipe wrench.

If you feel you have the leaks taken care of turn the gas back on and test again to see if there are anymore leaks.

Some other things to keep in mind when dealing with a gas leak is that the gas fumes will hover close to the ground not at the ceiling, so make sure you are opening doors and windows to ventilate and never strike a match or create any sort of spark until the fumes have completely dissipated.
