What it is
The Worcester Bosch drain cock elbow, part number 87186855580, is a drain valve component used on Greenstar Ri ErP Compact appliances. It sits on the appliance's water circuit and provides a controlled point at which the system can be drained down during servicing, repair or decommissioning. As a Worcester Bosch spare, it is shaped and threaded to match the connection points on the relevant Greenstar models.
Signs this part needs replacing
- Water weeping or dripping from the drain point when the appliance is running or pressurised.
- A drain cock that will not seal fully after being closed, leaving a persistent drip.
- Stiff, seized or rounded operating head that cannot be turned by hand or spanner.
- Corrosion, scale build-up or staining around the elbow body or its threaded connection.
- Difficulty draining the system down because the outlet is blocked or the valve no longer opens.
Before you order
- Check the appliance GC number and model against the compatibility list to confirm the elbow matches your unit.

- Note the alternative part number 1031217, which may appear on older documentation or stock records.
