Worcester Bosch Flow Limiter Insert 14 Litre 87161078870

The Worcester Bosch 87161078870 is a flow limiter insert rated at 14 litres, used to regulate the flow of water through the appliance so the boiler delivers a stable, predictable draw-off rate. It sits within the water circuit of Worcester Bosch Greenstar CDi combi models and is classed as a flow regulator and governor spare. The insert is a small but functional component: once it becomes restricted or worn, the appliance can no longer hold its designed flow rate.

• Domestic hot water flow rate drops below the expected level at the tap or shower
• Flow rate becomes inconsistent between draw-offs, with the boiler unable to hold a steady output
• Scale, debris or sediment build-up visible on or around the insert
• Poor hot water performance at outlets that previously ran correctly
• Flow measured at the inlet falls outside the appliance's specified tolerance

• Check the GC number and appliance serial plate against the compatibility list to confirm the correct variant for your model
• Confirm the alternative part number 1015299 matches the part currently fitted
• Inspect any seal or gasket at the fitting point and replace it if it is compressed or perished
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
