Frequently asked questions
Is an earthquake gas shutoff valve required by law in San Marcos?
While not universally mandated for all existing homes, new construction and significant renovations in San Marcos often require earthquake gas shutoff valves. It's highly recommended for all properties due to seismic risk.
How does an earthquake gas shutoff valve work?
The valve contains a seismic sensor or pendulum that is triggered by ground motion exceeding a certain threshold, automatically closing the gas flow to your property.
Will installing this valve affect my gas pressure or appliance performance?
No, a properly installed and sized earthquake gas shutoff valve should not negatively impact your gas pressure or the performance of your gas appliances.
How often do earthquake gas shutoff valves need maintenance?
Generally, these valves are designed to be maintenance-free. However, it's a good practice to visually inspect them during routine plumbing checks to ensure they are free from damage or obstruction.
