What it is

The Worcester Bosch condensate drain pipe (part 87186829130) is a replacement pipe for the condensate side of the boiler. It carries acidic condensate water produced during combustion away from the heat exchanger and into the trap and discharge route. It is a Worcester Bosch spare listed under condensate traps and siphons, and it is used across the Greenstar Ri ErP Compact range.

Signs this part needs replacing

  • Water pooling beneath the boiler or inside the casing around the condensate route
  • Dripping or a visible weep from the pipe, its joints or the trap connection
  • Boiler locking out or shutting down because condensate cannot drain away
  • Cracking, splitting or heavy discolouration on the pipe wall
  • Condensate backing up in the trap and overflowing during operation

Before you order

  • Check the GC number and serial plate on the appliance to confirm the model before ordering.
  • Compare the part number on the existing pipe with 87186829130 to make sure it matches.
  • Inspect the trap and any seals at the same time, as these are often disturbed when the pipe is removed.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
