What it is
The Worcester Bosch seal siphon top, part number 8716117064, is a replacement seal for the top of the condensate siphon assembly on Worcester Bosch Greenstar i ErP system boilers. It forms the airtight joint at the siphon top, keeping condensate contained and preventing water or flue gases from escaping past the connection. The seal is a service item, so it is replaced when the original has hardened, distorted or started to weep.
Signs this part needs replacing
- Condensate weeping or dripping from the top of the siphon assembly
- Damp patches, staining or water marks inside the boiler casing around the condensate trap
- A seal that has hardened, flattened, split or lost its shape when inspected
- The siphon top failing to seat squarely, leaving a joint that does not seal
- Recurring condensate trap faults traced back to a poor seal at the siphon top
