What it is

The Baxi 5110546 is a flow/return valve for the central heating circuit on selected Baxi 100HE Plus and Combi HE Plus boilers. It sits on the appliance pipework and allows the heating circuit to be isolated for servicing or component replacement. It is listed as an isolation valve within the Baxi spares range.

Signs this part needs replacing

  • Water weeping or dripping from the valve body or spindle
  • The valve handle will not turn, or turns without isolating the circuit
  • Scale or corrosion visible around the valve and its connections
  • Difficulty isolating the heating circuit during servicing
  • Persistent water loss or pressure drop traced to the valve

Before you order

  • Confirm your appliance model against the fitment list above
  • Check the GC number on your boiler's data badge matches the appliance you are working on
  • Confirm whether the fault is with the flow/return valve rather than an adjacent connection or pipework
  • Check the valve connections and orientation on your appliance before ordering
