Backflow Prevention Thermal Expansion
In order to maintain the excellent water quality we have here in Cobb, the Cobb County Water System recommends the use of a thermal expansion tank in conjunction with the backflow prevention device creating a closed system. The thermal expansion tank is a simple and efficient method to ensure that your system is safe.
Our goal is to be good stewards of our greatest natural resource, water. The thermal expansion tank is just one way you can help us conserve water and preserve its quality.
Thermal expansion tanks can be installed by your local plumber, or there are do-it-yourself kits available from your local hardware store. These kits come with a full set of simple instructions, and many come with all the tools needed for installation.
If the do-it-yourself installation is not right for you, simply call your local plumber for assistance. A licensed plumber should be able to take care of your thermal expansion needs. This will enable worry-free installation of your device, according to code.
