What it is
The Worcester Bosch 87161424220 is a pressure relief valve supplied as a spare for the Greenstar Camray range. It is mounted on the boiler's heating circuit and opens at its set pressure to discharge excess water away from the heat exchanger and other system components. The valve protects the appliance from over-pressurisation caused by expansion, blockage or a faulty expansion vessel.
Signs this part needs replacing
- Water discharging continuously from the pressure relief discharge pipe
- System pressure falling repeatedly and needing regular top-ups
- Weeping, dripping or scale staining around the valve outlet
- Boiler locking out or displaying a low pressure fault
- Valve failing to reseat after the system has been drained and refilled
