What it is
The Johnson & Starley temperature and pressure relief valve is a safety component fitted to State SBE and SBT boilers. It opens to discharge water if system temperature or pressure exceeds safe limits, protecting the appliance and the heating circuit. It is supplied under part number S00707.
Signs this part needs replacing
- Water weeping or discharging continuously from the valve outlet
- The valve fails to seat fully after it has operated
- System pressure rises beyond normal working range without the valve relieving
- Scale, corrosion or debris visible around the valve body or seat
- Boiler locking out or discharging repeatedly during heat-up
Before you order
- Confirm the appliance model and serial number against the manufacturer's parts list
- Check the existing valve's part number and pressure rating before ordering
- Verify the expansion vessel and system charge pressure are correct, as a failed vessel can mimic valve failure
- Isolate the appliance, drain down and depressurise before fitting
