What an expansion tank does
A thermal expansion tank helps accommodate pressure changes as water heats in certain closed plumbing systems. It must be selected, installed and charged correctly for the system conditions.
Signs to investigate
Visible corrosion, leakage, unusual pressure behavior or a failed pressure test can justify inspection. These signs do not prove the expansion tank is the only cause; system pressure and related valves also matter.
Repair or replacement
A contractor can test the expansion tank and related pressure controls to determine whether adjustment, repair elsewhere in the system, or tank replacement is appropriate. Do not bypass pressure relief equipment.
Frequently asked questions
Does every home need an expansion tank? Requirements depend on plumbing configuration, local code and system design. Can a water heater expansion tank be replaced alone? Often, but it should be sized and checked in context of the complete water system.
