FAQs for gas piping projects in Duarte, CA

Building code requirements vary by location. In many earthquake-prone areas, seismic gas shut-off valves are mandatory for new construction and during certain renovations or property transfers. Local building codes may specify which valve models are approved for installation. 

Even where not required by law, these valves are strongly recommended as a safety measure in seismic zones to prevent gas-related fires and explosions following earthquakes.

Many insurance providers recognize the safety benefits of earthquake valves and may offer discounts on premiums. The specific savings depend on your insurance company's policies and your property's location. Contact your insurance provider directly to inquire about potential discounts for seismic safety improvements, as offerings vary between companies and regions.

Licensed natural gas plumbers are the most qualified professionals for earthquake valve installation. In most states, plumbers must maintain specific certifications and insurance coverage to work with gas lines. These professionals understand local building codes, proper valve placement, and how to ensure the system functions correctly during an emergency. Always verify that your installer has the appropriate licenses before proceeding with installation.

When an earthquake valve activates during a seismic event, it automatically shuts off the gas supply to your home. After the valve has triggered, you'll need a qualified professional to inspect your gas system for damage before resetting the valve and restoring gas flow. This safety measure prevents gas from flowing through potentially damaged pipes or into your home when appliances might have been compromised during the earthquake.
