What it is
Hydraulic valves manufactured by Glow-worm for use in its combination boiler range. They form part of the boiler's hydraulic circuit, controlling the flow of water between the heating and domestic hot water sides of the appliance. The part is supplied under Glow-worm part number 0020195592.
Signs this part needs replacing
- Water weeping or visible staining around the valve body or its connections
- Loss of system pressure that cannot be traced to any other component
- Domestic hot water running cold or intermittent while the heating circuit behaves normally
- Heating circuit warming when only hot water is demanded, or vice versa
- Valve sticking or failing to seat, causing flow to continue when it should be shut off
Before you order
- Confirm the boiler model and GC number against the fitment list above
- Check the existing valve against the part number 0020195592 before ordering
- Establish how many valves are required for the repair, as the part is listed as a valve assembly
- Isolate and drain the appliance before removal, and check for any seals or washers needed on refit
