What it is
The hydraulic group assembly is a manufacturer part (720957201) for the Potterton Apollo 30 boiler. It forms the water-side hydraulic section of the appliance, handling the flow and pressure path through the boiler. The supplier listing identifies it as the 30 kW, 12 litre variant.
Signs this part needs replacing

- Domestic hot water temperature is inconsistent, or the boiler does not switch cleanly between heating and hot water.
- System pressure falls repeatedly, or the pressure reading becomes erratic.
- Water is visible around the hydraulic block or the components mounted to it.
- The boiler runs noisily, with banging or kettling from the hydraulic section.
