What it is

The Alpha 1.018148 is a tundish used on Alpha gas boilers and Alpha Solar Smart unvented cylinder installations. It provides a visible air gap in the discharge pipework, allowing water from a pressure relief valve to be seen and safely directed to a drain. It is listed as a spare component for the Alpha appliance families below.

Signs this part needs replacing

  • Scale or debris visible inside the tundish, restricting flow
  • Water overflowing or spilling from the tundish instead of running to the drain
  • Dripping or weeping at the tundish connections
  • Cracks or physical damage to the body
  • Discharge water not visible through the air gap when a relief valve operates

Before you order

  • Confirm your appliance model appears in the fitment list above
  • Check the part number 1.018148 against the manufacturer's parts list for your appliance
  • Inspect the existing tundish and pipework to confirm the fault lies with the tundish rather than a blocked drain or a faulty relief valve
