What it is

The Alpha condensate drain manifold seal (part number 1.021971) is a sealing component for the condensate drainage system on Alpha gas boilers. It sits within the condensate drain manifold to prevent water escaping from the trap and drainage path. This seal is used on Alpha He25 and He33 LPG models.

Signs this part needs replacing

  • Water leaking from the condensate trap or manifold area
  • Visible hardening, cracking or distortion of the seal
  • Condensate pooling around the boiler casing or floor
  • Damp patches or corrosion near the condensate drainage path
  • Boiler lockout linked to a blocked or leaking condensate system

Before you order

  • Confirm your boiler model is Alpha He25 (LPG) or Alpha He33 (LPG)
  • Check the existing seal and manifold seating for damage or debris
  • Verify the part number 1.021971 against the manufacturer's parts list
  • Note that this seal is listed for LPG variants only
