As water heats and expands, the vessel absorbs excess pressure, preventing stress on internal components, reducing the risk of leaks, and ensuring consistent hot water performance.\u003c\/p\u003e\n\u003cp data-start=\"553\" data-end=\"821\"\u003eA failing or waterlogged expansion vessel can cause pressure fluctuations, dripping from the PRV, reduced hot water flow, or intermittent boiler operation.
