What it is

The Andrews 7705044 is a combined pressure reducing, check and expansion valve with a 1 inch connection. It is used on Andrews water heaters in the Hiflo EVO range, where it regulates incoming supply pressure, prevents backflow through the supply pipework and provides expansion control within the same valve body.

Signs this part needs replacing

  • Outlet pressure at the heater creeps up or fluctuates instead of holding steady
  • Water passes back through the valve when the supply is isolated
  • Discharge from the expansion relief, indicating the valve is not holding pressure
  • Weeping or visible leaks from the valve body or its connections
  • Downstream pressure readings rise above the level the valve is set to

Before you order

  • Confirm your appliance model against the fit list above
  • Check that the existing valve connection is 1 inch
  • Note the valve orientation and pipework layout before removal
  • Consult the manufacturer's parts list if your model is not listed
