What it is
The Worcester Bosch 87161134140 is a flexible hose that links the expansion vessel to the hydraulic circuit on Greenstore combi soft start appliances. It carries system water between the vessel and the boiler's internal pipework, letting the vessel absorb the volume change as the water heats and pressure rises. The hose is supplied as a direct replacement item for the Worcester Bosch models listed below.
Signs this part needs replacing
- System pressure falls repeatedly and the boiler needs topping up more often than normal
- Water weeping, dripping or leaving staining around the expansion vessel connection
- The hose shows cracking, perishing, hardening or bulging when inspected
- Water discharging from the pressure relief valve because the vessel can no longer absorb expansion
- Rapid pressure swings or kettling during a heating cycle
Before you order
- Confirm the appliance model and serial number against the compatibility list before ordering.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
- Inspect the connection at the vessel stub and the hose routing when the old hose is removed.
