What it is

The Vokera 1791 is a double non return valve used on Vokera Linea 24 Mk1 and Linea 28 Mk1 gas boilers. It forms part of the appliance's isolation valve group and keeps flow through the pipework it serves travelling in one direction only.

Signs this part needs replacing

  • Flow passing in the wrong direction through the valve
  • Cross contamination between the heating and domestic hot water circuits
  • Pressure or air faults traced back to the valve not seating correctly
  • Scale or system debris holding the valve open
  • Weeping or visible leakage at the valve body or its connections

Before you order

  • Confirm the boiler is a Linea 24 Mk1 or Linea 28 Mk1
  • Check the appliance serial number falls within the range shown for your model
  • Verify the fitted valve is marked 1791 or matches the item being replaced
  • Check pipework connections and valve orientation before removal
