What it is

The Glow-worm 0020010154 is a temperature and pressure relief valve used on Glow-worm unvented storage cylinders and solar thermal installations. It opens to discharge water when system temperature or pressure exceeds safe operating limits, protecting the cylinder and associated pipework. It sits within the pressure relief and safety valve group of Glow-worm cylinder spares.

Signs this part needs replacing

  • Water continually discharging from the valve outlet or discharge pipe when the cylinder is at normal temperature and pressure
  • The valve dripping or weeping after it has operated, indicating it is not reseating
  • Visible scale, corrosion or debris around the valve seat or outlet
  • Discharge occurring during normal heating cycles rather than only under fault conditions
  • The valve lever failing to operate or return freely when tested

Before you order

  • Confirm your cylinder or solar model against the fitment list above
  • Check the existing valve and its labelling to confirm the part number 0020010154 is the correct item
  • Isolate the cylinder, depressurise the system and allow it to cool before removal
  • Verify the discharge pipework is correctly routed and undamaged before fitting the new valve
