What it is
The Navien condensate trap is a boiler component fitted to the LCB 700 range. It collects condensate produced during combustion and provides a water seal that prevents flue gases from escaping into the appliance or the room. It is supplied as a serviceable part for the LCB 700 combi, regular and system models.
Signs this part needs replacing
- Water leaking from the trap body or its connections
- Water pooling beneath the boiler
- Gurgling or bubbling noises from the condensate route
- Boiler locking out or reporting a condensate or flue-related fault
- Visible cracks, distortion or heavy scale build-up in the trap
Before you order
- Confirm your appliance is an LCB 700 and note whether it is the internal or external variant
- Check the output rating of your boiler against the fit list
- Verify the model and serial number against the manufacturer's parts list for your appliance
- Inspect the existing trap and its connections before removal to confirm the fault lies with the trap itself
