What Is a Seismic Gas Shutoff Valve?

Let’s get to know what a seismic gas shutoff valve is before discussing all the expenses related to it. First off, you should know that this item is also sometimes known as an earthquake gas shutoff valve. Those names should already clue you into the importance of this particular item.

The job of the seismic gas shutoff valve is to prevent the effects of a disaster from getting worse. When an earthquake strikes, various items inside your home may fall over, crack open, or shatter. Important connections such as electrical wires and gas lines may also be damaged by the impact of an earthquake.

A busted gas line becomes especially dangerous in that scenario. The continuous flow of gas into your home can easily lead to a fire. Of course, it can also get significantly worse than that. There’s also a chance that the accumulation of gas inside your home can trigger an explosion. You can imagine just how disastrous such an occurrence could be.

The seismic gas shutoff valve’s job is simple. In the event of an earthquake, it will automatically stop the flow of natural gas into your home. The earthquake may still devastate your home, but at least you’ll stop from it catching on fire due to the gas. The damage will not be as bad as it could have possibly been.

Earthquake gas shutoff valves are incredibly valuable because of how helpful they are during an emergency. You may not always have the presence of mind to shut off the gas in the middle of an earthquake. With the valve installed, that’s one fewer thing you’ll have to worry about.

Is Installing a Seismic Gas Shutoff Valve Required?

Whether or not you’ll be required to install an earthquake gas shutoff valve will depend on where you live. Places where earthquakes are relatively common often require residents to install seismic gas shutoff valves.

Many municipalities throughout the state of California have those laws. You can understand why given the state’s history when it comes to earthquakes.  It’s best to check with your local government and ask about the requirements pertaining to shutoff valves.

Should you skip out on installing a seismic gas shutoff valve if it’s not required in your area? That’s for you to decide. It’s difficult to deny the value of that valve if you live in an earthquake-prone area though.

Cost of Seismic Gas Shutoff Valve

Gas Line Diameter Valve Price
3/4 of an Inch $100
1 Inch $200 to $300

The main factor that will affect the price of your seismic gas shutoff valve is the size of your gas line. We’re not talking about the length of the gas line here. The diameter of the gas line is what you need to know if you’re buying an earthquake gas shutoff valve.

Numerous homes throughout the country use gas lines that are about 3/4 of an inch thick in terms of diameter. The appropriate valve for pipes of that size will cost about $100.

Your gas line may be slightly thicker, measuring at a full inch in terms of diameter. In that case, the valve you’ll need may cost $200. A more expensive valve – one priced at close to $300 – may be required depending on the pressure in your gas line.

It’s worth noting here that there are thicker gas lines and valves that correspond to them on the market. Some gas lines will measure up to four inches in diameter and some are even double that in terms of thickness.

Those gas lines are usually reserved for commercial establishments. They are not really needed for residential settings. You don’t have to worry about paying for the valves that can fit those larger gas lines.

Should You Use Appliance or Main Shutoff Valves?

The shutoff valves we’re talking about in this article are the ones that will control the main source of natural gas. That’s part of the reason why they are so expensive.

Notably, though, you can also find gas shutoff valves for individual appliances. Those valves are way more affordable. Even the most expensive appliance valves cost around $40 tops. You can find some appliance valves that are sold for $15.

Given the potential savings, should you consider using an appliance shutoff valve in place of a seismic gas shutoff valve? Wanting to save money is understandable, but this is not the area where you should try to do that.

Going with individual appliance valves is risky. One of them can malfunction and still cause an explosion inside your home. It’s better to go to the source of the gas and cut off the supply right there.

Also, you may not be able to save that much money even if you opt for the individual valves. Equipping multiple appliances with a shutoff valve can lead to costs piling up in a hurry as well.

How to Find a Seismic Gas Shutoff Valve

You cannot just pick up any seismic gas shutoff valve and expect it to be a good fit for your home. Doing so could lead to you wasting money. Homeowners must first gather some information before making a purchase. Start by getting in touch with the relevant authorities in your area.

Usually, the Department of Building and Safety is the one you must contact if you have questions regarding gas shutoff valves. Reach out to them and ask about their requirements for shutoff valves. They should be able to tell you what size and type of valve you should purchase.

After finding out the specific kind of gas shutoff valve you need, you can start looking for it. Look online or in hardware stores for the gas shutoff valve. If you’re busy, you can also talk to the installer as they may have a valve suitable for your home already. You can just pay them extra for the valve and for the installation.

Labor Cost for Installing a Seismic Gas Shutoff Valve

Professional Service Hired Expected Total
Low-End Option $250
Mid-Range Option $300
High-End Option $400

How much will you have to pay to get a seismic gas shutoff valve installed? That will depend on which service you hire. This is where scouting the service providers in your area will be crucial.

Some installers will take on this job for $250. In exchange for that fee, they will handle the installation from start to finish and also supply certain items. They will also handle the tasks needed prior to installation.

That $250 fee will not include the earthquake gas shutoff valve though. You will have to pay extra if you’re getting that item from them as well. You can also find services that will charge $300 to $400 for the installation. The more experienced installers are the ones who usually charge extra.

Can You Get Discounts on Seismic Gas Shutoff Valve Installations?

Seismic gas shutoff valve installations aren’t especially pricey, but saving money on them whenever possible is still ideal. So, is it possible to get a discounted deal on your installation? That will ultimately depend on which service you’re working with.

Take the time to search for installers who offer package deals. The package deals often entail getting multiple earthquake gas shutoff valves installed at the same time. Package deals are great for apartment residents or for those who live in homes that are clustered together. You can pool money together with your neighbors and secure a pretty good deal.

Discounts for multiple appliance installations are less common. You may have to pay full price for those installations. That’s another reason why going for the seismic gas shutoff valve can turn out to be the better choice.

How Long Will the Seismic Gas Shutoff Valve Installation Take?

Assuming the spot where the valve needs to be installed is accessible and in good condition, the job won’t take long. The installation could be finished in about two to three hours. You’ll be able to use your gas-powered appliances on the same day you get the valve installed.

Remember the estimated completion time for the installation if you’re still looking for a service to hire. Some of the installers in your area may prefer to go by an hourly rate instead of a fixed fee. Note their hourly rate and the expected completion time for the job to figure out if you’re getting a good deal.

How Much Do You Have to Pay for New Gas Lines?

The installers will inspect your gas lines before they proceed with the job. Upon doing so, they may find that your gas lines are in poor condition. They may suggest removing and replacing your gas lines prior to installing the shutoff valve. You’re in for a way larger bill if that’s the case.

Removing the gas lines is going to cost a lot of money. Professionals will typically charge around $6 per linear foot of gas line removed. You could be looking at an expense of $600 once all the damaged gas lines are removed.

Installation is going to be even more expensive. Don’t be surprised if you’re given a bill of close to $2,000 for your new gas lines.

Homeowners are potentially looking at an additional $2,600 being added to their expenses. Keep in mind that the valve installation is still not included in that total. Avoid paying for gas line replacement earlier than expected by properly maintaining them.

Do You Need a Permit before Installing a Seismic Gas Shutoff Valve?

Permit requirements for seismic gas shutoff valve installations are going to vary from one state to the next. It may even vary depending on the municipality you’re in.

Talk to the professionals you hired about the permit requirements in your area. They’ll let you know if securing a permit is necessary or if you can just go ahead with the installation.

Permits for this type of installation are also pretty affordable. They cost around $80 at most.
