What it is
The Glow-worm 0020010153 is a pressure relief valve used on Glow-worm unvented storage cylinders and solar thermal installations. It opens to discharge excess pressure from the cylinder or system, protecting the vessel and connected components from over-pressurisation. It sits within the pressure relief and safety valve group of Glow-worm cylinder spares.
Signs this part needs replacing
- Water continually weeping or dripping from the discharge pipe with the system at normal operating pressure
- The valve fails to reseat after a pressure release and keeps passing water
- System pressure drops repeatedly and requires frequent topping up
- Visible scale, corrosion or debris around the valve seat or outlet
- Discharge pipe runs warm or wet when no over-pressure event has occurred
Before you order
- Confirm your appliance model against the fit list above
- Check the part number on the existing valve or in the manufacturer's parts list for your cylinder
- Verify the valve's pressure rating matches the specification for your cylinder before fitting
- Inspect the discharge pipework and expansion arrangement at the same time, as faults there can mimic a failed valve
