What it is
The Worcester Bosch drain screw assembly, part number 87161200370, is a component used on a range of Worcester Bosch gas boilers. It seals the drain point on the appliance, allowing the system to be drained and refilled during servicing or repair. The assembly forms part of the boiler's water circuit and must seal correctly to prevent leaks.
Signs this part needs replacing
- Water weeping or dripping from the drain point
- Corrosion or scale build-up on the screw head or thread
- Rounded or damaged screw head that will not turn or seal cleanly
- Seal or washer no longer seating correctly after draining
- Persistent minor leak after the boiler has been drained and refilled
Before you order
- Confirm your boiler model against the fitment list above
- Check that the part number 87161200370 matches the one on your appliance or in the manufacturer's parts list
- Inspect the sealing washer or O-ring and replace if worn
- Have a suitable container and cloth ready, as draining will release water
