What it is
The HRM COM423 is a diverter service kit from HRM, supplied for work on gas boiler diverter valves. It is intended for servicing the diverter valve assembly, which directs water between the heating circuit and the domestic hot water circuit on a combi boiler. The kit carries the manufacturer part number COM423.
Before you order
- Confirm the part number COM423 matches the diverter valve currently fitted before ordering.
- Check the boiler make and model against your service documentation to confirm the kit is the correct one for the valve in question.
- Inspect the existing diverter valve for wear or scale before deciding whether a service kit or a complete valve assembly is needed.
