What it is

The flue to cast sump seal is a sealing component for Andrews water heaters, supplied under part number 7706835. It sits at the joint between the flue outlet and the cast sump, sealing that connection on the Neoflo SC25 range. The seal is a service item that is renewed when the flue connection is disturbed or when the existing seal has degraded.

Signs this part needs replacing

  • Visible cracking, hardening or flattening of the seal material
  • Soot staining or discolouration around the flue-to-sump joint
  • Condensate or water weeping at the joint
  • Flue gas or combustion odour detected near the connection
  • Seal displaced or deformed after flue servicing

Before you order

  • Confirm your appliance model and part number against the manufacturer's parts list
  • Check that the seal is the flue-to-cast-sump item on your unit
  • Inspect the flue and sump mating surfaces for damage before fitting
  • Consider whether other seals in the flue assembly also need renewing
