The Worcester Bosch 87182256360 CDi Siphon is a genuine replacement condensate handling component designed to safely collect and discharge the acidic condensate produced during normal operation of condensing boilers. As combustion gases cool in the heat exchanger and flue, water vapour condenses and must be directed away from internal parts to prevent corrosion and pressure faults. The siphon creates a water seal that prevents flue gases or odours from entering the boiler room while allowing this condensate to flow smoothly into the drainage system.

This CDi siphon is compatible with Worcester Bosch CDi series boilers that reference part number 87182256360 in their technical documentation. To ensure correct fitment and reliable operation, always check that the part number on your existing siphon matches before installation, as condensate components and connection sizes can vary between models.

Supplied ready for direct replacement, the 87182256360 CDi Siphon connects to the boiler’s condensate outlet and drainage pipework without modification when installed by a qualified engineer. Choosing this genuine Worcester Bosch component helps restore effective condensate management, supports safe, efficient boiler performance and contributes to reduced risk of blockages, leaks or pressure faults in compatible CDi boilers.
