What it is

The venturi is a Vaillant component used in the MAG Mini range of gas water heaters. It forms part of the appliance's water or gas circuit, where a narrowed passage creates the pressure differential needed to operate the associated control. It is supplied under Vaillant part number 115311.

Signs this part needs replacing

  • The appliance fails to fire or modulate correctly despite adequate water flow
  • Weak or inconsistent burner response when a tap is opened
  • Water heater cuts out or cycles during draw-off
  • Visible damage, blockage or debris in the venturi passage
  • Leaks or staining around the venturi housing

Before you order

  • Confirm the appliance model and year against the fitment list above
  • Check the existing venturi part number on the component or in the appliance documentation
  • Inspect the surrounding pipework and seals for damage before fitting
  • Verify that no other component in the circuit is causing the fault
