When an earthquake hits El Dorado Hills, you won’t be wondering if your gas lines are intact. Your earthquake shut-off valve automatically cuts the gas supply the moment it detects seismic activity measuring 5.4 or higher. No more worrying about gas leaks turning into house fires while you’re stuck in traffic or at work.
The peace of mind is immediate. Your home becomes a safer place for your family, and many insurance companies recognize this with policy discounts. You’ve eliminated one of the biggest fire hazards that follow major earthquakes—broken gas lines that leak dangerous natural gas into your home.
After installation, you’ll have a system that works 24/7 without any input from you. It’s there when you need it most, during those unpredictable moments when the earth moves and everything else feels uncertain.
We’ve been serving El Dorado Hills and surrounding areas for over two decades. We’re the local plumbing company that homeowners call when they need earthquake shut-off valves installed correctly the first time.
Our team understands the seismic realities of living in Northern California. El Dorado Hills sits in an area with moderate seismic activity, and we’ve seen what happens when homes aren’t properly prepared. That’s why we take earthquake valve installation seriously—your family’s safety depends on it.
As a family-owned business, we keep our overhead low and pass those savings on to you. We’re licensed, insured, and have earned our 5-star reputation by showing up on time, doing quality work, and charging fair prices that sometimes come in under our original estimates.
First, we assess your current gas meter setup and determine the right valve size for your home’s gas line. Most residential installations use valves between 3/4″ and 2″, depending on your home’s gas consumption needs.
Next, we temporarily shut off your gas service and install the seismic shut-off valve on your house line—never on the utility company’s equipment. The valve contains a motion-sensitive mechanism with a steel ball that rests on a tapered support. When horizontal earthquake motion occurs, the ball shifts and triggers the valve to close automatically.
After installation, we test the system and restore your gas service. The entire process typically takes a few hours, and you’ll have a safety device that requires no maintenance or monitoring. If the valve ever activates during an earthquake, we can help you reset it after a proper safety inspection confirms no gas leaks exist.

Your earthquake valve installation includes the UL-certified valve itself, all necessary fittings and stabilizer brackets, and professional installation that meets California state requirements. We use only valves approved by the State of California and manufactured to ASCE 25-06 standards.
El Dorado Hills homeowners need to understand the local seismic landscape. Our area experiences an average of 68 earthquakes per year, with larger magnitude 5+ earthquakes occurring approximately every 10 to 15 years. The USGS shows a 60.94% chance of a major earthquake within 50km of El Dorado County in the next 50 years.
We handle all the technical details, from selecting the right valve orientation (horizontal, vertical up, or vertical down) to ensuring proper installation on your house line rather than utility company facilities. Our installation comes with a warranty and the confidence that comes from working with licensed professionals who’ve been installing these safety devices throughout Northern California for over 24 years.
Installation costs typically range from $600 to $1,200, depending on your specific setup and valve requirements. This includes the valve itself (usually $150-$500), professional labor, any needed permits, and all fittings and brackets.
The price varies based on factors like your gas line size, accessibility of your meter, and whether additional piping work is needed. We provide free estimates so you know exactly what to expect before we start work. Many homeowners find that insurance discounts help offset the installation cost over time.
While not currently mandated by El Dorado Hills specifically, many California cities require earthquake shut-off valves, especially for home sales. Some insurance companies also require them for coverage in seismic zones.
Even without a local requirement, installing an earthquake valve is one of the smartest safety investments you can make. Given that El Dorado Hills has moderate seismic activity with a 60.94% chance of a major earthquake in the next 50 years, the protection these valves provide far outweighs the installation cost.
We recommend checking with your insurance company about potential discounts and requirements. Many homeowners discover that their policy offers savings for proactive earthquake preparedness measures like automatic gas shut-off valves.
Earthquake valves are calibrated to activate only during significant seismic events—typically magnitude 5.4 or higher. Small tremors and minor shaking won’t trigger the valve, so you don’t need to worry about false activations from everyday vibrations or minor earthquakes.
If your valve does activate, it means it detected potentially dangerous ground motion. The valve will remain closed until manually reset, which should only be done after a professional safety inspection. We can help you reset the valve and perform the necessary leak checks to ensure your gas system is safe.
Never attempt to reset an activated earthquake valve yourself. Gas line work requires licensed professionals who can properly test for leaks and ensure all connections are secure before restoring service to your home.
Most residential installations take 2-4 hours from start to finish. This includes temporarily shutting off your gas service, installing the valve and stabilizer brackets, testing the system, and restoring gas service to your home.
The timeline can vary depending on your specific setup. If your gas meter is easily accessible and your existing piping is straightforward, we can often complete the work more quickly. More complex installations involving difficult access or additional piping work may take longer.
We schedule installations at your convenience and work efficiently to minimize disruption to your daily routine. Once we’re finished, you’ll have a safety system that works automatically for years without any maintenance required on your part.
We strongly advise against DIY earthquake valve installation. Working with natural gas lines is extremely dangerous, and incorrect installation can create serious safety hazards including gas leaks, fires, or explosions.
California regulations require that only licensed professionals work on gas systems. The installation involves shutting off gas service, working with pressurized gas lines, and ensuring proper valve calibration—all tasks that require specialized training and experience.
Professional installation also ensures your valve meets all state requirements and local codes. We carry the proper insurance and licensing to work safely on gas systems, and our installation comes with warranties that protect your investment. The cost difference between professional and DIY installation isn’t worth the safety risks involved.
Yes, earthquake shut-off valves are completely mechanical devices that require no electrical power to operate. They use a motion-sensitive triggering mechanism with a steel ball and springs—no batteries, electricity, or external power sources needed.
This mechanical design is actually a key advantage. During major earthquakes, power outages are common, but your earthquake valve will still function exactly as designed. The valve detects ground motion through its internal mechanism and closes automatically regardless of whether your home has electricity.
Once activated, the valve remains closed until manually reset by a qualified professional. This ensures your gas supply stays safely shut off even during extended power outages that might follow a major seismic event. The mechanical operation makes these valves incredibly reliable when you need them most.
