In Atlanta, a water heater is crucial, especially during the winter. At Greenlee Plumbing Inc., we receive lots of questions about how to extend the life of a water heater.
One of the best ways to do this is to install an expansion tank. This tank relieves some of the pressure on the heater itself and keeps it working efficiently for a much longer lifespan.
Pressure relief valves accomplish the same thing by further regulating the water pressure. These valves are not required for the expansion tank to work, but they do help share the load by regulating the water pressure.
What a lot of people don't realize is that in specific states, plumbing codes require that a pressure relief valve be installed at the same time as expansion tanks. For example, Georgia has very specific pressure requirements. Our team is always up to date on the transitions of new codes and we assure you all regulations will be met. Reach out to us if you live in a multi-family home or own an apartment. Our services cater to every home. Rely on Greenlee Plumbing, Inc. to handle all of your Atlanta expansion tanks and valves services.

What is the Georgia state requirement regarding this?
The state of Georgia states, in Section 607.3.2 of the Plumbing Code, that "if a system with a water heater has a backflow prevention device installed and as a result thermal expansion causes an increase in pressure, a device must be fitted to limit the pressure to 80 pounds per square inch (psi) or less."
This backflow prevention device is the expansion tank, and the pressure-limiting device is a pressure valve. These two things are sold and installed separately, but the Georgia code requires both.
When will you need replacement?
To keep your expansion tank and pressure relief valve working properly, be watchful of any signs that they need replacement. There are four common signs that indicate replacement:
1. The pressure of the diaphragm inside the expansion tank is too low. This allows for the water from the heater to flow freely as the diaphragm is not functioning to limit the amount of water flowing into the expansion tank. You should check this pressure monthly with a pressure gauge.
2. The expansion tank is leaking or full.
3. There is no air pressure in the tank. Check this with an air gauge. Air can be pumped in, but that is a temporary fix. It is better to just replace the tank.
4. Pressure from the pressure regulating valve exceeds 80 psi. This indicates a faulty valve as it is not performing its only function.
