Earthquake Shut-Off Valve Cost Breakdown

Your earthquake valve cost will include the price of the valve itself plus the labor to install it. Some cities require an inspection as well, which could add extra costs.

Profession Installation

The professional labor required to install an earthquake valve usually ranges from $150 to $200. Complex installations, such as having a difficult-to-access gas meter, could drive up this cost.

Seismic Shut-Off Valve Cost

Earthquake valves can go for about $100 to $300 depending on the pipe’s size and pressure capacity.

Natural Gas Line Inspections

The city may require an inspection in some areas, which can cost anywhere between $40 and $150. Some cities will include this cost in their fees, while others require the homeowner to cover it. In any case, getting your valve and gas lines inspected is always a wise gas line service cost to invest in. 

What Factors Influence Your Cost to Install a Seismic Shut-Off Valve?

Most standard earthquake valve installations will cost around $350, but certain factors could increase your costs. These include:

  • Varying labor prices

  • Difficult-to-access gas meters

  • Having more than one gas meter

  • Requiring extra gas piping

  • Having lines for multiple households on a single gas meter

Frequently Asked Questions

Anyone living where earthquakes occur should get one, regardless of whether the city requires it. A seismic shut-off valve will automatically cut off the flow of gas, which could prevent fires and explosions in the event of an earthquake.
