What it is
The Heatrae Sadia 5136203 is a blue isolation valve with 3/4" BSP male/male threaded connections. It is used on HI-MAX Store unvented hot water cylinders to isolate the water supply at the cylinder connection. The valve allows the cylinder or associated pipework to be worked on without draining the wider system.
Signs this part needs replacing
- Water weeping from the valve spindle when the handle is turned
- Valve does not shut off fully, allowing water to pass when closed
- Handle or spindle seized, stiff or rounded
- Leaks at either male threaded connection
- Visible scale or corrosion around the valve body
Before you order
- Confirm the thread size and type at the connection is 3/4" BSP male
- Check the cylinder model against the HI-MAX Store list above
