Natural Gas Excess Flow Valves Available

Posted on Thursday, May 25, 2017

Cedar Falls Utilities started installing excess flow valves in 2010 on all new or replaced natural gas service lines that serve single family residential customers on our high pressure gas distribution system.

Certain residential and small commercial customers may now request the installation of an excess flow valve on their existing natural gas service lines if they are connected to the high pressure gas distribution system.

An excess flow valve is a safety device designed to significantly reduce the flow of natural gas in a damaged service line. The most common cause of damage is an excavation incident between the gas main and the meter.

The decreased flow of natural gas reduces the risk of personal injury and property damage that could occur if the escaping natural gas ignites.

However, an excess flow valve is not designed to protect against minor gas leaks, a leak occurring on the customer piping after the meter or a gas leak inside a home or business.

Customers connected to CFU’s high pressure gas system are eligible to add an excess flow valve. A map of the gas system is available at www.cfu.net/efv. Neighborhoods and streets in red on the map are on the high pressure system.

If you choose to add an excess flow valve to your service line, you will be charged $800 to cover the cost of installation. CFU will be responsible for the maintenance costs after the initial installation.

If you are interested in an excess flow valve installation or would like more information, please contact CFU’s Gas Service Department at 268-5340. If your natural gas service line meets the requirements for an excess flow valve, we will schedule the installation.
