What it is

The Heatrae Sadia Isolation Valve 3/4" BSP Male/Male (Red) is a service valve used to isolate the water connection on Heatrae Sadia HI-MAX Store unvented hot water cylinders. It has a 3/4" BSP male thread at each end, allowing it to sit inline between the cylinder connection and the pipework. The valve is supplied in red.

Signs this part needs replacing

  • The valve body or spindle is weeping when in the open position
  • The handle turns but does not shut off the flow of water
  • Visible corrosion or scale build-up around the threaded connections
  • The valve will not operate freely, making isolation of the cylinder difficult

Before you order

  • Confirm the cylinder model is a HI-MAX Store unit and that 3/4" BSP male threads match both mating connections
  • Check the thread form and orientation on the existing valve before removal
  • Isolate and drain the relevant section of the system before fitting
