When water is heated, it expands—a process known as thermal expansion. In systems with a backflow preventer, this expanded water has nowhere to go, which can cause unwanted pressure buildup and trigger hot water tank relief valves. Expansion tanks are designed to absorb this excess pressure, protecting the system and maintaining safe operation.
