A properly functioning expansion vessel accommodates water influx as pressure rises and releases it as the temperature, and consequently the pressure, drops.

These systems slowly pump hot water through your hot water pipes and back to the water heater through either a dedicated line or through the cold water line.

If you notice that the PRV leaks water, especially during water heating, it likely indicates that your expansion vessel is faulty or requires repressurization.

Pressure Relief Valves (PRVs) are crucial components in maintaining the safety and efficiency of a central heating system. PRV’s are designed to release water and reduce pressure, thus preventing potential damage.

Corrosion, material degradation, or high pressure can lead to a malfunctioning PRV, often indicated by leaking water or a hiss sound.

A Pressure Relief Valve regulates pressure to prevent damage to pipes, the boiler, and the entire central heating system. The PRV is connected to a discharge pipe that directs the expelled water safely away.
