What does an expansion tank do?
It absorbs the expansion of water as it heats up, preventing excessive pressure in the boiler system.
How long do expansion tanks last?
Typically 5–10 years. The diaphragm can fail over time, causing it to lose its air charge.
Can a failed expansion tank damage my boiler?
Yes — it can cause repeated pressure surges, relief valve failure, and unnecessary stress on the heat exchanger.
