​​​​Excess Flow Valves​

​An optional device for some CenterPoint Energy customers​​

CenterPoint Energy can install excess flow valves on your home’s natural gas service line (the underground line that runs from the main line to the meter). 

  • Excess flow valves significantly reduce or completely shut off the flow of natural gas if a natural ga​​s service line becomes damaged. However, they do not protect against leaks beyond the meter assembly (house piping). 

  • When activated, an excess flow valve may prevent the buildup of natural gas and lessen the possibility of a natural gas fire, explosion, personal injury and/or property damage.

  • The average cost to CenterPoint Energy customers requesting the excess flow valve installation is expected to be $800, but the installation cost will vary from house to house, depending on the difficulty of installation. 

  • Due to operating characteristics and limitations, in some instances, excess flow valves cannot be installed. Each situation will be evaluated upon request.
