Excess Flow Valve
You may request that Powell Clinch Utility District (PCUD) install an excess flow valve (EFV) on the gas line to your property. EFVs are mechanical shut-off devices that can be installed in the gas pipe running to the gas meter at your property (the service line). An EFV is designed to shut off the flow of natural gas automatically if the ser-vice line breaks, for example, by excavation accident. Stopping the flow of gas from a broken service line significantly reduces the risk of natural gas fire, explosion, person-al injury, and/or property damage.
If you notified us that you want an EFV we will contact you to set up a mutually agree-able date when we will install an EFV on your service line. You will be billed $600 to cover the cost of installing the EFV.
EFVs are not designed to close if a leak occurs beyond the gas meter (on house piping or appliances). EFVs also my not close if the leak on the service line is small.
If you add additional gas appliances, for example, a pool heater, emergency generator, etc., the additional gas flow may cause the EFV to close. If the additional gas load exceeds the capacity of the EFV, replacement maybe necessary.
If it becomes necessary to maintain or replace the EFV on your service line we will maintain or replace the EFV at no charge to you.
EFVs cannot be installed on some service lines due to high gas flow, low pressure, or other factors. If you request an EFV we will inform you if your service line cannot accommodate an EFV.
For your safety always call 811 to have gas lines and other buried utilities marked before allowing anyone to dig in your yard.
