What it is
The Glow-worm hydraulic pressure relief valve, part number 0020086306, is a safety component used in the hydraulic circuit of Glow-worm Envirosorb air/water heat pumps. It opens to discharge excess system pressure, protecting the appliance and connected pipework from over-pressurisation. It is listed in the manufacturer's parts range under the pressure relief valve description.
Signs this part needs replacing
- Water weeping or dripping from the valve outlet when the system is at normal operating pressure
- System pressure repeatedly dropping and needing frequent top-ups
- Visible scale, corrosion or debris around the valve seat or outlet
- Valve failing to discharge when system pressure rises above the normal range
- Discharge pipework continually wet or showing staining from persistent passing
Before you order
- Confirm the appliance model against the fitment list above
- Check the part number on the existing valve or the manufacturer's parts list for your unit
- Verify the system pressure reading and confirm the fault lies with the valve rather than expansion vessel charge or filling loop
- Isolate and depressurise the appliance before removal and fitting
