What it is
The Worcester Bosch 87161138350 is a siphon supplied for the Greenstar RI range of condensing gas boilers. It forms part of the condensate trap assembly, collecting condensate produced during combustion and discharging it in controlled amounts to the drain. The siphon prevents flue gases from passing back through the condensate route.
Signs this part needs replacing
- Water leaking from the condensate trap or the pipework beneath the boiler
- Gurgling or bubbling noises from the condensate route during operation
- Boiler locking out or showing a condensate-related fault code
- Visible cracks, distortion or heavy scale build-up on the siphon body
- Standing water or residue collecting around the trap instead of draining away
Before you order
- Confirm your boiler model against the fitment list above, including the NG or LPG variant
- Check the part number on the existing siphon matches 87161138350
- Verify whether your appliance is a standard, ErP or ErP+ build
- Inspect the surrounding condensate pipework and seals for damage before fitting
