Heatrae Sadia Expansion Valve Core Unit 95605828

The Heatrae Sadia 95605828 is a core unit for a combined check and expansion relief valve used on Megaflo unvented hot water cylinders. It forms the working core of the valve assembly, handling both the check function and the expansion relief function within the one body. Heatrae Sadia supplies this component as part of its water heater spares range for its own Megaflo appliances.

• Water continually discharging or weeping from the cylinder's relief outlet when the system is up to temperature and under normal operating pressure
• The valve failing to reseat or seal once the cylinder pressure has fallen back
• System pressure that will not hold steady, rising when the cylinder heats and failing to return to its cold fill pressure
• Visible scale, debris or damage around the check or relief seat preventing a clean seal
• Continued discharge after the valve has been operated manually

• Confirm the appliance is a Megaflo cylinder using internal expansion
• Check whether a replacement core unit or the complete valve assembly is required for the fault
• Compare the part number marked on the existing valve or its documentation against 95605828
• Confirm the cylinder model and installation details before ordering
