As a homeowner, you need to be aware of the potential for problems that can occur and what needs to be done in order to head off those problems, when they do occur. The classic example of this is if you detect a gas leak or if there are any problems which would require you to shut off the gas to the home quickly. Although this is something that can be done easily, most people are not even aware of how to shut off the gas or even the location of the gas shut off valve. Here is how to find it easily so that it will not be an issue for you in the future.
The first thing that you should understand is that there is more than one type of gas shut off valve. The main valve is the one that you would be interested in if you are trying to shut off the flow of gas throughout the entire house. There may also be shut off valves that are specific to appliances or various fixtures within the home. It’s a good idea for you to identify those individual supply shutoff valves so that you can turn them off quickly, if you have a problem with one of those appliances.
If you’re looking for the main shutoff valve, it is typically located near the gas meter. This type of valve is sometimes referred to as a street-side valve and it will usually look as if it is a square nub with a handle on it. Make sure that you locate this valve today so that you can use it if necessary in the future (Source: MB Services Excess Flow Valves).
