Heatrae Sadia Combination Valve Complete 7034468

The Heatrae Sadia Combination Valve - Complete (Post December 2016) is a cold water combination valve assembly supplied for use on Heatrae Sadia unvented hot water cylinders. It combines the pressure reducing and expansion relief functions in a single valve body at the cylinder's cold water inlet. This version is specified for cylinders manufactured after December 2016.

• Reduced hot water flow at the taps despite adequate mains pressure
• Water discharging from the expansion relief outlet or tundish
• Pressure reducing section no longer holding a steady outlet pressure
• Dripping or weeping from the valve body or its connections
• Frequent or continuous operation of the relief discharge

• Confirm the cylinder is a post December 2016 build, as the pre and post dates use different valve assemblies
• Check the model and capacity on the cylinder data plate against the fit list above
• Identify whether the cylinder is Direct, Indirect, Solar or Electromax to confirm the correct assembly
• Inspect the existing valve connections and pipework before ordering to confirm the replacement will seat correctly
