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 gas 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.
