What it is
The Glow-worm 0020211445 is a domestic hot water (DHW) service valve for the Easicom, Essential, HOME and Sustain boiler families. It is fitted on the hot water circuit and provides a means of isolating that side of the appliance during servicing or component replacement. It is classed as an isolation valve within the boiler's hot water assembly.
Signs this part needs replacing
- Water weeping or dripping from the valve body or spindle
- Damp staining or scale deposits around the valve on the DHW pipework
- The isolation screw will not turn, or turns without shutting off the flow
- Water continues to pass through the valve when it is closed, preventing proper isolation
- Corrosion or pitting on the valve body
Before you order
- Confirm your boiler model against the fitment list above
- Check the GC number on the appliance data badge where one is listed
- Inspect the valve and surrounding pipework to confirm the fault is at the valve and not a joint or seal
- Confirm whether the hot water circuit can be safely isolated and drained before work begins
