Vaillant Condense Trap VAILLANT011504

The Vaillant 011504 is a condense trap, the component fitted on the condensate path of a condensing boiler. It collects the acidic water produced as flue gases cool, holds a water seal that prevents combustion gases escaping into the room, and discharges the condensate to the drainage system.

It is supplied by Vaillant as a replacement part for their condensing appliance range. The trap is a serviceable item: once the seal is lost, cracked or blocked with scale and debris, condensate can back up or leak, so the trap is replaced rather than repaired.

• Water pooling or damp patches beneath the boiler or around the condensate pipework.
• Condensate overflowing from the trap, dripping from the casing or staining the wall.
• Boiler locking out or displaying a fault code linked to condensate removal.
• Gurgling, bubbling or slurping noises from the condensate route during operation.
• Cracks, heavy scale build-up or discolouration visible on the trap body or its connections.

• Check the appliance model and GC number against the compatibility information for your boiler.
• Confirm the part number on the existing trap matches 011504 before ordering.
• Inspect the condensate pipework, seals and connections while the trap is removed, and replace any perished seals at the same time.
• Allow the appliance to cool and isolate it before working on the condensate path.
