What it is

The Worcester Bosch 87161410520 is a flow regulator with adaptor, supplied in white and rated at 8 litres. It governs the direction and rate of water through the hydraulic circuit of the appliance, and in some installations acts as a check valve to stop fluid drifting into zones where it does not belong. It is a Worcester Bosch hydraulic spare for the 24i RSF combi family.

Signs this part needs replacing

  • Reduced or inconsistent flow rate at hot water outlets
  • Water temperature fluctuating during draw-off
  • Scale or debris restricting the regulator
  • Leaks or weeping around the regulator body or adaptor
  • Flow passing in the wrong direction through the circuit

Before you order

  • Check the GC number and appliance serial plate to confirm the model matches the compatibility list.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
  • Confirm whether a new seal or gasket is needed when refitting the regulator.
