What it is

The RETAINER, EV BOTTOM FLANGE is a Glow-worm component that secures the bottom flange of the expansion vessel. It is fitted to Glow-worm Compact and Micracom combi boilers and holds the flange in its correct seated position within the vessel assembly. The part is supplied under Glow-worm part number 0010028834.

Signs this part needs replacing

  • The expansion vessel flange is loose or not held squarely in position
  • Water weeping or staining around the base of the expansion vessel
  • The vessel moves or shifts when the boiler is running
  • The retainer is corroded, cracked or deformed on inspection

Before you order

  • Confirm the boiler model against the fit list above
  • Check the GC number on the appliance data badge where applicable
  • Inspect the existing retainer and flange seating before ordering
  • Check the expansion vessel itself for corrosion or loss of charge, as the retainer alone will not correct a failed vessel
