herokee county has joined the ranks of many other Metro-Atlanta water companies by improving the infrastructure of our water systems. Many Cherokee residents have been receiving letters from Cherokee County Sewer and Water Authority informing them that they will be installing new backflow prevention devices in their area. The letter further recommends that all residents bring their homes up to present code by installing a thermal expansion device to create a closed system. The thermal expansion tank is a simple and efficient method to ensure that your system is safe.
What is Thermal Expansion?
Thermal expansion refers to the characteristic of water to expand when heated and contract when cooled. Unlike air, which can be compressed, water grows in volume and must be accommodated when heated.
Why is Thermal Expansion Occurring?
In a water heater, thermal expansion can create more pressure than the system can handle. When unchecked, this pressure can result in expensive leaks, as well as damage to the water heater, pipes, or other plumbing fixtures.
When is a Thermal Expansion Device Necessary?
- A recent water meter replacement
- A water heater replacement
- The construction of a new home
