The City of Hesston is offering its customers the installation of an Excess Flow Valve (EFV) to the gas yard line to your property.
What an EFV will do
EFVs are mechanical shut-off devices that can be installed in the gas pipe running to the gas meter at your property. An EFV is designed to stop the flow of gas if the service line is broken, for example, by an excavation accident. Stopping flow of gas from a broken service line significantly reduce the risk of natural gas fire, explosion, personal injury and or property damage.
What an EFV won’t do
They are not designed to close if a leak occurs beyond the gas meter, on house piping or appliances. EFVs also may not close if the leak on the service line is small. There is also a possibility of closure if additional gas appliances, for example a pool heater, emergency generator, etc., the additional gas flow may cause the EFV to close.
