What it is

The R300 condensate drain is a condensate trap component for Andrews water heaters. It is supplied by Andrews Water Heaters under part number E355 and sits within the appliance's condensate drainage path. Its function is to collect and discharge condensate produced during combustion while preventing flue gases from escaping through the drain line.

Signs this part needs replacing

  • Water pooling or dripping around the condensate trap or its connections
  • Visible cracks, splits or physical damage to the trap body
  • Condensate backing up or failing to drain away from the appliance
  • Corrosion or degraded seals at the trap joints
  • Boiler lockout or fault indication linked to condensate removal

Before you order

  • Confirm the appliance model and serial number against the manufacturer's parts list
  • Check that part number E355 matches the trap currently fitted
  • Inspect the existing trap and drain line for blockage or damage before replacing
  • Confirm there is clear access to the trap and its connections on the appliance
