What it is
The Viessmann P-TRAP is a condensate trap (siphon) used on Vitodens 100-W gas boilers. It sits on the condensate path from the appliance, holding a water seal that allows condensate to drain away while preventing flue gases from escaping. It is listed under Viessmann siphon reference 7829786.
Signs this part needs replacing
- Water or condensate leaking from around the trap or boiler casing
- The trap no longer holds its water seal, allowing flue gases to pass
- Visible cracks, splits or brittle, discoloured plastic on the trap body
- Sludge or debris building up inside the trap and restricting flow
- Condensate faults, gurgling or lockouts linked to the trap
Before you order
- Confirm the boiler model against the fit list above
- Check the appliance serial number against the corresponding entry
- Verify the existing trap is the siphon type fitted to WB1B and WB1BC models
- Inspect the condensate pipework and connections for damage before refitting
