What it is
The CONNECTING PIPE (PRESSURE RELIEF VALVE) is a Worcester Bosch pipe component that links the pressure relief valve into the boiler's hydraulic circuit on the Greenstar 4000 System range. It carries water from the relief valve assembly and forms part of the boiler's pressure control and discharge path. The part is identified by Worcester Bosch part number 8737602347.
Signs this part needs replacing
- Water weeping or tracking from the pipe joints around the pressure relief valve
- Visible corrosion, scaling or pitting on the pipe surface or at the connection ends
- The pressure relief valve discharging continuously, with the pipe unable to seal at the valve outlet
- System pressure repeatedly dropping or rising without an obvious cause elsewhere in the circuit
- Damp staining or mineral residue below the relief valve discharge area
Before you order
- Confirm the boiler model against the fit list above before ordering.
- Check the Worcester Bosch part number 8737602347 matches the number on the existing pipe or the boiler's parts list.
- Establish whether the appliance is the NG or LPG variant, as both appear in this fitment range.
- Inspect the pressure relief valve and its seals at the same time, since a leaking pipe connection often accompanies a tired valve.
