What it is

The 3-way valve complete cartridge is a diverter valve assembly component used in Alpha InTEC 50CS boilers. It controls the flow of heated water between the central heating circuit and the domestic hot water circuit. The cartridge is supplied as a complete unit, so the internal moving parts are renewed as one assembly rather than individually.

Signs this part needs replacing

  • No hot water while the heating continues to run normally
  • Heating warms up when only hot water is demanded, or hot water runs warm when only heating is called
  • The valve head or motor turns but the diverter does not change position
  • Stiff, sticking or jammed movement in the valve spindle
  • Water weeping from around the valve body or cartridge housing

Before you order

  • Confirm the boiler model is the Alpha InTEC 50CS
  • Check the existing valve body and motor are sound before renewing the cartridge alone
  • Isolate the boiler and drain down as required before fitting
  • Verify the part number 3.013730 against the appliance's parts list
