What it is
The Glow-worm hydraulic block (10 litre) is a diverter valve assembly used in the hydraulic circuit of Glow-worm gas boilers. It manages the changeover between domestic hot water and central heating operation within the appliance. This component is supplied under Glow-worm part number 0020118162.
Signs this part needs replacing
- No hot water produced when a domestic hot water tap is run
- Radiators heating up when only hot water is demanded
- Hot water temperature fluctuating or running cold during draw-off
- Diverter valve sticking, seized or failing to move between positions
- Water weeping or dripping from the hydraulic block body or its seals
Before you order
- Confirm your boiler model against the fitment list above before ordering
- Check the part number on the existing hydraulic block matches 0020118162
- Establish whether the fault lies with the hydraulic block or the diverter valve head, as these are separate components
- Work on the hydraulic circuit involves draining and refilling the appliance, so confirm the correct part before booking the job
