What it is

The 3.012752 is a diverter valve assembly for Alpha combi boilers. It is the component that directs hot water either to the central heating circuit (radiators) or to the domestic hot water circuit (taps and showers) depending on demand.

Signs this part needs replacing

  • No hot water, or heating only, but not both
  • Radiators stay lukewarm while a tap is running (cross-flow)
  • Valve stuck open or failing to switch over
  • Water leaking from the valve body
  • Knocking or banging noise as the valve switches

Before you order

  • Match the part number against your existing valve
  • Isolate the water and electrical supply before removal
  • Drain the system before disconnecting the valve
  • Fitting must be carried out by a Gas Safe registered engineer
