What it is
The Grant diverter valve MPCBS20/A is a hydraulic component used in Grant combi appliances. It sits in the water circuit and directs flow between the domestic hot water and heating sides of the boiler, so the appliance delivers hot water on demand and switches back to heating without cross-flow. It is supplied as a Grant Spares part and is listed under the diverter and motorised valve group.
Signs this part needs replacing

- The valve head does not move or is slow to change position between heating and hot water
- Domestic hot water temperature drops when another outlet is used
- Water weeping from the valve body or around the actuator head
