Backflow Prevention/ Meter Change-out Letters
For the past several years, Columbus Water Works (CWW) has been diligently working to replace residential water meters that have reached the end of their useful life.  In accordance with State and Federal requirements, the new residential meters (5/8-inch) being installed include a built-in backflow prevention device.  This device prevents water from re-entering the public water system once it passes the meter.  These devices may cause a slight change in the water pressure in your home and create a “closed” system that may produce plumbing issues due to thermal expansion.  For more information on Backflow Prevention please click here.

In an effort to reduce plumbing issues and costly plumbing adjustments, CWW has created a Thermal Expansion Device (TED).  This device connects to your washing machine’s cold water connection and provides a release for excess pressure.  CWW provides these devices to our customers for $25.  (This is the exact cost we pay to produce each device.)  Although a TED device is not the only option for home owners to address thermal expansion; however, it is the only option provided by CWW.  If you are interested in purchasing a TED, please come to our office at 1421 Veterans Parkway Monday through Friday between 9 am and 5 pm.  A customer service representative will be able to assist you.

If your property is scheduled to have the water meter replaced, CWW will mail out a certified letter to the billing address on file. The letters are mailed several months in advance to allow property owners the opportunity to prepare for these changes.  Each certified letter includes an informational pamphlet explaining thermal expansion and our office contact number if you have additional questions or concerns. To view a copy of the pamphlet included in each certified letter, please click here.

If someone is not available to sign for the certified letter, post office will leave notification for the addressee. If you receive this notification, it is important that you pick up the letter and review the information provided.
