Homes with natural gas have a main shut-off valve typically called the “street-side valve.” It is located just before the gas meter and looks like a rectangular nub. For single-family houses, the gas meter is typically located outside of the house on the side or in the back. They are usually only located indoors in businesses or multi-family residences.

Do you see a flying saucer-shaped mechanism on the copper pipes? This is called the “regulator,” and the main shut-off valve is probably located right above it.

You can differentiate gas pipes from water pipes by noting that iron pipes transporting gas are often black, while water pipes can be gray galvanized steel.

Another main gas shut-off valve is the “house-side valve.” This valve is typically a ball valve and might be located where the gas pipe first enters the house. Even if it’s located further down the line, it will always be located before the first appliance that connects to the gas line.

Series LFMMV Thermostatic Mixing Valves maintain and limit mixed hot water to a desired, selectable temperature. The LFMMV series can be set to any temperature between 80 deg F and 120 deg F with flow rates as low as 0.5 gpm and as high as 12 gpm (refer to capacity chart on back). This mixing valve series is listed under ASSE 1017 for valves used in hot water source applications, ASSE 1069 for single-pipe, tempered water applications and ASSE 1070 for valves used in individual or multiple fixture applications and also listed IAPMO cUPC. The LFMMVs feature Lead Free* construction to comply with Lead Free* installation requirements. The LFMMV-M1 uses a double throttling design to control both the hot and cold water supply to the mixed outlet. The superior flow characteristics of this valve provide accurate temperature control (+/-3 deg F) with low pressure drop across the rated flow range. As an added feature, the LFMMV-M1 series incorporates integral inlet filter washers and check valves in both the hot and cold water inlets to protect against cross flow. The LFMMV-M1 is available with either union thread (-UT), union solder (-US), CPVC (-CPVC ) Quick-Connect (-QC) or PEX (-PEX) end connectors. Maximum Pressure: 150psi (10.55 bar).

You’ll sense a theme going forward— when valve levers are parallel to the gas pipe, that means the pipe is open and gas is flowing through. To turn off the gas supply, turn the lever perpendicularly. On the copper pipes of a high-pressure gas system, the levers are smaller than others you might see.

And when an issue arises or you want to perform work on an appliance, you don’t want to be scrambling trying to track down your gas shut-off valve. So that’s why we’re here to help!

These valves allow you to stop the flow of gas to the following appliances without shutting off the gas for the entire home:

When the rectangular nub is turned a quarter turn to be perpendicular to the incoming gas line, that’s how you know it’s closed. This valve must be opened and closed with a wrench. Gas companies prefer professional plumbing contractors to handle the opening and closing of the main street-side shut-off valve.

For homes with propane or liquefied petroleum gas, the main shut-off valve is located on the tank itself. Additionally, there’s a main shut-off valve located before the first appliance connection.

If your gas valve was manufactured before 1980, it could contain a lubricant that was meant to help operate the valve more smoothly. However, this lubricant can harden over time making it difficult to turn. You can use pliers to free up the stuck handle and apply a gentle flow of heat with a hairdryer to loosen the valve.

If your home has a high-pressure gas system, your indoor main shut-off valve is likely located near your water heater or furnace in the utility room.

Now, let’s move on from main gas shut-off valves to individual valves. Every gas-reliant appliance in your home should have an individual shut-off valve that is in the same room as the appliance. Typically, the individual shut-off valve is no further than 6 feet away from the appliance.

Gas valves vary greatly in shape and location depending on your location, local codes, and the age of your home. But, depending on the type of valve you have, you can usually find it in these five common places.

We’d wager that the average homeowner doesn’t sit around and think about the type of gas line they have and where to find the gas shut-off valve in their home. In a properly functioning home, you can usually let your gas shut-off valve stay out of sight and out of mind until you need to address an issue.

You don’t usually need professional help to turn off a house-side ball valve. There will likely be a lever connected to the valve. If the lever is parallel with the pipe, that means the pipe is open. To close it, turn the lever 90 degrees so that it forms a right angle to the pipe.
