What it is
The Worcester Bosch 87161023490 is a 15mm isolating valve supplied for Worcester Bosch combi and highflow appliances. It sits on the water circuit and lets an engineer shut the supply down locally, so the appliance can be drained or worked on without isolating the whole property. The valve is a serviceable component and is listed against a number of Worcester Bosch 24i RSF, 28i RSF and Highflow 400 variants.
Signs this part needs replacing
- The valve spindle is stiff or will not turn, so the supply cannot be shut off cleanly.
- Water weeps from the spindle gland when the valve is operated.
- A drip or stain appears at the compression nut or the valve body joint.
- The appliance cannot be isolated for a service or repair without draining the full system.
- Scale or debris in the valve seat prevents it closing fully.
Before you order
- Check the appliance model and GC number against the compatibility list before ordering, as several Worcester Bosch variants use different valve arrangements.
- Confirm the connection size required on your appliance is 15mm.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
