What it is
The Pipe (Pressure Relief Valve) is a Worcester Bosch component supplied under part number 8737605695. It forms part of the pressure relief valve arrangement on Greenstar 1000 Series combi boilers, carrying water away from the valve body when the appliance discharges. It is a service part intended for like-for-like replacement on the boiler models listed below.
Signs this part needs replacing
- Water tracking or dripping from the pressure relief discharge pipe when the boiler is not firing
- Scale, corrosion or debris visible inside or around the pipe and valve outlet
- System pressure repeatedly dropping and needing regular top-ups
- Discharge pipework showing staining, crusting or pooled water at the outlet
- Visible damage, cracking or a poor seal where the pipe joins the valve assembly
Before you order
- Confirm the boiler model matches one of the Greenstar 1000 Series variants listed
- Check the existing part number on the component or in the appliance documentation against 8737605695
- Inspect the pressure relief valve itself, as the pipe and valve are often serviced together
- Verify the appliance GC number against the boiler data badge before fitting
