What it is
The Biasi BI1782107 is a condensate trap used across the Biasi condensing boiler range. It collects the condensate produced during combustion and holds a water seal that stops flue gases passing back into the appliance casing. It is a serviceable component, replaced when the trap becomes blocked, cracked or contaminated.
Signs this part needs replacing
- Water leaking from the trap body or surrounding condensate pipework
- Gurgling or bubbling noises from the boiler during operation
- Condensate backing up or overflowing from the trap
- Boiler locking out or displaying a condensate-related fault
- Visible cracks, discolouration or heavy sludge build-up inside the trap
Before you order
- Confirm your appliance model against the fitment list above
- Check the part number on the existing trap matches BI1782107
- Inspect the condensate pipework and sump for blockages before fitting the new trap
