What it is
The PRESSURE RELIEF VALVE (3-BAR) is a safety component for Potterton Commercial boilers, supplied under part number 5139807. It opens to discharge water when system pressure exceeds its set rating, protecting the appliance and its associated pipework from over-pressure. It is fitted to the Potterton Commercial IHE range.
Signs this part needs replacing
- Water continually dripping or running from the pressure relief discharge pipe with the system at normal pressure.
- System pressure rising during heating cycles and failing to settle back to its cold fill value.
- The valve body or outlet weeping, or showing scale and corrosion deposits around the seat.
- Boiler losing pressure repeatedly after topping up, with no visible leak elsewhere on the system.
- The valve failing to reseat after it has lifted, leaving the discharge pipe permanently wet.
Before you order
- Confirm the appliance model is a Potterton Commercial IHE 100/300 or IHE 150/300.
- Check the valve rating required by the installation matches the rating stated on the part.
- Verify the part number 5139807 against the existing component or the appliance documentation.
- Check the valve connection and outlet arrangement against the pipework on the appliance before removal.
