What it is
The Glow-worm 0020018576 is a flexible hose that connects the expansion vessel within the boiler. It carries system water between the vessel and the hydraulic circuit, absorbing movement and vibration in the connection. It is used on Glow-worm BG330 PLUS and Xtramax HE boiler models.
Signs this part needs replacing
- Water weeping or dripping from the hose or its crimped end fittings
- Visible corrosion, cracking or perishing on the hose body
- System pressure dropping repeatedly with no other obvious cause
- Kinking, flattening or blockage restricting flow to the expansion vessel
- Water staining or scale deposits around the hose connections
Before you order
- Confirm your boiler model against the fitment list above
- Check the part number on the existing hose or in the manufacturer's parts list
- Inspect the connection points at both ends for damage before fitting
- Verify the expansion vessel itself is sound, as a failed vessel can mimic a hose fault
